RAY-N
RAY-N photo-eyes are monitored sensors, using the same proven technology as the OPTOEYE. When the signal between transmitter and receiver is interrupted, the sensor sends a signal to the operator to stop and reverse the door. These sensors are long range (13 m), yet are NEMA 1 rated for price-sensitive applications. Also, the versatility of threaded design allows for flush mounting (for example, within the guide of a rolling door) or mounting to a bracket for easy installation.
