Featuring IP67 sealing, tactile feedback, and a flat round actuator for optional marking, this switch delivers reliable operation in harsh environments with a 1,000,000-cycle mechanical life and 5 A 250 VAC rating. Ideal for demanding electrical systems requiring high durability and environmental resilience.
The APEM Panel Switches IRC3S4B2L0B is a high-reliability microswitch autoswitch engineered for industrial environments. This switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in challenging conditions. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC current rating, it meets stringent requirements for durability and performance in applications where environmental resilience and long-term reliability are critical.
The IRC3S4B2L0B delivers precise electrical performance with a maximum initial contact resistance of 100 mΩ and a dielectric strength of 750 Vrms between terminals. It supports 5 A 250 VAC loads with 50,000 cycles for resistive applications and 25,000 cycles for inductive loads, ensuring reliable operation under varying electrical conditions.
Engineered for extreme environments, this switch achieves IP67 protection against dust, water, and salt spray (IEC 512-6, test 11f). The operating temperature range spans -20 °C to +85 °C (-40 °F to 185 °F), making it suitable for outdoor installations and harsh industrial settings without compromising performance.
With a mechanical life of 1,000,000 cycles and a total travel of 1.6 mm (±0.3 mm), the IRC3S4B2L0B maintains consistent performance over extended periods. The screw version supports up to 4 A current, while the flat round actuator provides tactile feedback for user confirmation during operation.
The switch features solder lugs for secure terminal connections and a 3 mm panel thickness (max). It is designed for both illuminated and non-illuminated operation with a blue LED for visibility, and the flat round actuator allows for optional marking to enhance identification in complex systems.
