The APEM Panel Switches IRR3S452L0Y is a robust, sealed autoswitch designed for industrial applications. Featuring IP67 sealing, tactile feedback, and a flat round actuator for optional marking, it operates reliably in harsh environments with a 1,000,000-cycle mechanical life and 5 A 250 VAC rating for resistive loads. Ideal for demanding electrical systems requiring high durability and environmental resilience.
The APEM Panel Switches IRR3S452L0Y is a high-reliability, sealed autoswitch engineered for industrial environments where durability and performance are critical. With an IP67 rating ensuring protection against dust and immersion in water, this switch delivers tactile feedback for precise operation and is suitable for both illuminated and non-illuminated applications. Its flat round actuator design allows for optional marking, while the screw version supports up to 4 A continuous current. The switch operates within a wide temperature range of -20 °C to +85 °C and features a mechanical life of 1,000,000 cycles, making it ideal for applications requiring long-term reliability in challenging conditions.
The IRR3S452L0Y operates as a Normally Open (NO) switch with a dielectric strength of 750 Vrms between terminals and 2,000 Vrms between terminals and frame. It supports a maximum current of 5 A at 250 VAC for resistive loads, with 50,000 cycles for function 7 and 25,000 cycles for function 8. Initial contact resistance is 100 mΩ max, ensuring low resistance during operation.
Engineered for extreme conditions, the switch meets IP67 standards for dust and water resistance, with salt spray testing compliant to IEC 512-6, test 11f. It operates reliably across a temperature range of -20 °C to +85 °C (-40 °F to 185 °F), making it suitable for outdoor and harsh industrial environments.
The switch features a total travel of 1.6 mm (±0.3 mm) and requires an operating force of 4 N ± 2 N. With a maximum torque of 0.8 Nm applied to the nut, it ensures secure installation without damage. The screw version supports up to 4 A continuous current, while the tactile feedback provides a distinct user response.
Constructed with a 3 mm (.118) panel thickness, the switch uses silver contact materials (gold-plated) and a black bushing bezel. The central lens design accommodates yellow LED illumination for optional marking, while soldering is rated at 320 °C max for 3 seconds.
