The APEM Panel Switches IRR3S4B2L0B is a high-reliability, sealed autoswitch engineered for industrial environments where durability and precision are critical. With an IP67 rating for dust and water resistance, this switch maintains consistent performance in challenging conditions such as salt spray exposure. Its tactile feedback mechanism provides immediate user confirmation during operation, while the flat round actuator design allows for optional marking to enhance identification in complex control panels. The switch supports a maximum current of 5 A at 250 VAC with a mechanical life of 1,000,000 cycles, making it ideal for applications requiring frequent switching without degradation.
The IRR3S4B2L0B delivers reliable electrical operation with a maximum current rating of 5 A at 250 VAC for resistive loads. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring long-term performance in high-frequency applications. The switch features an initial contact resistance of 100 mΩ max and dielectric strength of 750 Vrms between terminals, with 2,000 Vrms between terminals and frame for robust electrical isolation.
Engineered for extreme conditions, the switch meets IP67 standards for dust and water resistance, with salt spray resistance per IEC 512-6 test 11f. The operating temperature range spans -20 °C to +85 °C (-40 °F to 185 °F), allowing it to function reliably in both cold and hot industrial environments. This resilience ensures consistent performance without degradation in harsh settings.
With a mechanical life of 1,000,000 cycles and a total travel of 1.6 mm (±0.3 mm), the switch maintains precise operation over extended periods. The operating force of 4 N (±2 N) ensures smooth actuation, while the screw version supports up to 4 A continuous current. The switch's robust construction, including a 3 mm panel thickness, ensures structural integrity under demanding conditions.
The switch features a standard black bushing bezel with silver contact materials (gold-plated for corrosion resistance). Its flat round actuator design accommodates optional marking for enhanced identification, while the central lens allows for blue LED illumination. The solder lug terminals support reliable connections at a maximum soldering temperature of 320 °C for 3 seconds.
