Overview

The SICK WTT12L-B2526 is a block-shaped background suppression photoelectric sensor from the PowerProx series. It features an NPN output and a red light source, connected via a 5-pin M12 connector. The device operates on a maximum DC voltage of 30V with a maximum current of 100mA. It provides a detection range from 50 mm to 1.4 m and has a response time of 16.7 ms. The unit is constructed from plastic with an IP67 protection rating, suitable for operating temperatures between -35°C and 50°C. It holds CE and UL certifications.

Feature Summary

• Background suppression technology ensures reliable detection regardless of target surface color or reflectivity variations.
• Red light source provides clear visual indication of the switching point for precise alignment.
• Robust plastic housing design supports operation in demanding industrial environments.

Applications

• Detection of plastic components such as methyl methacrylate parts
• Automated assembly line object verification
• Packaging machinery material presence sensing

Procurement Notes

Verify the specific part number WTT12L-B2526 against official SICK documentation to confirm compatibility with your control system's voltage requirements. Ensure that the NPN open-collector output configuration matches your PLC input specifications. Confirm that the 5-pin M12 connector interface aligns with your existing cabling infrastructure before procurement.

Selection Notes

Select this model when consistent detection of varying surface materials is required within the specified distance range. The background suppression feature makes it suitable for applications where mounting constraints prevent fixed-distance setups. Consider the NPN output type if interfacing with standard industrial controllers requiring sinking inputs.

Part Context

This component belongs to the PowerProx series by SICK, designed for robust industrial automation tasks. The series emphasizes reliability in detecting objects against complex backgrounds. As a background suppression sensor, it utilizes triangulation principles to maintain accuracy independent of target reflectivity, distinguishing it from standard through-beam or diffuse sensors.

Replacement Considerations

Consult SICK technical documentation for direct cross-references. Verify that any substitute maintains the same background suppression functionality, NPN output polarity, and M12 connector pinout to ensure seamless integration without rewiring.
