Ideal for applications requiring tactile feedback and high durability.
The APEM Panel Switches ISR3SAD900 is a high-reliability, sealed autoswitch engineered for extreme industrial environments. Featuring IP67 protection against dust and water immersion, this switch delivers exceptional durability with 500,000 cycles of electrical operation under full load. Its wide temperature range (-40°C to +85°C) and robust construction ensure consistent performance in challenging conditions, while tactile feedback and compact design make it suitable for applications where precise, reliable switching is critical.
The ISR3SAD900 is engineered for extreme environmental conditions. With IP67 sealing against dust and water immersion, it maintains functionality in wet or dusty settings. Additional silicone boot protection shields against frost and abrasion from sand, ensuring long-term reliability in harsh outdoor or industrial environments. It also withstands 100 g shocks and 10-500 Hz vibrations at 10 g, meeting IEC 512-4 standards for robustness.
This switch supports a maximum current of 400 mA at 32 VAC and 100 mA at 48 VDC for resistive loads. It features an initial contact resistance of 50 mΩ max and an insulation resistance of 1 GΩ min at 500 VDC, ensuring stable electrical connections and minimal signal degradation. The dielectric strength of 1,000 Vrms guarantees safe operation under high-voltage conditions.
The ISR3SAD900 delivers 500,000 cycles of electrical life at full load, with a total travel of 1.7 mm (±0.3 mm). Its operating force of 4 N (±3 N) ensures smooth actuation, while the tactile feedback provides immediate user confirmation. The switch is designed for low-level or mechanical life of 1,000,000 cycles, making it suitable for high-use applications.
Available with solder lug bushing or threaded bushing options, the ISR3SAD900 features a compact, lightweight design with a behind-panel depth of 13 mm. The black bezel and silver (gold-plated) contact materials ensure durability and corrosion resistance. Mounting is straightforward with a panel thickness of 1.5 mm (min.) to 4 mm (max.), and it supports soldering up to 300°C for 3 seconds.
