Its flat round actuator supports optional marking and illumination, making it ideal for demanding electrical systems.
The APEM Panel Switches IRR3F422L0S is a high-reliability microswitch autoswitch engineered for industrial environments. This switch delivers precise tactile feedback, exceptional durability with 1,000,000 operational cycles, and robust protection against environmental factors through its IP67 rating. Designed for applications requiring high current handling up to 5 A at 250 VAC, the IRR3F422L0S combines compact construction with advanced features like sealed terminals, flat round actuators for optional marking, and compatibility with both illuminated and non-illuminated configurations. Its performance specifications ensure consistent operation across extreme temperature ranges from -20°C to +85°C, making it suitable for critical industrial control systems.
The IRR3F422L0S delivers reliable electrical performance 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, ensuring long-term stability in high-demand applications. Initial contact resistance remains below 100 mΩ, while dielectric strength exceeds 750 Vrms between terminals and 2,000 Vrms between terminals and frame for robust electrical isolation.
Engineered for extreme conditions, the switch maintains functionality across a wide temperature range (-20°C to +85°C). Its IP67 rating provides comprehensive protection against dust, water immersion, and salt spray (IEC 512-6, test 11f), ensuring durability in harsh industrial settings without compromising performance.
With a total travel of 1.6 mm (±0.3 mm typical), the switch offers precise actuation while maintaining a mechanical life of 1,000,000 cycles. The operating force requirement of 4 N (±2 N) ensures consistent performance under varying loads, and the insulation resistance of 1 GΩ min. at 500 VDC guarantees electrical safety.
The switch features a 3 mm panel thickness (max) with flying leads for easy terminal connection. Its flat round actuator supports optional marking and illumination, while the screw version accommodates up to 4 A current ratings. Soldering is safe at 320°C for 3 seconds, enabling reliable assembly without damage.
