Retroreflective sensor
RLK29-55/25/116
< Robust, compact photoelectric sensor for single-beam gate
protection
< Not sensitive to ambient light, even with energy saving lamps
< Tamper-proof, no operating controls
< Version for universal voltages
< Relay output
Robust, compact, long range photoelectric sensors for detecting people, objects and vehicles
Function
Series 29 is a range of low-cost and, most importantly, reliable photoelectric sensors for monitoring industrial doors, elevators, and automatic
gates. Their high degree of protection makes them the ideal solution for tasks outdoors and at thresholds, and in harsh environments. These
"universal-voltage sensors" can be operated with any supply voltage from 24 V to 240 V, and with direct current or alternating current.
Application
l
Monitoring closing edges of automatic industrial doors and elevators
l Monitoring the swing range of automatic gates
l Detecting and tracking objects in material handling
