Through-Beam Photoelectric Sensor – WS/WE100-2P3439

The WS/WE100-2P3439 is a reliable through-beam photoelectric sensor pair from SICK’s W100-2 series, engineered for fast and precise long-range detection up to 33 meters. Featuring visible red LED light (632 nm), it provides a large and clearly visible light spot (Ø 850 mm at 12 m), making alignment simple and intuitive.

Designed in a slim rectangular housing (11 x 31 x 20 mm), the sensor fits easily into tight spaces while maintaining robust performance. The integrated 270° potentiometer allows for fine sensitivity adjustment, and its light/dark switching mode can be selected via a rotary switch for flexibility in various applications.

With a switching frequency of 1,000 Hz and response time under 0.5 ms, this sensor is ideal for high-speed object detection tasks. It comes equipped with PNP output, is rated IP67 for durability in harsh environments, and includes two stainless steel mounting brackets for convenient installation.
