SICK Background Suppression Photoelectric Sensor Block Sensor 20 mm to 350 mm PNP Output Metal Housing IP66 WTB12-3P1231

The SICK WTB12-3P1231 is a high-performance Background Suppression Photoelectric Sensor designed for reliable object detection in industrial environments. This block sensor features a detection range from 20 mm to 350 mm with a PNP output type and robust metal housing, rated to IP66, IP67, and IP69K standards, ensuring durability against dust, water, and high-pressure cleaning.

Operating within a wide temperature range of -40°C to 60°C, the sensor supports a maximum current of 100 mA and utilizes a red light source for precise detection. Its fast response time of 330 microseconds enables quick and accurate sensing, ideal for dynamic processes.

Mounting is user-friendly with screw type mounts and multiple mounting hole options such as through holes, base blind holes, oblong through holes, and dovetail mounts, providing flexibility during installation. The sensor's robust die-cast zinc housing is optionally enhanced with a Teflon® coating for additional chemical resistance.

Advanced ASIC technology in the sensor boosts immunity to optical interference commonly encountered in industrial settings, while PinPoint LED technology presents a bright, small, and precise light spot facilitating easy alignment. The sensor provides precise switching characteristics for reducing downtime caused by sensor adjustments during production changes.

Featuring IO-Link capability, the sensor offers straightforward data access, flexible settings, monitoring, diagnostics, and visualization capabilities, streamlining integration with PLCs. These features make it suitable for applications spanning packaging, pharmaceuticals, food and beverage industries, ultrasonic welding stations, collision prevention at robot grippers, inline quality control, and identification of transparent or direct-marked 2D codes.

Additional applications include board detection, tray position monitoring, paper edge detection, dynamic measurement of gaps, and flexible parameter setting for various packaging types. The sensor is CE and UL certified and complies with hazardous area certification EN IEC 63000, ensuring safety and quality standards are met.
