I.S. Photoelectric Proximity Sensors-Opposed

The following are NAMUR intrinsically safe sensors and are powered by a Digital Input Barrier which may be selected by clicking on any link for Digital Input Barrier.

These sensors consist of a separate emitter and receiver, positioned opposite each other so the light from the emitter shines directly on the receiver.  An object is sensed when it interrupts the light beam between the two. The opposed transmitter-receiver mode is the most efficient of the sensing modes and offers reliable sensing through dirt, fog or other challenging environments.

Don't forget to order the plug and lead (cordset) also if ordering a sensor with a connector.
