Omron XS3W-M421-402-R M8 Extension Cable

The Omron XS3W-M421-402-R Extension Cable is intended for extending electrical connections between M8-compatible industrial devices without altering signal integrity. Designed with a straight female connector on one end and a straight male connector on the other, the cable provides a practical solution for sensor wiring in industrial automation systems where additional cable length is required. The factory-molded construction helps ensure consistent connection quality while reducing installation complexity.

The two-meter PVC robot cable offers flexibility for routing through machine frames, cable carriers, and moving assemblies. According to the manufacturer’s technical documentation, the cable is configured with four contacts, rated for 125 VDC and 1 A, and provides IP67 protection when correctly connected.

Technical Description

The Omron XS3W-M421-402-R Extension Cable belongs to the XS3 Series of industrial connector products developed for reliable field-level connectivity. Its M8 threaded connectors provide secure mechanical engagement that helps prevent loosening caused by continuous machine vibration. The molded connector housing protects the cable termination while supporting stable electrical performance throughout long operating periods.

The four-contact arrangement makes the cable compatible with numerous industrial sensors, switches, and automation devices using standardized M8 interfaces. The PVC robot cable is engineered for applications requiring moderate flexibility, making it suitable for dynamic industrial equipment where repeated movement occurs during normal operation.

Working Principle

The cable operates as a passive extension between two compatible M8 interfaces. Electrical signals travel directly through the internal conductors from the connected field device to the control system without signal processing or amplification. Because the cable introduces no active electronic components, overall system performance depends primarily on the connected equipment and correct installation practices.

The threaded coupling system maintains secure mechanical locking, while integrated sealing elements preserve environmental protection against dust ingress and temporary water exposure when connectors are fully tightened.

Typical Applications

• Industrial proximity sensor connections
• Photoelectric sensor extension
• Machine automation systems
• Assembly equipment
