1. OutlineA photoelectric sensor emits a light beam (visible or infrared) from its light-emitting element. A reflective-type photoelectric sensor is used to detect the light beam reflected from the target. A thrubeam type sensor is used to measure the change in light quantity caused by the target crossing the optical axis.

Features• Non-contact detection
Non-contact detection eliminates damage either to the target or sensor head, ensuring long service life and maintenance-free operation.
• Detection of targets of virtually any materialDetection is based on the quantity of light received, or the change in the quantity of reflected light. This method allows detection of diverse targets such as glass, metal, plastics, wood, and liquid.
• Long-detecting distanceThe reflective-type photoelectric sensor has a detecting distance of up to 2 m 6.6', the thrubeam type has a detecting distance of up to 40 m 131.2', and the retro-reflective type has a detecting distance of up to 50 m 164'.
• High response speedThe photoelectric sensor is capable of a response speed as high as 20 µs.
• Color differentiation possibleThe sensor has the ability to detect light from an object based on the reflectivity of its color, thus permitting color detection and differentiation.
• Highly accurate detectionA unique optical system and a precision electronic circuit allows highly accurate positioning and detection of minute objects.
Light beam emission methodsPulse emissionKEYENCE photoelectric sensors employ the pulse light beam emission method and use an LED or a semiconductor laser as the light source. This allows the sensor to emit, at intervals, a strong light beam of preset pulse duration, enabling a long-detecting distance, and stable detection with minimal interference from external light.

Continuous emissionThis allows the sensor to continuously emit a preset quantity of light. However, This method does not provide a long-detecting distance, due to weak light beams resulting from the limited current level of the light-emitting element, and is also vulnerable to extraneous light. Its response speed is also higher than that of the pulse beam emission method.

Luster recognition Target When the light beam hits a target, the beam reflects differently according to the luster of the target. The sensor detects the difference in luster based on how the beam reflects (specular or diffusive).• On-line detection is possible.• Detection is not affected by target color.• Transparent targets can be detected.
Optical passage confirmation
Target
The detecting area is formed by uniform parallel beams. When a target passes through this area, the received light quantity changes. Detection is performed based only on this change.• Minute targets can be detected.• Only moving targets are detected.• Detection is less affected by dirt or dust on the lens.

Self-diagnostic functionWhen optical misalignment or dirt or dust on the lens decreases the received light quantity, it results in unstable detection. An alarm output or indicator light is activated to inform the operator of a need for maintenance.
Misaligned optical axis
Dirt or dust accumulation on lens
FS01 and PS01 SeriesWhen the received light quantity exceeds the detection level but does not exceed the stable operation level “31 times continuously” or “for 8 seconds continuously”, the stability output is activated.Reset: When the stability output is activated, clean the front surface of the sensor head or realign the optical axis, so that the stable operation indicator (green LED) lights again. The stability output is reset when detection occurs with the stable operation indicator (green LED)
turned on.

4. Fiber Photoelectric SensorsThe photoelectric sensor incorporates optical fibers and can be installed in areas of limited space.
1. Operating principle and types• Operating principle
The optical fiber consists of the core and the cladding, which have different refractive indexes. The light beam travels through the core by repeatedly bouncing off the wall of the cladding. The light beam, having passed through the fiber without any loss in light quantity, is dispersed at an angle of approximately 60° and emitted to the target.
LED
Optical fiberCore (high refractive index)
Cladding (low refractive index)
Approx. 60°
• Optical fiber types Plastic-fiberThe core of the plastic-fiber consists of one or more acrylic-resin fibers 0.25 to 1 mm 0.01" to 0.04" in diameter, encased in a polyethylene sheath. Plastic fibers are light, cost-effective, and flexible and are used for the majority of optical fiber photoelectric sensors.
Glass-fiberThe glass-fiber consists of 10 to 100 µm 0.39 to 3.94 Mil diameter glass fibers encased in stainless steel tubing, allowing it to be used at high operating temperatures (350°C (662°F) max.).
2. Features• Versatile installation
A flexible optical fiber is employed for easy installation in areas such as small spaces between machines.
• Detection of small objectsThe light-emitting surface of the sensor head is extremely compact for stable detection of small objects.
• Stable operation in harsh environmentThe optical fibers are unaffected by electrical noise as no electric current flows through them.
• Heat-resistantThe heat-resistant fiber unit allows detection in a high temperature environment (350ºC (662ºF) max).
3. ShapeThe optical fiber sensors are divided into two categories: thrubeam and reflective. The thrubeam type comprises a transmitter and a receiver. The reflective type, which is a single unit, is available in 3 types: parallel, coaxial, and separate, according to the shape of the cross-section of the optical fiber.
Type Description
Parallel
Generally used for plastic fibers.
CoaxialHigh-precision type, consisting of a core (transmitter) and surrounding area (receiver). The operating position can remain the same regardless of the direction from which the target enters the detecting area.
Separate This type, containing several 10 µm-0.39 Mil glass fibers in diameter, has separate areas for the transmitter and receiver.
4. Bend radiusExcessively bent optical fiber will result in loss of light, causing reduced detection accuracy.KEYENCE fibers are available with extra-small bending radius.

