Glass fiber-optic cables are used where the temperature is too high for traditional photoelectrics. The transmitter and receiver are incorporated securely in a cool place. The M12 casing of the cables is screwed onto the sensor (M12 only). The other end can be mounted in any harsh environment with temperatures up to 400°F.
The transmitting and receiving end of the cables have an M12 casing and can be ordered at a 90° angle when needed for an application.
For through-beam applications, use two PI type cables, one for the transmitter and one for the receiver. For diffuse applications, a single PB type fiber-optic cable may be used. The transmitter and receiver connect side-by-side using the biffurcated cable. The infrared beam travels up one half of the cable away from the transmitter eye, reflects off the object to be detected, and then travels back down the other side of the cable to the receiver eye.
