SICK Background Suppression Photoelectric Sensor Block Style PNP Output 4 mm to 90 mm Detection Range IP67 WTB2S-2P3275

SICK WTB2S-2P3275 is a background suppression photoelectric sensor designed for high reliability and compact installation in industrial automation applications. It features a block style sensor with PNP output and a detection range spanning from 4 mm to 90 mm. The sensor utilizes PinPoint 2.0 LED technology delivering laser-like or line-shaped light spots for accurate object detection and is capable of sensing highly-transparent and reflective objects.

The sensor housing is made of robust plastic material with screw mounting type and is rated IP67, making it suitable for harsh industrial environments. It operates on a maximum DC voltage of 30V with a maximum current rating of 50 mA, ensuring safe integration into automation systems. The device supports remote setup and monitoring through IO-Link, enabling flexible configuration and real-time condition monitoring from confined spaces.

With a response time of 500 microseconds, this sensor provides fast detection and reduces false triggering, enhancing process reliability. It complies with CE and UL certifications, including EN IEC 63000 hazardous area certification, confirming adherence to international safety and quality standards. Operating temperature ranges from -25°C to 50°C, allowing deployment in diverse industrial settings.

The sensor's advanced background suppression enables detection of objects with extremely low reflectivity, such as ultrablack surfaces, down to 1%. This capability, combined with its compact form factor, enables space-saving machine designs without requiring reflectors or through-beam setups.

Typical applications include detection of transparent ampules and vials in pharmaceuticals, solar cells in electronics, smartphone modules, small mounting parts such as pins and screws, and many other manufacturing and logistics automation scenarios. The versatile sensor supports Industry 4.0 implementations with integrated counters, timestamps, and false trip suppression functions.

This sensor features background suppression with stable detection even on ultrablack objects with 1% reflectivity. PinPoint 2.0 LED technology enables extended sensing distances with high operating reserves. Equipped with red light source and 4-pin connector terminal for reliable connection.

Designed for easy mounting via screw type and robust plastic housing for durability. Supports remote setup and monitoring via IO-Link for confined space installations. Response time of 500 microseconds ensures fast and accurate detection.

Certified with CE, UL standards and rated IP67 for protection against dust and water. Operates reliably between -25°C and 50°C temperature range. Widely used in pharmaceutical, logistics, automotive, and manufacturing industries for precise object detection.
