LA29_LK29-Z-F1_31_116-SET Thru-beam sensor

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 “universalvoltage sensors” can be operated with any supply voltage from 24 V to 240 V, and with direct current or alternating current.
