Ideal for demanding environments requiring high durability and precise switching.
The APEM Panel Switches IRR3S422 is a high-reliability microswitch-based autoswitch engineered for industrial control panels. This panel switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in harsh conditions. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC current rating, it meets stringent requirements for durability and performance in demanding environments. The switch's robust construction, including a 3 mm panel thickness and 1.6 mm total travel, ensures consistent performance across a wide temperature range from -20°C to +85°C.
The IRR3S422 operates as a normally open (NO) switch with a maximum current rating of 5 A at 250 VAC. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8. Initial contact resistance is 100 mΩ max., and dielectric strength ranges from 750 Vrms between terminals to 2,000 Vrms between terminals and frame.
Engineered for extreme conditions, the switch withstands temperatures from -20°C to +85°C (-40°F to 185°F). It meets IP67 standards for dust and water resistance, with salt spray testing compliance (IEC 512-6, test 11f). The switch also handles 500 VDC insulation resistance and 750 Vrms dielectric strength.
With a 3 mm panel thickness (max), the switch features a total travel of 1.6 mm (±0.3 mm typical). The operating force is 2 N, and the maximum torque for nut application is 0.8 Nm. Soldering is compatible with 320°C for up to 3 seconds.
The IRR3S422 delivers 1,000,000 mechanical cycles with a 5 A 250 VAC rating. Its microswitch technology ensures precise switching with tactile feedback, while the IP67 sealing guarantees long-term performance in industrial settings.
