It operates on a 10-30 VDC supply and provides a dual PNP/NPN switching output, rated at 200 mA continuous current. The sensor uses a visible red light beam that reflects off a separate reflector (not included), making it suitable for detecting opaque objects across a defined path without needing a separate receiver unit. The terminal connection allows direct wiring into a control cabinet or junction box. Housed in a plastic rectangular body measuring 36 x 72 x 87 mm (W x H x D), the WL36-B23 is a panel-mount style sensor. The listed code 172 on the component line identifies this specific variant within the SICK WL36 range.","metaTitle":"SICK WL36-B23 Photoelectric Retro-Reflective Sensor, 10-30 V","metaDescription":"SICK WL36-B23 retro-reflective photoelectric sensor, 10-30 VDC, PNP/NPN output, 200 mA, 36x72x87 mm.
