PMR10RI is a retro-reflective photoelectric switch designed for object detection applications with a sensing range of up to 10 m using an ER 4 reflector. It features a multi-voltage supply capability operating from 10.8 to 264 VDC or 21.6 to 264 VAC (45-65 Hz), with relay output contacts rated for 3 A at 250 VAC (resistive loads). The unit utilizes modulated infrared light (880 nm GaAlAs LED) with fixed sensitivity and is immune to ambient light up to 5,000 lux. Housed in a reinforced polycarbonate enclosure measuring 25 x 65 x 81 mm with IP 67 protection, it operates reliably in temperatures from -25°C to +55°C. This photoelectric switch is ideal for industrial automation, conveyor systems, and material handling applications requiring reliable non-contact object detection.
