The BOS 18M-PA-LH23-S4 is a diffuse photoelectric sensor with background suppression, housed in a brass, nickel-plated M18 body with a PMMA sensing surface and IP67 protection. It offers an adjustable operating distance of up to 150 mm and provides PNP normally open and normally closed outputs via an M12x1, 4-pin male connector, operating from 10-30 VDC. Such sensors are typically used in industrial automation applications for detecting objects regardless of colour or surface reflectivity, where connection into control panels or machine enclosures is required.
