SICK Background Suppression Photoelectric Sensor, Block Sensor, 25 mm to 300 mm Detection, NPN Output, IP66 WTB4SL-3N1161

SICK WTB4SL-3N1161 Background Suppression Photoelectric Sensor is a block sensor designed to detect objects within a range of 25 mm to 300 mm. It employs a precise laser light spot with laser class 1 for highly accurate switching behavior. The sensor utilizes background suppression technology (BGS) to eliminate the effects of unintended background reflections, enhancing detection reliability.

This photoelectric sensor features an NPN output type with a 4-wire terminal connection and offers excellent immunity to optical ambient light, making it resistant to interference from modern energy-saving lamps. It has a maximum DC voltage rating of 30 V and a maximum current of 100 mA, with an operating temperature range from -10°C to 50°C. Its robust plastic housing is rated to IP66 and IP67 standards, ensuring protection against dust and water ingress.

The sensor includes a teach-in pushbutton that can be switched between detection of transparent and non-transparent objects, reducing the variety of sensors required and lowering storage costs. Adjustment can be performed via the teach-in button, potentiometer, cable, or optional IO-Link interface which also facilitates initial system diagnostics and additional sensor functionalities.

Applications of the WTB4SL-3N1161 sensor include overhang control to avoid overhanging panels, precise object positioning for quality checks, edge detection of glass panels, monitoring boreholes and additional features of parts, and verifying the presence of parts in robotic grippers. This sensor is engineered for industrial automation, manufacturing, laboratory instrumentation, and material handling systems.
