45Ft Reflective Photoelectric Beam Sensor

E-931-S45RRQ

45Ft Reflective Photoelectric Beam Sensor

The ENFORCER E-931-S45RRQ Retro-Reflective Photoelectric Beam Sensor provides reliable sensing of objects that enter the space between the sensor and reflector, thus breaking the infrared beam. It is suitable for various types of detection such as sensing approaching vehicles to open a garage door or outdoor gate, as an entry notification for stores, to assist in measuring parking distances, or as an alarm notification, as well as many other uses.
