Siemens 3RG7012-7BE00 Reflective Photoelectric Sensor

Siemens 3RG7012-7BE00 is a retro-reflective Opto‑BERO photoelectric sensor designed for long-range object detection with a fixed reflector. It operates on 10–30 V DC and provides a PNP switching output, with a sensing range of up to 12,000 mm (12 m) when a reflector is used. The model designation indicates a cable-ready configuration in the S-CAB family for straightforward installation. As part of Siemens' Opto‑BERO retro-reflective line, this sensor uses light emitted toward a reflector and evaluates the returned signal to detect targets, enabling reliable presence sensing in industrial environments where precise spacing and alignment are feasible. Common applications include automation and material handling on production lines or packaging systems that employ a fixed reflector to establish the sensing path.
