The APEM Panel Switches IRR3V272 is a high-reliability microswitch autoswitch engineered for industrial control systems. This switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in harsh environments. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC current rating, it meets stringent electrical and environmental demands while maintaining consistent performance across a wide temperature range from -20°C to +85°C. The switch’s robust construction and precise engineering make it suitable for critical applications where reliability and safety are paramount.
The IRR3V272 delivers reliable electrical operation with a maximum current rating of 5 A at 250 VAC for resistive loads. It features a 750 Vrms dielectric strength between terminals and 2,000 Vrms between terminals and the front panel, ensuring robust electrical isolation. The switch maintains low initial contact resistance (100 mΩ max) and operates with a 2 N force requirement, providing consistent performance under varying load conditions.
Engineered for extreme conditions, the IRR3V272 meets IP67 standards for dust and water resistance, with salt spray testing compliance (IEC 512-6, test 11f). It operates effectively across a wide temperature range (-20°C to +85°C) and withstands environmental stresses such as salt spray, ensuring long-term reliability in industrial settings without maintenance.
With a total travel of 1.6 mm (±0.3 mm typical), the switch ensures precise actuation while maintaining a mechanical life of 1,000,000 cycles. The 0.8 Nm max. torque for nut tightening and screw terminals designed for up to 4 A continuous current support robust installation and long-term operational stability in high-demand applications.
The IRR3V272 is ideal for industrial control panels, machinery, and automation systems where high reliability, environmental resilience, and precise switching are critical. Its tactile feedback and optional marking capability enhance user experience and system traceability, making it suitable for applications requiring consistent performance in challenging environments.
