Pepperl + Fuchs Retroreflective Photoelectric Sensor, Block Sensor, 12 m Detection Range

The Pepperl+Fuchs 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.

Robust, compact photoelectric sensor for single-beam gate protection
