The Omron XS3W-M421-402-PR Extension Cable is designed to extend M8 sensor connections in industrial automation systems while maintaining reliable signal transmission under demanding operating conditions. Equipped with a straight M8 female connector, a straight M8 male connector, and a two-meter PUR robot cable, this model supports installations where continuous movement, oil exposure, and mechanical durability are important design considerations.
Technical Description
The Omron XS3W-M421-402-PR Extension Cable belongs to the XS3 connector family developed for factory automation applications. It features a four-contact configuration suitable for standard M8 sensor wiring and uses molded connectors to improve mechanical stability. The threaded coupling mechanism helps maintain a secure electrical connection even in machinery exposed to vibration.
The integrated PUR robot cable provides enhanced resistance to abrasion, industrial oils, and repeated flexing. With a rated voltage of 125 VDC and a rated current of 1 A, the cable is intended for reliable signal transmission between field devices and industrial control systems rather than power distribution.
Working Principle
The cable functions as a passive extension between two compatible M8 interfaces. Signals travel through four internal conductors without amplification or conversion, allowing connected sensors and controllers to communicate according to their original electrical specifications.
When both threaded connectors are fully tightened, the sealing elements help maintain the IP67 protection rating, reducing the risk of contamination caused by dust or temporary water exposure.
