Photoelectric Sensor – WTB2S-2P3160

The WTB2S-2P3160 | W2 miniature photoelectric sensor is engineered for precise object detection in confined applications. With a slim 7.7 mm wide housing and reliable background suppression, it offers consistent detection within a 1 mm to 66 mm range, optimized for small objects even in complex backgrounds.

Its PinPoint red LED ensures a sharp, highly visible light spot (Ø 4.5 mm at 40 mm), supporting accurate alignment and reliable sensing. Delivering high-speed operation with a response time under 0.5 ms and 1,000 Hz switching frequency, this sensor fits seamlessly into high-speed automation tasks.

Built with an IP67-rated ABS/PC housing, and prewired with a 200 mm cable and M8 3-pin connector, the WTB2S-2P3160 ensures both durability and quick installation. Ideal for electronics manufacturing, assembly lines, and miniature conveyor systems.
