The APEM Panel Switches IRP3S420B0B is a robust, microswitch-based autoswitch designed for industrial applications. Featuring IP67 sealing, tactile feedback, and a flat round actuator for optional marking, this switch delivers reliable performance with a 1,000,000-cycle mechanical life, 5 A 250 VAC rating, and operation across -20°C to +85°C temperatures. Ideal for demanding environments requiring high durability and electrical safety.
The APEM Panel Switches IRP3S420B0B is a high-reliability microswitch autoswitch engineered for industrial use, combining IP67-rated sealing with tactile feedback for precise operation. This switch supports up to 5 A 250 VAC loads with a mechanical life of 1,000,000 cycles, ensuring long-term performance in harsh conditions. Its flat round actuator design allows for optional marking, while the screw version handles up to 4 A currents. The switch operates within a temperature range of -20°C to +85°C and meets stringent electrical safety standards including 750 Vrms dielectric strength and 1 GΩ insulation resistance at 500 VDC.
The IRP3S420B0B delivers reliable electrical performance with a maximum current rating of 5 A at 250 VAC for resistive loads. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring durability in high-frequency applications. Initial contact resistance is 100 mΩ max, and dielectric strength reaches 750 Vrms between terminals, with 2,000 Vrms between terminals and frame for enhanced safety.
Engineered for extreme conditions, this switch maintains performance across a wide temperature range (-20°C to +85°C). Its IP67 rating ensures protection against dust and water immersion, while salt spray resistance (IEC 512-6, test 11f) guarantees long-term reliability in corrosive environments. The switch also withstands 500 VDC insulation resistance testing.
Constructed with a 3 mm panel thickness (max), the switch features a flat round actuator for optional marking and a screw version capable of handling up to 4 A currents. The silver contact materials (gold-plated) ensure low resistance and corrosion resistance, while the transparent bushing bezel provides clear visibility for identification.
With a total travel of 1.6 mm (±0.3 mm typical), the switch requires a force of 2 N for operation and provides tactile feedback for user confirmation. The maximum torque applied to the nut is 0.8 Nm, and soldering is safe at 320°C for 3 seconds. The switch operates as a normally open (NO) contact with a 4 N operating force tolerance.
