Explore performance details, construction highlights, applications, and technical information in one clear overview.
The APEM Panel Switches ISR3SAD500UL is a robust, sealed, and tactile feedback switch designed for demanding industrial environments. With an IP67 rating, operation across -40°C to +85°C, and electrical life of 500,000 cycles, this switch ensures reliable performance in harsh conditions. Ideal for applications requiring high durability and resistance to shock, vibration, and environmental factors.
The APEM Panel Switches ISR3SAD500UL is a high-reliability, compact switch engineered for industrial use in extreme environments. Featuring an IP67 sealed design, this switch provides exceptional protection against dust, water, and corrosive elements while maintaining precise tactile feedback and robust mechanical performance. Its ability to withstand shock, vibration, and temperature extremes from -40°C to +85°C ensures consistent operation in challenging industrial settings without compromising safety or functionality.
Engineered for extreme conditions, the ISR3SAD500UL maintains performance in harsh environments. Its IP67 rating ensures complete dust and water resistance, while shock resistance (100g per IEC 512-4, test 6c) and vibration tolerance (10-500 Hz at 10g per IEC 512-4, test 6d) make it suitable for industrial machinery, automotive, and marine applications. The switch also passes salt spray testing (IEC 512-6, test 11f), ensuring long-term reliability in corrosive settings.
The switch delivers precise electrical characteristics with a maximum contact resistance of 50 mΩ and a dielectric strength of 1,000 Vrms. It supports a maximum current of 400 mA at 32 VAC or 100 mA at 48 VDC for resistive loads, ensuring efficient operation without overheating. The insulation resistance of 1 GΩ min. at 500 VDC guarantees stable electrical isolation even under high-voltage conditions.
With a total travel of 1.7 mm (±0.3 mm) and an operating force of 4 N (±3 N), the switch provides smooth, consistent operation. Its mechanical life of 1,000,000 cycles ensures longevity, while the threaded bushing models allow secure mounting in tight spaces. The switch also supports soldering up to 300°C for 3 seconds, facilitating reliable installation in high-precision systems.
The ISR3SAD500UL operates within a temperature range of -40°C to +85°C, making it ideal for both cold and hot industrial environments. Its compact design (panel thickness: 1.5 mm to 4 mm) and tactile feedback ensure user-friendly operation without compromising durability. The switch is designed for normally open (NO) electrical functions, providing precise control in critical applications.
