The APEM Panel Switches ISR3SADA20 is a robust, sealed autoswitch designed for demanding industrial environments. With IP67 sealing, 1,000 Vrms dielectric strength, and 500,000 cycle electrical life, this switch ensures reliable operation in extreme conditions from -40°C to +85°C. Ideal for applications requiring high durability and environmental resilience.
The APEM Panel Switches ISR3SADA20 is a high-reliability, sealed autoswitch engineered for industrial use in harsh environments. Featuring IP67 protection against dust and water immersion, this switch delivers exceptional durability with 500,000 cycles of electrical life at full load and 1,000 Vrms dielectric strength. Its operating temperature range of -40°C to +85°C (-40°F to 185°F) ensures consistent performance across extreme conditions, while the 1.7 mm total travel and 4 N operating force provide precise, tactile feedback for reliable operation. The switch’s compact design, with a panel thickness of 1.5 mm to 4 mm, and optional silicone boot for frost and abrasion protection make it suitable for applications where environmental resilience and mechanical robustness are critical.
The ISR3SADA20 excels in extreme environmental conditions with IP67 sealing, ensuring protection against dust and water immersion. It meets rigorous standards for shock resistance (100 g per IEC 512-4, test 6c) and vibration resistance (10-500 Hz at 10 g per IEC 512-4, test 6d). Additionally, it passes salt spray testing (IEC 512-6, test 11f), making it suitable for outdoor or marine applications where exposure to harsh elements is common.
This switch delivers reliable electrical performance with a maximum contact resistance of 50 mΩ and a dielectric strength of 1,000 Vrms. It supports 400 mA at 32 VAC and 100 mA at 48 VDC for resistive loads, ensuring compatibility with a wide range of industrial power sources while maintaining safety and efficiency.
Engineered for long-term mechanical stress, the ISR3SADA20 withstands 100 g shock resistance and 10-500 Hz vibration resistance. Its robust construction, including a satin chrome bezel and silver contact materials (gold-plated), ensures consistent performance even under demanding operational conditions.
The ISR3SADA20 is ideal for industrial control panels where environmental protection and mechanical durability are critical. Its compact size (13 mm behind panel depth), low operating force (4 N), and tactile feedback make it suitable for applications such as machinery control, automation systems, and equipment requiring high reliability in harsh environments.
