Overview

The SICK WTB2S-2P1151 is a background suppression photoelectric sensor from the W2S-2 series. It features a rectangular housing with screw terminals and PNP output. The device utilizes red light for detection within a range of 1 mm to 150 mm. It operates on a maximum DC voltage of 30V with a current draw of up to 50mA. The unit has an IP67 protection rating and functions between -25°C and 50°C. Response time is 500μs. It holds CE, UL, and EN IEC 63000 certifications.

Feature Summary

• Background suppression technology ensures reliable object detection independent of target color or surface reflectivity.
• Red light source provides consistent illumination for precise sensing applications.
• PNP switching output facilitates direct integration into standard industrial control systems.

Applications

• Automated assembly line monitoring
• Packaging machine object detection
• Conveyor belt sorting systems

Procurement Notes

Verify the specific part number against official SICK documentation to ensure compatibility with existing wiring configurations. Confirm that the required supply voltage aligns with the 30V DC maximum limit. Check for necessary certifications such as CE or UL depending on regional deployment requirements. Ensure environmental conditions remain within the specified temperature range.

Selection Notes

Select this model when background suppression is required for detecting objects with varying colors or reflective surfaces. The rectangular form factor and screw terminal connection suit fixed installations where vibration resistance is needed. Consider the 150mm maximum sensing distance for short-range applications requiring high precision.

Part Context

This component belongs to the W2S-2 series of photoelectric sensors manufactured by SICK. The series is designed for general industrial automation tasks requiring robust performance in challenging environments. The background suppression feature distinguishes it from diffuse reflection models, offering stability against background interference.

Replacement Considerations

Consult official SICK substitution guides for verified equivalent models. Ensure replacement units maintain identical mounting dimensions and electrical specifications. Verify that any substitute supports the same PNP output type and background suppression functionality.

FAQ

What is the sensing principle used by this sensor?

It uses background suppression (BGS) technology to detect objects based on distance rather than signal strength.

Is the sensor suitable for outdoor use?

Yes, it has an IP67 rating, providing protection against dust and temporary water immersion.
