The Omron ZE-QA2-2 is a durable enclosed limit switch designed for general-purpose industrial use. It features a roller arm lever actuator and side mounting structure, with SPDT (AC) contact configuration. Supporting operating speeds from 0.02 mm/s to 0.5 m/s, it is suitable for both slow and moderate motion equipment. The switch operates at 50/60 Hz and is rated for up to 15 A at 250 VAC (resistive load).
It offers long-term reliability with a mechanical life of 10 million operations and an electrical life of 500,000 operations. Built for industrial conditions, it resists vibration (10β55 Hz) and shock up to 1,000 m/sΒ² (destruction), with excellent insulation (100 Mβ¦ min.) and low contact resistance (15 mβ¦ max.). The ZE-QA2-2 performs reliably in ambient temperatures from β10Β°C to 80Β°C and in humidity up to 95% RH. Its sealed body ensures long-lasting performance with certified IP65 protection.
