Explore performance details, construction highlights, applications, and technical information in one clear overview.
The APEM Panel Switches ISR3SAD300 is a robust, sealed switch designed for demanding industrial environments. With IP67 sealing, 1,000 Vrms dielectric strength, and operation across -40°C to +85°C, it ensures reliable performance in harsh conditions. Ideal for applications requiring tactile feedback and high electrical life.
The APEM Panel Switches ISR3SAD300 is a high-reliability, threaded-bushing switch engineered for extreme industrial conditions. This compact, lightweight switch delivers exceptional durability with IP67 sealing, 500,000 cycles of electrical life at full load, and operation across a wide temperature range from -40°C to +85°C. Its tactile feedback ensures precise actuation, while the robust construction withstands shock, vibration, and environmental exposure. The switch supports both AC and DC loads up to 400 mA at 32 VAC or 100 mA at 48 VDC, making it suitable for critical control applications where reliability and longevity are paramount.
The ISR3SAD300 operates within a maximum current/voltage rating of 400 mA at 32 VAC for resistive loads and 100 mA at 48 VDC. It features a normally open (NO) electrical function and maintains an initial contact resistance of 50 mΩ max. The switch also provides 1 GΩ min. insulation resistance at 500 VDC, ensuring reliable electrical isolation.
Engineered for extreme conditions, the ISR3SAD300 withstands shock resistance of 100 g (IEC 512-4, test 6c), vibration resistance from 10 to 500 Hz at 10 g (IEC 512-4, test 6d), and salt spray exposure (IEC 512-6, test 11f). Its operating temperature range spans -40°C to +85°C, enabling reliable performance in both freezing and high-heat environments.
The switch delivers a total travel of 1.7 mm (±0.3 mm) with an operating force of 2 N. It supports 1,000,000 cycles for low-level or mechanical life and is designed for use with metal nuts (1 Nm max. torque) or plastic nuts (1.5 Nm max. torque). Soldering is possible up to 300°C for 3 seconds.
The ISR3SAD300 features IP67 sealing, protecting against dust and water immersion. This robust sealing ensures the switch remains functional in harsh industrial settings without requiring additional protective measures.
