Available. The Sick WLG4S-3E1134 is a miniature photoelectric retro-reflective sensor designed for precise detection of transparent objects in industrial automation applications. Featuring a sensing range from 0.01 m to 5 m, it utilizes a PinPoint LED light source emitting visible red light at a wavelength of 650 nm. The sensor's single-lens autocollimation system enables reliable detection through small openings, making it ideal for applications requiring detection of transparent materials. Its compact dimensions of 12.2 mm x 41.8 mm x 17.3 mm and lightweight design (30 g) facilitate easy integration into space-constrained environments. The sensor operates within a supply voltage range of 10 V DC to 30 V DC and offers a response time of less than 0.5 ms, ensuring rapid detection and response. Additionally, the WLG4S-3E1134 is equipped with a teach-in pushbutton for straightforward setup and adjustment, enhancing user convenience.
