GTB6-P4211 Photoelectric Proximity Sensor PNP 250mm IP67 | SICK

The Original New SICK GTB6-P4211 (1052438) is a miniature photoelectric proximity sensor from the G6 series, designed for precise, reliable object detection using background suppression technology. With a PinPoint LED light source and a highly visible red light spot, it simplifies alignment and delivers stable performance across a maximum sensing range of 5 mm to 250 mm (35 mm to 140 mm recommended). Housed in a compact rectangular ABS/PC enclosure rated IP67, it is engineered for space-constrained industrial environments. The sensor provides a PNP output with selectable light/dark switching and is configured via a mechanical potentiometer for quick on-site adjustment.
