Omron XE-NA2-2 Limit Switch
Omron XE-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 side mounting supports installation where the target sweeps across the lever. Its SPDT DC contact configuration supports 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 XE-NA2-2 belongs to the XE Series within the sealed roller arm limit switch range from Omron control components for direct position, travel, and end-point sensing in side-mounted control applications.

The Omron XE-NA2-2 Limit Switch uses a sealed roller arm lever with a booted enclosure for machine position and travel detection. The roller arm is suited to cams and moving parts that sweep across the actuator, while side mounting supports installation where access is available from the side. Its built-in SPDT DC switch provides changeover control, 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 helps limit ingress around the enclosed mechanism during repeated use.
Mechanical durability is specified at 1 million operations minimum, while electrical durability reaches 100,000 operations minimum at 10 A, 125 VDC resistive load. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The XE-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 side-mounted roller-arm sensing where slow mechanical movement and DC switching are required.
