Photoelectric Proximity Sensor – WTB12-3P2411

The WTB12-3P2411 is a highly reliable photoelectric proximity sensor from the W12 series, designed with background suppression technology for accurate object detection, even against complex or reflective backgrounds.

Featuring a robust metal housing and infrared LED light (wavelength 850 nm), this sensor is ideal for harsh industrial environments, including material handling, conveyor systems, and automated machinery. The sensing range spans from 20 mm to 600 mm, with fine-tuned adjustment via a 5-turn potentiometer for precise setup.

The sensor connects via a standard M12 4-pin male connector and includes mounting clamps and screws, making installation quick and straightforward.
