1141937

Overview

The SICK model 1141937 is a W2S series background-suppression photoelectric sensor. It features a rectangular housing with dimensions of 15.6 mm width, 48.5 mm height, and 42 mm depth. The device utilizes a visible red LED light source operating at a wavelength of 640 nm. It provides a maximum switching distance ranging from 20 mm to 350 mm depending on the target reflectivity. The output configuration is PNP with normally open/closed switching functionality. Electrical connections are established via an M12 connector with four pins. The unit includes a potentiometer for sensitivity adjustment and offers IP67 protection rating.

Feature Summary

• Background suppression technology ensures reliable detection regardless of object surface characteristics or color variations.
• Compact rectangular housing design facilitates installation in space-constrained industrial environments.
• Integrated potentiometer allows for precise manual sensitivity adjustment during setup.

Applications

• Detection of components on small conveyor systems such as solar wafers or PCBs
• Positioning fixtures when gripping objects using robotic arms
• Pallet detection within logistics and material handling输送 lines

Procurement Notes

Verify the specific ordering suffix against the official SICK catalog to confirm the exact cable length and connector type required for the application. Ensure that the PNP output logic matches the input requirements of the controlling PLC or safety relay. Confirm that the mounting bracket accessories are included if direct mounting is not feasible. Cross-reference the supply voltage specifications with the existing control cabinet power supply to prevent electrical mismatch.

Selection Notes

Select this sensor when background suppression is necessary to distinguish targets from complex backgrounds. The W2S series is suitable for applications requiring robust performance in varying lighting conditions. Consider the switching distance requirements relative to the target material's reflectivity. The M12 connection interface should align with the system's cabling standards. Evaluate the need for potentiometer adjustment versus teach-in capabilities based on installation constraints.

Part Context

This component belongs to the W2S product family of photoelectric sensors manufactured by SICK. The series is characterized by its compact form factor and high reliability in industrial automation. It complements other W-series sensors by offering specialized background suppression functionality. The model integrates standard SICK SIRIC technology for signal processing. It is designed for integration into automated machinery where consistent object detection is critical.

Replacement Considerations

Consult the official SICK replacement guide for cross-references. Verify compatibility with existing mounting hardware and wiring interfaces before substitution.
