The Omron ZE-Q22-2 Limit Switch is a general-purpose enclosed switch with a roller plunger actuator, SPDT (AC) contacts, and side mounting. Operating speed ranges from 0.01 mm/s to 0.5 m/s. Mechanical operation frequency is 120 operations per minute and electrical operation frequency is 20 operations per minute. Initial contact resistance is 15 mΩ maximum, insulation resistance is 100 MΩ minimum at 500 VDC, and frequency is 50/60 Hz. IP65 protection is specified. Mechanical durability is ten million operations minimum, while electrical durability is 500,000 operations minimum under the listed 15 A at 250 VAC resistive-load test condition.
Operating temperature ranges from -10 to 80°C with no icing. Relative humidity is 35 to 85% RH for the general-purpose type. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Destructive shock resistance is 1,000 m/s² maximum; the source also lists malfunction values of 100 m/s² maximum and 50 m/s² maximum without visible labels separating their conditions. The 15 A at 250 VAC value is retained only as the electrical-durability condition rather than a separate rated-load claim. The model is best identified by roller plunger, side mounting, SPDT (AC), operating-speed range, and IP65 protection. For another ZE Series side-mounting plunger model, see ZE-Q-2.
