Featuring IP67 sealing, tactile feedback, and a flat round actuator for optional marking, this switch delivers reliable operation with a 1.6 mm total travel, 5 A current rating, and 1,000,000 cycle mechanical life. Ideal for demanding environments requiring high durability and precise control.
The APEM Panel Switches IRR3F420B0S is a high-reliability microswitch-based autoswitch engineered for industrial control systems. This switch combines IP67-rated sealing to withstand harsh environments, tactile feedback for precise user interaction, and a flat round actuator that supports optional marking. With a 1.6 mm total travel and 1,000,000 cycle mechanical life, it ensures consistent performance under demanding conditions. The switch operates within a temperature range of -20°C to +85°C and handles up to 5 A with 250 VAC, making it suitable for critical applications where reliability and durability are paramount.
The IRR3F420B0S delivers robust electrical performance with a maximum current rating of 5 A at 250 VAC. It features a normally open (NO) electrical function and maintains an initial contact resistance of 100 mΩ max. The switch also demonstrates high dielectric strength, with 750 Vrms between terminals and 2,000 Vrms between terminals and frame, ensuring safe operation in high-voltage environments.
Engineered for extreme conditions, the switch meets IP67 standards for dust and water resistance, as well as IEC 512-6 salt spray testing (test 11f). This ensures long-term reliability in harsh industrial settings, including marine or outdoor applications. The operating temperature range spans from -20°C to +85°C (-40°F to 185°F), accommodating both cold and hot environments.
With a mechanical life of 1,000,000 cycles and a total travel of 1.6 mm (±0.3 mm), the switch provides exceptional durability. The operating force is 4 N (±2 N), and it supports a maximum torque of 0.8 Nm when applied to the nut. This combination ensures precise actuation and long service life even under repeated use.
The switch features flying leads for easy terminal connection and is available in both illuminated and non-illuminated variants. Its 3 mm panel thickness (max) and flat round actuator design allow for seamless integration into industrial panels. The switch is compatible with screw versions up to 4 A, offering flexibility in installation requirements.
