WTB140-P430 is a photoelectric proximity sensor from SICK with background suppression, designed for reliable object detection. It features a rectangular plastic PBT housing (11 x 31 x 20 mm), an adjustable sensing range from 2 to 500 mm, and uses a visible red LED light source (680 nm). The sensor provides a PNP output, supports light/dark switching via a rotary switch, and connects with a 4-pin M8 connector. 

It has an IP67 rating for dust and water protection, making it suitable for industrial environments.
