Procurement Notes

Verify the exact order code against the manufacturer's current catalog to ensure compatibility with existing system voltage levels and wiring configurations. Confirm that the NPN output logic aligns with the input requirements of the connected PLC or controller interface before finalizing procurement.

Selection Notes

Select this model when a short sensing distance of approximately 6mm is sufficient for the application. Ensure the target material reflects light adequately for retroreflective operation. Consider environmental factors such as ambient light interference if used in open environments.

Part Context

This component belongs to SICK's portfolio of industrial photoelectric sensors. These devices are engineered for robust performance in manufacturing environments. The 2140814 variant specifically addresses needs for precise, short-range detection using standard NPN interfaces common in European and global automation standards.

Replacement Considerations

Consult official SICK documentation for direct cross-references. Ensure any substitute maintains the same NPN output polarity and sensing range to avoid rewiring or control logic modifications.
