The APEM Panel Switches IRR3S420B0S is a robust, sealed microswitch designed for industrial applications. With an IP67 rating, 1,000,000-cycle mechanical life, and 5 A 250 VAC ratings, it ensures reliable operation in harsh environments. Ideal for machinery and control systems requiring tactile feedback and high durability.
The APEM IRR3S420B0S is a high-reliability panel switch engineered for demanding industrial environments. Combining microswitch technology with a sealed IP67 rating, this switch delivers exceptional durability and performance in applications requiring precise switching actions. Its 1,000,000-cycle mechanical life and 5 A 250 VAC ratings ensure long-term functionality under extreme conditions, while tactile feedback and optional illumination provide intuitive operation. The switch’s compact 3 mm panel thickness and precise 1.6 mm total travel make it suitable for space-constrained installations.
The IRR3S420B0S operates as a Normally Open (NO) switch with a maximum current rating of 5 A at 250 VAC for resistive loads. It supports 50,000 cycles (function 7) and 25,000 cycles (function 8) under standard operating conditions. Insulation resistance exceeds 1 GΩ at 500 VDC, and dielectric strength reaches 750 Vrms between terminals and 2,000 Vrms between terminals and the frame. Initial contact resistance is limited to 100 mΩ max.
Engineered for extreme conditions, the switch maintains performance across a wide temperature range from -20 °C to +85 °C (-40 °F to 185 °F). Its IP67 rating ensures protection against dust and water immersion, with salt spray resistance meeting IEC 512-6 test 11f. The switch is also rated for 1,000,000 cycles in demanding environments.
With a total travel of 1.6 mm (±0.3 mm typical), the switch requires an operating force of 4 N (±2 N) and can withstand a maximum torque of 0.8 Nm applied to the nut. The 3 mm panel thickness and flat round actuator design allow for precise installation and optional marking, while soldering is safe at 320 °C for up to 3 seconds.
The IRR3S420B0S features a robust construction with a mechanical life of 1,000,000 cycles, ensuring long-term performance in industrial settings. Its microswitch technology provides consistent switching action, and the sealed design prevents environmental interference. The switch is suitable for applications requiring high reliability and minimal maintenance.
