The Omron XE-Q21-2 is a durable limit switch designed for precision detection in industrial applications. It features a crossroller plunger actuator for accurate mechanical response and uses a single-pole double-throw (SPDT) contact system. With a side-mounting configuration and general-purpose enclosure, itβs ideal for integration into machines, conveyors, and position-detection mechanisms.
This switch operates at speeds from 0.01 mm/s to 0.5 m/s and withstands up to 120 mechanical operations and 20 electrical operations per minute. Built to handle 10 A at 125 VDC resistive load, it offers mechanical durability of 1 million cycles and electrical durability of 100,000 operations. It functions reliably in ambient temperatures from β10Β°C to +80Β°C and humidity levels up to 95% (sealed type). The XE-Q21-2 is built with a robust structure that resists vibration, shock, and dust, featuring a sealed body rated to IP65 protection.
