The APEM Panel Switches ISR3SAD920 is a robust, sealed autoswitch designed for demanding industrial environments. With IP67 sealing, 1 GΩ insulation resistance at 500 VDC, and 500,000 electrical life cycles, this compact switch ensures reliable operation across extreme temperatures (-40°C to +85°C) and harsh conditions.
The APEM Panel Switches ISR3SAD920 is a high-reliability, sealed autoswitch engineered for industrial applications requiring durability and precision. This compact switch features IP67 sealing to protect against dust and water immersion, 1 GΩ minimum insulation resistance at 500 VDC, and 500,000 electrical life cycles under full load. Its robust construction withstands extreme temperatures (-40°C to +85°C), shock resistance (100 g), and vibration (10-500 Hz at 10 g), making it ideal for use in environments where reliability and longevity are critical. The switch delivers tactile feedback and operates within a 1.7 mm total travel with 4 N operating force, ensuring precise control and minimal maintenance.
The ISR3SAD920 operates with a maximum current of 400 mA at 32 VAC and 100 mA at 48 VDC for resistive loads. It features a normally open (NO) electrical function and an initial contact resistance of 50 mΩ maximum, ensuring low resistance and efficient operation. The switch is rated for 1,000,000 cycles for low-level or mechanical life, providing long-term reliability in demanding applications.
Engineered for extreme conditions, the ISR3SAD920 withstands temperatures from -40°C to +85°C, shock resistance of 100 g (IEC 512-4, test 6c), and vibration resistance of 10-500 Hz at 10 g (IEC 512-4, test 6d). It also passes salt spray testing (IEC 512-6, test 11f), ensuring resilience in harsh industrial environments without compromising performance.
With a total travel of 1.7 mm (±0.3 mm) and an operating force of 4 N (±3 N), the ISR3SAD920 delivers precise control and tactile feedback. The switch supports a maximum torque of 1 Nm with metal nuts (U166) or 1.5 Nm with plastic nuts (U4248), ensuring secure installation in various mechanical setups.
The ISR3SAD920 features IP67 sealing, protecting against dust and water immersion. This robust sealing ensures the switch remains functional in wet or dusty environments, extending its operational life without requiring frequent maintenance.
