The APEM Panel Switches IRR3F4B2L0B is a robust, sealed autoswitch designed for industrial applications. With an IP67 rating, 1 GΩ insulation resistance at 500 VDC, and 1,000,000 cycle mechanical life, this switch ensures reliable performance in harsh environments. Ideal for high-reliability systems requiring tactile feedback and optional illumination.
The APEM Panel Switches IRR3F4B2L0B is a high-performance, sealed autoswitch engineered for demanding industrial environments. Featuring an IP67 rating for dust and water resistance, this switch delivers exceptional durability with a 1 GΩ minimum insulation resistance at 500 VDC and a mechanical life of 1,000,000 cycles. Its 1.6 mm total travel and 4 N operating force ensure precise actuation, while the tactile feedback and optional illumination provide clear user interaction. Designed for applications requiring high reliability and resistance to environmental stress, this switch meets stringent industrial standards without compromising on performance.
The IRR3F4B2L0B delivers reliable electrical performance with a 100 mΩ maximum initial contact resistance and 750 Vrms dielectric strength between terminals. It supports 5 A 250 VAC loads with 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring long-term stability in high-demand applications. The switch operates within a temperature range of -20°C to +85°C, making it suitable for extreme environmental conditions.
Engineered for harsh industrial settings, the IRR3F4B2L0B features an IP67 rating for dust and water resistance, validated by IEC 512-6 test 11f. This robust sealing ensures protection against salt spray and environmental contaminants, maintaining consistent performance in outdoor or marine applications without compromising reliability.
Constructed with a 3 mm panel thickness (max), the switch uses silver contacts (gold-plated) for superior conductivity and corrosion resistance. The central lens design allows for optional illumination with a blue LED, while the flat round actuator provides tactile feedback and space for optional marking.
With a total travel of 1.6 mm (±0.3 mm typical), the switch requires a 2 N operating force and delivers 4 N maximum torque for secure mounting. The screw version supports up to 4 A continuous current, while the 320°C soldering temperature ensures reliable assembly without damaging the switch's integrity.
