The APEM Panel Switches ISR3SAD400 is a robust, sealed, tactile feedback switch designed for demanding industrial environments. With IP67 sealing, 500,000-cycle electrical life, and operation across -40°C to +85°C, this autoswitch ensures reliable performance in harsh conditions. Ideal for applications requiring high durability and compact design.
The APEM Panel Switches ISR3SAD400 is a high-reliability, compact autoswitch engineered for extreme industrial environments. Featuring IP67 sealing, this switch delivers exceptional durability with 500,000 cycles of electrical life at full load, operating reliably across a wide temperature range from -40°C to +85°C. Its tactile feedback ensures precise operation, while the robust construction withstands shock, vibration, and environmental exposure. Designed for applications where reliability and longevity are critical, the ISR3SAD400 provides a dependable solution for industrial control systems.
The ISR3SAD400 is engineered to withstand harsh industrial conditions. Its IP67 sealing ensures protection against dust and water immersion, while shock resistance (100g per IEC 512-4, test 6c) and vibration resistance (10-500 Hz at 10g per IEC 512-4, test 6d) make it suitable for demanding environments. Additionally, it passes salt spray testing (IEC 512-6, test 11f), ensuring long-term reliability in corrosive settings.
With a maximum current rating of 400 mA at 32 VAC and 100 mA at 48 VDC for resistive loads, the ISR3SAD400 delivers stable operation in low-power applications. The initial contact resistance remains below 50 mΩ, ensuring minimal voltage drop and efficient circuit performance. Its insulation resistance of 1 GΩ minimum at 500 VDC guarantees electrical safety and stability.
The switch features a total travel of 1.7 mm (±0.3 mm) with an operating force of 4 N (±3 N), providing precise and consistent actuation. Its mechanical life of 1,000,000 cycles ensures long-term durability, while the threaded bushing models allow for secure mounting in tight spaces. The switch also supports soldering up to 300°C for 3 seconds, facilitating reliable installation.
Operating across a wide temperature range from -40°C to +85°C (-40°F to 185°F), the ISR3SAD400 maintains performance in extreme conditions. This robust thermal range ensures consistent operation in both cold and hot industrial environments, making it ideal for applications where temperature fluctuations are common.
