The Omron ZE-N22-2 is a high-durability enclosed switch featuring a sealed roller plunger actuator and SPDT contact configuration. Designed for side mounting, it supports both general-purpose and sealed applications in automation, material handling, and industrial safety systems. It operates at speeds from 0.01 mm/s to 0.5 m/s and handles up to 120 mechanical operations per minute.
This model ensures reliable electrical performance with a rated electrical life of 500,000 operations (15 A, 250 VAC resistive load) and a mechanical life of over 10 million cycles. Built-in insulation meets industrial-grade standards, including 100 MΩ insulation resistance and dielectric strength of 2,000 VAC between terminals and ground. The booted structure provides protection against dust and light moisture, making it suitable for rugged industrial setups.
Operating between −10°C and +80°C and humidity up to 95% RH, the ZE-N22-2 ensures long-term reliability in challenging conditions with IP65 protection.
