The APEM Panel Switches IRR3S432 is a robust microswitch-based autoswitch designed for industrial applications. Featuring IP67 sealing, tactile feedback, and a 5 A 250 VAC rating, this switch ensures reliable operation in harsh environments with minimal maintenance. Ideal for machinery and control systems requiring high durability and precise switching.
The APEM Panel Switches IRR3S432 is a high-reliability microswitch-based autoswitch engineered for demanding industrial environments. With an IP67 rating for dust and water resistance, this switch delivers exceptional durability in challenging conditions. Its tactile feedback ensures precise user interaction, while the 5 A 250 VAC current rating and 1,000,000 cycle mechanical life make it suitable for critical applications where long-term performance and reliability are essential. The switch's compact 3 mm panel thickness and flat round actuator design allow for seamless integration into control panels without compromising functionality.
The IRR3S432 operates within a 5 A 250 VAC current rating for resistive loads, delivering 50,000 cycles for function 7 and 25,000 cycles for function 8. Initial contact resistance is ≤100 mΩ, and dielectric strength reaches 750 Vrms between terminals and 2,000 Vrms between terminals and frame. The switch supports microswitch technology with tactile feedback for precise switching actions.
Engineered for extreme conditions, the IRR3S432 withstands temperatures from -20 °C to +85 °C (-40 °F to 185 °F). Its IP67 rating ensures protection against dust and water ingress, with salt spray resistance meeting IEC 512-6 test 11f. This makes the switch ideal for outdoor or marine environments where exposure to harsh elements is common.
With a panel thickness of 3 mm (max), the IRR3S432 features a total travel of 1.6 mm (±0.3 mm) and an operating force of 4 N. The switch includes a flat round actuator for optional marking and is designed for screw versions up to 4 A, with illuminated or non-illuminated options available.
The IRR3S432 delivers 1,000,000 mechanical cycles with a 5 A 250 VAC rating, ensuring long-term performance in high-stress applications. Its insulation resistance of ≥1 GΩ at 500 VDC and robust construction support consistent operation in demanding industrial settings without frequent maintenance.
