Product Description

The SICK WTB250-2N1131 Background Suppression Photoelectric Sensor is designed for industrial and automation applications requiring reliable object detection at distances ranging from 100 mm to 300 mm. Featuring a block sensor style, it uses a bright red light source for clear visibility during alignment. The sensor’s NPN output and 4-wire terminal design support flexible integration into control systems.

Equipped with an adjustable potentiometer marked with a positioning indicator, sensitivity and sensing range can be finely tuned for precise operation. The light/dark switching function can be selected via control cable, minimizing the number of variants required for different applications. Its IP67-rated plastic housing protects against dust and moisture, allowing use in harsh industrial environments.

This sensor supports operation over a temperature range from -25°C to 55°C, making it suitable for diverse conditions. The included stainless steel BEF-W250 mounting bracket facilitates easy and secure installation. The response time of 3 milliseconds ensures rapid detection in automation processes.

The WTB250-2N1131 model integrates both DC and universal AC/DC voltage options in a compact housing, enhancing flexibility. The rotatable male connector or cable option provides installation convenience. Certified to CE and UL standards, and compliant with EN IEC 63000 hazardous area regulations, this sensor meets rigorous industrial quality and safety demands.

BrightLight LED provides easily visible red light for alignment. Potentiometer with positioning indicator simplifies sensitivity adjustments. Light/dark switching via control cable reduces required device variants. Robust IP67 plastic housing protects against dust and water ingress.

Operating temperature range from -25°C to 55°C supports diverse environments. Quick 3 ms response time supports fast automation switching. Includes BEF-W250 stainless steel mounting bracket for ease of setup. Compatible with both DC (10 to 30 V) and AC/DC (24 to 240 V) power supplies.

This Photoelectric Sensor is ideal for industrial, manufacturing, automation, assembly line, packaging, and quality control applications, providing reliable background suppression and object detection. It suits use in electronics manufacturing lines, conveyor control, and other automated material handling systems requiring precise sensing with environmental protection.
