The APEM Panel Switches ISR3SAD400UL is a robust, sealed autoswitch designed for demanding industrial environments. With IP67 sealing, 1,000 Vrms dielectric strength, and 500,000 cycles of electrical life, this switch ensures reliable operation in extreme conditions from -40°C to +85°C. Ideal for applications requiring high durability and resistance to shock, vibration, and environmental factors.
The APEM Panel Switches ISR3SAD400UL is a high-reliability, sealed autoswitch engineered for industrial applications where environmental resilience and long-term performance are critical. Featuring IP67 protection against dust and water immersion, this switch maintains consistent operation across extreme temperatures (-40°C to +85°C) and withstands harsh conditions including shock (100g), vibration (10-500 Hz), and salt spray exposure. Its robust construction, with a 1.7 mm total travel and 4 N operating force, ensures precise tactile feedback and reliable contact performance even under demanding electrical loads up to 400 mA at 32 VAC or 100 mA at 48 VDC.
Engineered to withstand extreme environmental conditions, the ISR3SAD400UL meets stringent IP67 standards for dust and water resistance. It also complies with IEC 512-4 tests for shock (100g) and vibration (10-500 Hz at 10g), ensuring reliable performance in harsh industrial settings. Salt spray resistance (IEC 512-6, test 11f) further enhances its suitability for outdoor or marine applications where exposure to corrosive elements is common.
The switch delivers precise electrical characteristics with an initial contact resistance of 50 mΩ max and a max current/voltage rating of 400 mA at 32 VAC or 100 mA at 48 VDC for resistive loads. Its dielectric strength of 1,000 Vrms ensures safe operation under high-voltage conditions, while the 500,000-cycle electrical life guarantees long-term reliability in demanding applications.
Constructed with a compact design (1.5 mm to 4 mm panel thickness), the ISR3SAD400UL features a 1.7 mm total travel (±0.3 mm) and 4 N operating force, providing smooth operation with tactile feedback. The switch supports 1,000,000 cycles for low-level or mechanical life, making it ideal for high-frequency switching applications without degradation.
The switch includes a silicone boot for additional protection against frost and abrasion by sand, enhancing its IP67 rating. This feature ensures long-term performance in cold environments and dusty conditions, while the sealed design prevents internal contamination and moisture ingress.
