The APEM Panel Switches IRP3S420B0S is a high-reliability microswitch engineered for industrial automation and control systems. This sealed, screw-mounted switch features an IP67 rating for dust and water resistance, ensuring performance in harsh environments. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC rating for resistive loads, it delivers consistent operation across a wide temperature range (-20°C to +85°C). The switch includes tactile feedback, optional illumination, and a flat round actuator for easy marking, making it suitable for applications where precise switching and durability are critical.
The IRP3S420B0S delivers reliable electrical performance with a 5 A 250 VAC rating for resistive loads, supporting 50,000 cycles in function 7 and 25,000 cycles in function 8. It features an initial contact resistance of 100 mΩ max and dielectric strength of 750 Vrms between terminals, ensuring robust electrical isolation and minimal resistance during operation.
Engineered for extreme conditions, this switch meets IP67 standards for dust and water resistance (IEC 60529) and withstands salt spray testing (IEC 512-6, test 11f). The operating temperature range spans -20°C to +85°C (-40°F to 185°F), making it suitable for both cold and hot industrial environments.
With a total travel of 1.6 mm (±0.3 mm typical) and a 4 N operating force, the switch ensures precise actuation with minimal wear. The mechanical life of 1,000,000 cycles demonstrates exceptional longevity, while the 0.8 Nm max torque for nut tightening provides secure installation without damage.
The flat round actuator allows for optional marking, enhancing identification in complex systems. Solder lugs facilitate reliable connections at 320°C max soldering temperature for 3 seconds. The screw version supports up to 4 A continuous current, ensuring safe operation in high-load applications.
