SICK GTB6-P4212 Mini Photoelectric Proximity Sensor

SICK GTB6-P4212 is a compact G6 miniature photoelectric proximity sensor with a 140 mm sensing range and background suppression, designed for reliable near-field detection in tight spaces and illuminated by a PinPoint LED that emits visible red light at 650 nm. It provides a PNP output, operates on 10–30 V DC, and uses an M8 4-pin connector; the package includes stainless steel mounting bracket BEF-W100-A. The device features a 6 mm light spot at 100 mm and is adjustable via a mechanical spindle with 5 turns, with an object remission of 90% on standard white targets as a reference. Sensing range specifications list 35–140 mm as the typical operating window, with broader capability up to 250 mm in certain configurations for extended reach. Part number 1052442 identifies this specific GTB6-P4212 model in SICK's G6 line.
