Cherry Sensor Products

Cherry speed and proximity sensors bringtremendous freedom and unmatched performance and reliability to your consumer, commercial and industrial equipment designs. Available in a varietyof standard sizes and configurations, they serve as highly reliable replacementsfor mechanical and optical components in applications where performance and reliability cannot be compromised, regard-less of the operating environment. Dirt.Grime. Heat. Even electrical interference.

Cherry speed and proximity sensors continueto perform. Andwith no movingparts, they do sowith a virtuallyinfinite lifeexpectancy.

Our full line of speedand proximity sensorsis divided into fiveproduct series to easeyour selection process.These product series,detailed in this catalog,are as follows:

• MP Series — Magnetic Proximity Sensors

• GS Series — Geartooth Speed Sensor Assemblies

• SD Series — Geartooth Speed &Direction Sensors

• VN Series — Vane Switches

• Miscellaneous Products & Accessories

Your Total Design Partner

To augment our line of standard sensorproducts, Cherry also offers a wide varietyof packaging and wiring options to suit yourapplication. If your design calls for a productwe don’t currently offer as part of our standard line, our in-house design staff willwork with you to develop a semi- or fully-custom solution to your exact requirements.

Utilizing the latest design modeling andrapid prototyping tools, we offer unequaledproduct development assistance.

• In the initial design stages, our magneticmodeling capabilities serve to verify the design concept, while also helpingto obtain the optimal match of sensorand magnet to your application.

• Once the design concept is approved,we enter the physical prototypingstage, using Pro Engineering solid modeling software to create the physical design and stereolythographyfor rapid prototyping. Our in-houseplastic molding capabilities allow us to provide prototype or productionparts in a very timely manner.

• Finally, our certified qualification laboffers complete environmental testing,product life testing and magnetic testcapabilities; the final step in readying your sensor solution for final production.

World-ClassManufacturing

Incorporating the Kaizen philosophy of continual improve-ment, our AdvancedManufacturing Grouphas designed and developed proprietaryassembly equipment to provide youunmatched productionflexibility. The capabilities of our ISO9001Certified Manufacturing Center range fromplastic molding to automated surface mount circuit board assembly.

From concept to completion, Cherry is yoursource for Advanced Sensor Solutions.

Some applications require the sensor have only two connections. To accommodate these situations, several Cherry sensor assemblies are equipped with a 2-Wire interface (whichmay be tested as shown in the block diagram). When the sensor is idle, current flowing into the device via Pin 1 and out via Pin 3 is limited to that needed to power the Hall effectdevice, a maximum of 6mA. When the sensor is active, the current flow will increase to a minimum of 10mA as the Hall effect device turns on the programmable current source. The voltage measured between the output and ground will therefore change by a minimum of 0.4 Vdc. If Pin 3 is connected to a comparator, the comparator output willswitch in response to the change in voltage at Pin 3 of the sensor. Alternatively, Pin 3 can be connected directly to ground and a load placed between Pin 1 and Vcc. In this case, Pin 1becomes the output lead to be connected to a comparator.

Sourcing outputs are often used in positive logic applications, where a high signal isrequired for an active state. Thus, sourcing outputs normally have current flowing out ofthe device output lead when the device is active. Because a pull-down resistor is requiredfor proper operation, sourcing outputs are compatible with CMOS logic, but not with TTL components. With the pull-down resistor connected as shown, the output will be“pulled down” to ground when off and (approximately) to Vcc when on.

Recommended pull-down resistor values are as follows:

Sinking outputs are often used in negative logic applications, where a low signal is required for an active state. Therefore, sinking outputs normally have current flowing into the device output lead when the device is active. Also called “open collector outputs,” sinking outputs are compatible with any logic family since a wide voltage range may beused for Vcc. Furthermore, the voltage level used to power the Hall effect assembly may differ from the pull-up resistor to which it is attached. The external pull-up resistor connected between the output and Vcc is required for proper operation. With the resistorconnected as shown, the output will be ”pulled up” to Vcc when off and (approximately) to ground when on.

Recommended pull-up resistor values are as follows:

Proximity Sensor with Ring Magnet

Although commonly called ageartooth sensor, a solid-statespeed sensor can detect themotion of various ferrous objects with some type of discontinuous surface.

Examples of appropriate targets include:

■ Sprockets

■ Bolt Heads

■ Roller Chains

■ Cavities in a Smooth Surface

For best results, we recommend targets made from low carbon cold rolled steel. Other factorsthat influence sensor performance includegeartooth height and width, space between teeth, shape of the teeth and thickness of the target. As a general guideline, consider a targetwith the following minimum parameters:

Cherry’s solid-state magnetic proximitysensors also make excellent speedsensors when coupled with a rotatingring magnet. Advantages of this approach include: lower sensor cost, larger airgaps and absolute zero-speed sensing.
