The APEM Panel Switches IRR3S422L0B is a high-reliability microswitch-based autoswitch engineered for industrial environments. This switch delivers precise tactile feedback, exceptional durability with 1,000,000 mechanical cycles, and robust performance in extreme conditions. Its IP67 rating ensures protection against dust, water, and salt spray, while the 5 A current rating and 250 VAC voltage capability make it suitable for critical applications requiring high reliability and long service life.
The IRR3S422L0B delivers reliable electrical performance with a maximum current rating of 5 A at 250 VAC. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring long-term durability in high-stress applications. The initial contact resistance is 100 mΩ max, and dielectric strength reaches 750 Vrms between terminals and 2,000 Vrms between terminals and frame.
Engineered for harsh industrial conditions, this switch meets IP67 standards for dust and water resistance, as well as salt spray resistance (IEC 512-6, test 11f). The operating temperature range spans -20 °C to +85 °C (-40 °F to 185 °F), allowing it to function reliably in extreme environments without degradation.
With a mechanical life of 1,000,000 cycles, the IRR3S422L0B ensures exceptional longevity. The switch operates with a force of 4 N (±2 N) and a total travel of 1.6 mm (±0.3 mm), providing precise and consistent performance under repeated use. The 3 mm panel thickness (max) ensures structural integrity in demanding installations.
The switch features solder lug terminals with silver contact materials (gold-plated) for excellent conductivity and corrosion resistance. Its flat round actuator supports optional marking and illumination, while the 0.8 Nm max torque for nut tightening ensures secure assembly without damage.
