The APEM Panel Switches IRP3S422L0B is a high-reliability microswitch autoswitch engineered for industrial environments. This switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in challenging conditions. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC current rating, it provides dependable performance for critical applications where environmental resilience and long-term durability are essential.
The IRP3S422L0B delivers robust electrical performance with a 5 A 250 VAC rating for resistive loads, supporting 50,000 cycles. It features a 100 mΩ max initial contact resistance and 750 Vrms dielectric strength between terminals, ensuring stable operation under varying electrical conditions. The switch operates within a temperature range of -20°C to +85°C (-40°F to 185°F), making it suitable for extreme environments.
Engineered for harsh industrial settings, the IRP3S422L0B meets IP67 standards for dust and water resistance, with salt spray testing compliance (IEC 512-6, test 11f). This ensures long-term reliability in marine, chemical, or outdoor applications where exposure to moisture and corrosive elements is common.
With a total travel of 1.6 mm (±0.3 mm typical) and an operating force of 4 N (±2 N), the switch provides precise actuation with minimal wear. The screw version supports up to 4 A continuous current, while the microswitch technology ensures consistent performance over 1,000,000 cycles.
The switch features solder lugs for secure terminal connections and a flat round actuator for optional marking. Its 3 mm panel thickness (max) and 0.8 Nm max torque for nut tightening ensure compatibility with standard mounting practices and robust installation in industrial panels.
