TR Electronic's OGL 55/54 optical angle sensor
OPTICAL ANGLE SENSOR
OGL 55/54 optical angle sensor, an alternative to a proximity sensor, is designed for presence and part detection. These fork sensors align the transmitter and receiver in a fork-like housing to guarantee sensor alignment. The sensor comes in metal or plastic housings and includes contamination detection via an LED that notifies users if oil, grease, dust or other contaminants are present.
