The APEM Panel Switches IRR3F432 is a high-reliability microswitch autoswitch engineered for industrial control systems. 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 electrical and environmental demands while maintaining consistent performance across a wide temperature range from -20°C to +85°C.
The IRR3F432 delivers reliable electrical operation with a maximum contact resistance of 100 mΩ and dielectric strength of 750 Vrms between terminals. It supports 5 A 250 VAC loads with 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring long-term stability in industrial circuits.
Engineered for extreme conditions, the switch maintains performance in environments with temperature extremes from -20°C to +85°C. Its IP67 rating provides protection against dust and water immersion, while salt spray resistance (IEC 512-6, test 11f) ensures durability in corrosive settings.
With a total travel of 1.6 mm (±0.3 mm typical) and operating force of 4 N (±2 N), the switch ensures precise actuation without excessive wear. The 1,000,000-cycle mechanical life guarantees extended service life even under frequent use.
The switch features flying leads for easy terminal connection and a screw version rated for up to 4 A. It is designed for soldering at 320°C for 3 seconds, making it suitable for both manual and automated assembly processes.
