The APEM Panel Switches IRR3S492 is a high-reliability microswitch-based autoswitch engineered for industrial use. With an IP67 rating for dust and water resistance, this switch maintains performance in challenging environments such as those exposed to salt spray. Its tactile feedback provides immediate user confirmation, while the 5 A current rating and 250 VAC voltage capability ensure robust operation for critical applications. The switch's flat round actuator design allows for optional marking and illumination, enhancing usability in control panels where clear visual feedback is essential.
The IRR3S492 delivers reliable electrical performance with a maximum current rating of 5 A at 250 VAC for resistive loads. It features a normally open (NO) electrical function and an initial contact resistance of 100 mΩ max. The switch maintains dielectric strength of 750 Vrms between terminals and 2,000 Vrms between terminals and frame, ensuring safety in high-voltage applications.
Engineered for harsh conditions, the IRR3S492 meets IP67 standards for dust and water resistance, with salt spray resistance per IEC 512-6, test 11f. The switch operates effectively across a wide temperature range from -20°C to +85°C (-40°F to 185°F), making it suitable for outdoor and industrial environments where temperature fluctuations are common.
With a total travel of 1.6 mm (±0.3 mm typical) and an operating force of 4 N (±2 N), the IRR3S492 ensures precise and repeatable switching action. The switch achieves a mechanical life of 1,000,000 cycles, providing long-term durability for continuous industrial use.
The switch features solder lug terminals for secure electrical connections and a flat round actuator designed for optional marking and illumination. Its 3 mm panel thickness (max) and 0.8 Nm max. torque for nut installation ensure compatibility with standard panel mounting systems.
