The Omron XS3W-M421-401-PR Extension Cable is engineered to provide a reliable M8 connection between industrial sensors and automation equipment while supporting dynamic machine movement. This model combines a straight M8 female socket with a straight M8 male plug and incorporates a PUR oil-resistant robotic cable, making it suitable for installations where mechanical flexibility and resistance to industrial fluids are required. The manufacturer specifies a four-pole configuration, a one-meter cable length, and an IP67 protection rating for properly connected assemblies. :contentReference[oaicite:0]{index=0}
Technical Description
The Omron XS3W-M421-401-PR Extension Cable belongs to the XS3 connector family developed for factory automation applications. Its four-contact arrangement supports standard M8 sensor wiring, while the threaded locking mechanism helps maintain a secure electrical connection under vibration. The PUR cable jacket offers improved resistance to oils and repeated flexing compared with conventional PVC cables, making it appropriate for robotic equipment and moving machine components.
With a rated voltage of 125 VDC and a rated current of 1 A, the cable is designed for signal transmission in industrial control systems rather than power distribution.
Working Principle
The cable operates as a passive extension between two compatible M8 interfaces. The female connector attaches to the field device, while the male connector connects to the controller-side cable or I/O module. Internal conductors maintain uninterrupted electrical continuity without introducing active electronic components.
The threaded M8 coupling prevents accidental loosening caused by vibration, while integrated sealing elements preserve the IP67 protection level after correct installation.
