SICK WTB12-3P2461S58 1047850 Photoelectric Proximity Sensor PNP 500mm

SICK WTB12-3P2461S58 is a compact photoelectric proximity sensor with background suppression from the W12-3 series. PinPoint LED technology with visible red light provides a precise light spot for reliable object detection independent of background. PNP output with selectable light/dark switching. M12 male connector, 4-pin, metal housing, IP66/IP67.

Applications:

• High‑speed conveyor object presence and positioning (up to 1,500 Hz switching frequency)

• Packaging machinery for product counting and sorting

• Automated assembly line part detection and positioning

• Material handling and logistics automation

• General factory automation in demanding environments
