The WLG4S-3F2234 is a miniature retro-reflective photoelectric sensor designed for precise object detection within a range of up to 3 meters. It features a reflex detection principle using a LED pin-point light source at a wavelength of 650 nm. The sensor has an M8, 4-pin connector and operates with a supply voltage of 10-30V DC. Its digital PNP output switches in dark switching mode, with a maximum output current of 100 mA and a typical current consumption of 30 mA. The housing is rectangular, slim, and made from durable material, with dimensions approximately 12.2 mm in width, 41.8 mm in height, and 17.3 mm in depth. Designed for precise detection, it employs coaxial optics without the need for a reflector when used in autocollimation mode.
