SICK Background Suppression Photoelectric Sensor, Block Sensor, 1 mm to 18 mm Detection Range, PNP Output WTB2S-2P3110

The SICK WTB2S-2P3110 background suppression Photoelectric Sensor is a compact, panel-mount block sensor designed for detecting small parts and precise edge detection in industrial automation contexts. This sensor reliably distinguishes objects from backgrounds within a detection range of 1 mm to 18 mm by employing a visible pinpoint LED that produces a focused 2 mm light spot.

With a swift response time of 0.4 milliseconds, it supports high-speed switching operations up to 1,200 Hz, making it ideal for fast pick-and-place lines, quality inspection stations, and component counting in conveyor-fed electronics manufacturing.

The sensor’s PNP output type ensures easy integration with common industrial control systems, while the IP67 rated enclosure, molded from robust polycarbonate and ABS, protects against dust, water, and harsh environments encountered in manufacturing, laboratory, and automation settings.

It operates effectively within a voltage range of 10 V to 30 V DC and draws typically 20 mA current without load. Temperature resilience from -25°C to 50°C allows deployment in varied environments.

The device includes protections such as reverse polarity on supply and output, alongside overcurrent and short-circuit safeguards, enhancing reliability and safety in operation.

Applications encompass high-speed part presence detection, small-object sorting, precise position sensing in compact automation assemblies, and quality control inspections. This sensor is suitable for use across industrial automation, manufacturing, laboratory instrumentation, and electronics production lines.

Provides reliable background suppression for small-object detection up to 18 mm. Features a visible pinpoint LED emitting a 2 mm spot for accurate sensing. Response time of 0.4 ms enables high-speed switching up to 1,200 Hz.
