Product Description
The SICK WTB8-P2131 Background Suppression Photoelectric Sensor is designed for precise object detection in industrial automation environments. It features a block sensor style with background suppression capabilities allowing accurate sensing within a 30 mm to 300 mm detection range. The sensor utilizes an LED light source housed in robust ABS plastic and is intended for panel mounting applications.
Equipped with a PNP output type, this sensor offers direct sourcing for control inputs and includes a 3-pin M8 terminal for straightforward wiring and maintenance. Its IP67-rated enclosure provides excellent protection against dust and water ingress, making it suitable for demanding factory floor conditions. The sensor operates reliably within -25°C to 55°C ambient temperatures, supporting a maximum DC voltage of 30V and a maximum current of 30mA.
Compliance with DIN EN 62471 photobiological safety standards ensures safe operation of the LED light source. Additional certifications include ACMA, EU, UK approvals, and RoHS directive conformity, confirming its suitability for regulated environments.
This device’s rapid 500 microseconds response time enables efficient detection where speed is critical, such as on conveyor systems and automated pick-and-place cells. The short-circuit proof design improves operational reliability by reducing susceptibility to electrical faults.
Typical industrial applications include conveyor part presence detection, end-of-travel sensing on pneumatic actuators, and object counting where suppression of background signals prevents false triggers. The sensor’s robust design and reliable performance make it a practical choice for integration with PLC control systems requiring PNP sensor outputs.
Detects objects using background suppression technology. Block style housing made from durable Plastic ABS. Uses a 3-pin M8 connector for easy installation. Maximum DC voltage of 30V supports common industrial controls. IP67 rating for protection against dust and immersion.
Temperature range from -25°C to 55°C covers broad environments. 500 microseconds response time suitable for fast detection. Short-circuit proof to enhance sensor longevity. Certified to comply with ACMA, EU, UK standards and RoHS.
