PHOTOSWITCH® DIN Mount Fiber Optic SensorsPrecise Small Objects Detection for Hard to Reach Places

Fiber optic sensors are ideal for a variety of packaging and assembly applications including the detection of very small objects, parts verifi cation in hard to reach areas and color mark registration.

These sensors consist of a light amplifying unit and a fi ber optic cable that can be installed at the detection area allowing for remote sensitivity adjustment.

The Allen-Bradley® 45FVL, 45FSL and 42FT, along with the new extended range 45FPL provide a solution perfect for applications with signifi cant space limitations. These amplifi ers can be mounted side-by-side along a DIN-rail away from the actual application providing installation fl exibility and a superior noise immunity.

Rockwell Automation® also provides a wide range of Allen-Bradley fi ber optic cables with a variety of tips that allow the user to operate the sensors in diff use mode by using bifurcated cables or as a transmitted beam sensing solution when using individual fi ber cables. Fiber optic cables run inconspicuously from the amplifi ers to the target sensing area where they can be mounted into a standard through-hole or affi xed with a mounting bracket.

For color mark registration, the 45FVL off ers models with red, green, blue and white LED sources for detecting the widest variety of color marks on any background color. Some 45FSL models have a 30 μs response time making them ideal for very high-speed applications.

To reduce wiring installation time, the 45FSL and 45FVL feature a “Power Bus” option, allowing up to sixteen sensors to be powered through a single hard-wired connection.

The 42FB analog output provides a 1-8V DC voltage output that is proportional to the amount of light the unit receives making it ideal for applications where the relative position of the target is required.

For medium duty applications, the 42FT is the sensor of choice with its IP66 rated enclosure that allows the user to install the amplifi er outside of a control cabinet.
