Baumer 12P5101 S35A Industrial Photoelectric Sensor

Baumer FEDM 12P5101/S35A is a miniature through-beam photoelectric receiver that serves as the receiver half of a Baumer through-beam pair, detecting object interruption across a 6 m sensing range when paired with its emitter. It operates from a 10–30 V DC supply, draws about 17 mA, and provides a PNP output with a maximum load current of 100 mA, complemented by short-circuit and reverse-polarity protection. The compact package features a 12.4 mm diameter, 35 mm long zinc die‑cast housing, a PMMA front window, and an M8 4‑pole connector, all rated to IP67 and functioning from -25 to +65 °C. Users can select either light-ON or dark-ON switching, and a yellow status LED indicates receiver activity while the response time remains under 1 ms. The device’s documented limit range (Sn) is 7.5 m, making it suitable for reliable detection in tight or constrained installations.
