SICK WF50-40B416 Industrial Fork Sensor 4-Pin

The SICK WF50-40B416 is a compact fork-style photoelectric sensor from the WF50 family, designed for presence/absence detection between the fork blades on conveyors and automation lines. It offers a 50 mm sensing range and a 40 mm fork depth, with either NPN or PNP switching outputs and a light/dark mode, accessible via a 4-pin M8 connector and powered from a DC supply up to 50 V. The aluminum housing carries IP65 protection for rugged industrial environments, and the output current is rated up to 100 mA with an operating temperature range from -20 to 60 C, making it suitable for machining, packaging, and material-handling applications that require a robust, compact fork sensor.
