Omron XS3H-M421-402-PR Sensor Cable

Modern robotic automation requires connection components that remain dependable under constant motion, repetitive bending, and exposure to industrial contaminants. The Omron XS3H-M421-402-PR Sensor Cable is developed for these demanding environments by combining a straight M8 male connector with a flexible oil-resistant PUR cable and open wire termination. This configuration supports direct integration into machine control systems while providing mechanical durability for dynamic applications. The product specifications are based on Omron technical documentation.

Unlike standard sensor cables intended primarily for stationary equipment, the Omron XS3H-M421-402-PR Sensor Cable is identified as a robotic cable, making it suitable for applications involving continuous cable movement. Its PUR jacket provides improved resistance to abrasion and industrial oils compared with conventional PVC cables, helping maintain cable integrity in automated production environments.

Omron XS3H-M421-402-PR Technical Description

This model belongs to the Omron XS3H series of waterproof M8 connectivity products. It features a four-pole straight male connector on one end and open wire leads on the opposite side, allowing flexible termination inside PLC cabinets, distributed I/O stations, or customized electrical assemblies.

• M8 straight male connector
• Four electrical contacts
• PUR oil-resistant robotic cable
• 2-meter cable length
• IP67 protection when mated
• Open wire termination
• Brass coupling nut
• Designed for robotic applications

Omron XS3H-M421-402-PR Working Principle

The cable establishes electrical communication between field sensors and industrial controllers. Once the M8 connector is secured to its mating connector, electrical power and signal lines are transmitted through the four internal conductors. The threaded coupling minimizes loosening caused by vibration or repetitive movement.

The open wire end enables engineers to terminate individual conductors directly into PLC input modules, remote I/O systems, machine terminals, or electrical control panels according to project requirements.
