SICK WTB250-2N2451 Background Suppression Photoelectric Sensor is designed for industrial automation applications requiring precise detection of objects within a 200 mm to 1 m range. This block sensor utilizes a red light source and features an NPN output type, offering reliable switching signals. Protected by an IP67 rated plastic housing, it is suitable for harsh environments and ensures protection against dust and water ingress. The sensor supports both cable and rotatable M12 connector variants, providing flexible installation options for diverse system configurations.
The sensing range and sensitivity can be easily adjusted using an integrated potentiometer with a position indicator, facilitating quick calibration and alignment, enhanced further by the bright red LED making targeting visible. Light/dark switching can be configured conveniently via the control cable, reducing the need for multiple device variants and streamlining inventory management.
The device comes with a stainless steel mounting bracket (BEF-W250 series) for secure and stable installation. Engineered to operate in temperature ranges from -25°C up to 55°C, it satisfies demanding factory and process conditions. Safety and quality are assured by CE and UL certifications alongside compliance to the EN IEC 63000 hazardous area standard.
This sensor family integrates DC and AC/DC voltage types in a compact housing, expanding flexibility in power supply options. The WTB250-2N2451 variant supports a maximum DC voltage of 30V and current up to 100mA, with a quick response time of 3 ms, making it ideal for fast-paced automation environments.
Extensively utilized in automation, manufacturing, and processing industries, this sensor excels in object detection applications requiring high accuracy and environmental protection. Its robust features ensure long-term reliability and operational efficiency in industrial, laboratory, HVAC, and commercial settings.