5. Fiber length and detecting distanceThe detecting distance of a fiber photoelectric sensor varies depending on the fiber length.
6. Liquid level detection fiber unitsDetecting principle of liquid level detection fiber unit
Liquid immersion type (FU-93)When the fiber unit tip is present in the air, the emitted light is entirely reflected by the fiber unit’s PFA sheath and returns back to the receiver because the refraction factor between the PFA sheath and air is large. On the other hand, when the fiber unit tip is immersed in liquid, most of the emitted light is radiated into the liquid and does not return back to the receiver because the refraction factor between the PFA sheath and liquid is small. The FU-93 detects presence or absence of liquid by using the above characteristics.
• Fiber length vs. detecting distance (typ.)
Tube-mountable type (FU-95)When the tube, to which the fiber unit is mounted, contains no liquid, the emitted light is reflected by the inside wall of the tube and returns back to the receiver because the refraction factor between the tube and air is large. On the other hand, when the tube contains liquid, most of the emitted light is radiated into the liquid and does not return back to the receiver because the refraction factor between the tube and liquid is small. The FU-95 detects presence or absence of liquid by using the above characteristics.
7. Color differentiation chartsFor color differentiation, choose a light source producing a distinct difference in the reflectance of the 2 colors to be differentiated (i.e. select a light source that allows the sensitivity setting positions, corresponding to the 2 colors being discriminated, to be as far apart as possible).The charts below give reference data for color differentiation. Detection is, however, affected by the surface condition and luminosity of the target. Confirm the sensitivity difference of the colors to be differentiated using the actual target.

How to read the chart
The chart shows the difference in received light quantity between the FS-T1 and FS-V1 (red LED) and the FS-T1G (green LED) manufactured by KEYENCE.• Guide to color differentiation
When the received light level of one colors is 110% or more of the intermediate value of the two colors to be differentiated, the sensor stably detects the light being received. When the received light level is 90% or less, the sensor stably detects the light being interrupted.
Example: To differentiate red and whiteFrom the chart, the FS-T1 (red LED) shows similar received light levels for white and red; while the FS-T1G shows some difference. To calculate the excess gain of color differentiation, perform the following calculation:

A rough mounting surface may reflect the light beam, causing unstable detection.
Readjust the mounting heightChange the mounting height, or angle of the sensor head.
Target
An object in the background may reflect the light beam, causing unstable detection.
Black background
Target
Provide a background object of low reflectance, such as a black wall, to prevent the sensor from detecting a reflected light beam.
Target
Providedistance
Provide as great a distance as possible between the target and background object.
The small-spot definite-reflective type or fixed-distance type, whose detection is not affected by background objects, is recommended in cases where the above solutions are not possible.
2. Alignment of optical axis (thrubeam type)
1. Place the transmitter and the receiver face-to-face in a straight line.
2. Rotate the receiver clockwise or counterclockwise to find the range where the indicator LED lights. Set the receiver at the mid-point of the range.
3. Follow the same procedure for vertical alignment.

3. Mounting environment• Detecting shiny targets (retro-reflective type)
To detect mirror-surfaced targets, a retro-reflective type sensor with the P.R.O. (polarized reflective options) function (PZ2-61) is recommended. A sensor with the P.R.O. function has an optical system which is constructed so that the emitter emits only the horizontal component of the light wave and the receiver receives only the vertical component.
This allows mirror-surfaced targets to be stably detected.
The horizontal component ofthe light wave is emitted.
Reflector
When the horizontal component of the light wave strikes against the reflector, it scatters in all directions.
The horizontal component ofthe light wave is emitted.
Reflector
When the polarized light wavestrikes against a mirror-surfacedtarget, it does not scatter.
When using a retro-reflective type sensor that is not equipped with P.R.O. function, install the sensor head so that the distance from the target (L) is as far as possible, and the optical axis is at 30 to 45 degree-angle to the target.

• InterferenceWhen 2 or more sensors are installed side-by-side without sufficient distance between adjacent sensors, the receiver may detect a light beam emitted from the receiver of another unit, disturbing sensor operation. This phenomenon is called interference.
Suggestions for eliminating interference1. Use a sensor head with interference-prevention.
(Interference-prevention type sensors can be mounted side-by-side.)
2. Use a sensor head that can be switched to an alternate frequency. (Can be closely mounted.)
3. Allow sufficient distance between sensor heads to prevent interference. For further information, refer to the “Interference area” characteristics chart for each model.

* Set the transmitters and receivers so that a light beam emitted from a transmitter will not be received by the receiver of the adjacent sensor.
• Ambient light and effect of external lightKEYENCE photoelectric sensors employ the pulse light emission method, which ensures stable operation when external light is strong. However, a strong light beam, emitted in the direction of the optical axis of the receiver, will cause the sensor to malfunction. To correct this, change the angle of the sensor head, or provide a light-shield to prevent an external light beam from being emitted directly to the receiver.

4. Miscellaneous• When using a commercially available switching
regulator, ground its chassis grounding and earth grounding terminals.
• Isolate the sensor wiring from power lines and high voltage lines; otherwise, the sensor may malfunction due to noise interference.
• Handle the photoelectric sensor carefully when mounting. Strong impact to the sensor head may damage the sensor’s waterproof capability.
