The Omron ZV-NA2-2 is a sealed enclosed limit switch equipped with a roller arm lever actuator and SPDT contacts for general-purpose switching. Designed for base mounting, it operates at speeds from 0.02 mm/s to 0.5 m/s and supports up to 15 A at 250 VAC (resistive load), making it suitable for demanding control applications.
This model offers a mechanical life of over 10 million operations and an electrical life of 500,000 operations. It features a sealed booted housing that ensures stable performance in environments with high humidity (up to 95%) and wide temperature variations from –10°C to 80°C. The ZV-NA2-2 withstands vibration (10–55 Hz, 1.5 mm double amplitude) and shock up to 1,000 m/s² (destruction rating). High insulation resistance (100 MΩ) and low contact resistance (15 mΩ max) ensure electrical reliability. The housing provides robust sealing and meets IP65 protection for industrial use.
