The APEM Panel Switches IRR3F472L0B is a robust microswitch designed for industrial applications. Featuring IP67 sealing, tactile feedback, and a flat round actuator, it delivers reliable operation with 1,000,000 cycles and 5 A current handling. Ideal for demanding environments requiring high durability and precise switching.
The APEM Panel Switches IRR3F472L0B is a high-reliability microswitch engineered for industrial control systems. This panel switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for precise operation in harsh environments. With a mechanical life of 1,000,000 cycles and a current rating of up to 5 A for resistive loads, it ensures long-term performance in applications requiring frequent switching and high environmental resilience.
The IRR3F472L0B delivers reliable electrical performance with a maximum current rating of 5 A for 250 VAC resistive loads. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring durability in high-frequency switching applications. Initial contact resistance remains below 100 mΩ, and dielectric strength exceeds 750 Vrms between terminals, with 2,000 Vrms between terminals and frame for robust electrical isolation.
Engineered for extreme conditions, the switch maintains performance across a wide temperature range (-20°C to +85°C) and withstands salt spray testing (IEC 512-6, test 11f). Its IP67 rating guarantees protection against dust and water immersion, making it suitable for outdoor installations and marine environments without compromising functionality.
With a total travel of 1.6 mm (±0.3 mm typical), the switch requires a minimal operating force of 4 N (±2 N) and can handle a maximum torque of 0.8 Nm when tightened. The panel thickness is limited to 3 mm (max), ensuring compatibility with standard industrial panel assemblies.
The IRR3F472L0B supports both screw and flying lead terminals, with optional illumination for enhanced visibility in low-light conditions. Its tactile feedback and flat round actuator design allow for precise user interaction while accommodating marking requirements for traceability in manufacturing and maintenance processes.
