Omron ZV-NA2-2 Limit Switch
Omron ZV-NA2-2 is a sealed enclosed limit switch with a roller arm lever for machine position and travel detection. The booted actuator helps protect the operating mechanism, while base mounting supports secure installation where cams or moving parts sweep across the lever. Its SPDT AC contact configuration supports 15 A at 250 VAC resistive-load switching, and the 0.02 mm/s to 0.5 m/s operating-speed range covers slow and faster mechanical movement. IP65 protection supports use around dust or moisture. The ZV-NA2-2 belongs to the ZV Series within the sealed roller arm limit switch range from Omron control components for position, travel, and end-point sensing.

The Omron ZV-NA2-2 Limit Switch uses a sealed roller arm lever with a booted enclosure for machine position and travel detection. The roller arm suits cams and moving parts that sweep across the actuator, while base mounting provides a stable installation format below the switch body. Its built-in SPDT AC switch supports 15 A at 250 VAC resistive load, and operating speed ranges from 0.02 mm/s to 0.5 m/s. The switch supports up to 120 mechanical and 20 electrical operations per minute. IP65 protection supports enclosed switching where dust or moisture may reach the switch body.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 500,000 operations minimum at 15 A, 250 VAC resistive load. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The ZV-NA2-2 operates from -10 to 80°C, with sealed-type humidity support up to 95% RH. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit repeated roller-arm position sensing where base mounting and AC switching are required.
