Photoelectric Retro-Reflective Sensor – WL160-F440

The WL160-F440 is a photoelectric retro-reflective sensor built for reliable and efficient object detection in industrial automation environments. With a compact rectangular housing and a sensing range of up to 6.5 meters (4.5 m with reflector PL80A), it’s perfect for confined spaces where high precision is essential.

This sensor utilizes a visible red LED light with a wavelength of 680 nm and features PNP switching output, making it easy to integrate into a variety of control systems. The sensor offers light/dark switching via a rotary selector and delivers a quick ≤ 0.5 ms response time, ensuring high-speed performance.

Its rugged plastic housing (PBT) and PMMA optics provide IP67 protection, making it suitable for harsh industrial conditions and a wide ambient temperature range.
