Omron ZE-N22-2 Limit Switch
Omron ZE-N22-2 is an enclosed limit switch with a sealed roller plunger for reliable position detection in industrial machinery. The booted actuator helps protect the operating mechanism, while the roller provides smooth contact with cams, slides, and moving machine parts. Side mounting supports straightforward installation, and the SPDT built-in switch provides changeover control for AC circuits. IP65 protection and an operating speed from 0.01 mm/s to 0.5 m/s suit varied machine movement. The ZE-N22-2 belongs to the ZE Series within the sealed enclosed limit switch range from Omron industrial control products for machine travel and position monitoring.

The Omron ZE-N22-2 Limit Switch uses a sealed roller plunger in a booted enclosure for reliable mechanical position detection. The roller actuator provides smooth contact with moving cams, slides, and machine parts, while the booted structure helps protect the operating mechanism in demanding industrial environments. Side mounting supports straightforward installation, and the SPDT built-in switch provides changeover switching for AC control circuits. Operating speed ranges from 0.01 mm/s to 0.5 m/s, with up to 120 mechanical operations per minute. IP65 protection supports factory use, and the operating temperature range extends from -10 to 80°C.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 500,000 operations minimum for a 15 A, 250 VAC resistive load. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The ZE-N22-2 withstands destructive shock up to 1,000 m/s², while malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Sealed versions support up to 95% relative humidity. These characteristics make the model suitable for repeated roller-plunger position sensing where a booted actuator and side-mounting format are preferred.
