SICK Background Suppression Photoelectric Sensor, Block Style, 25 mm to 300 mm Detection Range, NPN Output WTB9L-3N2261

The SICK WTB9L-3N2261 is a background suppression photoelectric sensor designed for accurate detection of objects and features within a sensing range of 25 mm to 300 mm. It features a block sensor style with a rugged plastic VISTAL™ housing that provides mechanical resistance and durability, making it suitable for demanding industrial environments.

This sensor utilises a red light source and NPN output to enable reliable integration with common industrial controls. It operates at voltages up to 30 V DC and supports currents up to 100 mA, making it compatible with a variety of automation systems.

With IP ratings of IP69K, IP67, and IP66, the WTB9L-3N2261 is highly protected against water ingress, dust, and harsh conditions such as washdowns. The operating temperature range from -10°C to 50°C further supports its use across diverse industrial settings, including manufacturing lines, automotive assembly, and robotics.

Additional features include a fast response time of 500 microseconds and connectivity through a reliable 4-pin M8 connector. The sensor's design reduces machine downtime by suppressing optical and electromagnetic interference via SICK's SIRIC® technology.

Applications include detection of the smallest workpieces, object presence checking through narrow openings, inspection for protrusions or misalignments, and reliable detection of transparent or shiny objects in challenging backgrounds.
