Explore performance details, construction highlights, applications, and technical information in one clear overview.
The APEM Panel Switches ILR3SAD2 are robust, high-reliability autoswitches designed for demanding industrial environments. These switches feature IP67 sealing for dust and water resistance, operate within -40°C to +85°C temperatures, and deliver 1,000,000 cycles of mechanical life with a 4 N operating force. Ideal for applications requiring precise control in harsh conditions.
The APEM Panel Switches ILR3SAD2 are high-performance, momentary pushbuttons engineered for industrial automation systems where reliability and environmental resilience are critical. With a standard IP67 rating for dust and water protection, these switches maintain consistent operation across extreme temperatures ranging from -40°C to +85°C. The product delivers exceptional durability through 1,000,000 mechanical cycles and a low contact resistance of 50 mΩ max, ensuring reliable performance in demanding applications such as heavy machinery, process control systems, and electrical panels where continuous operation is essential.
The ILR3SAD2 switches are engineered to withstand harsh industrial conditions. With an IP67 rating (standard models), they provide complete protection against dust ingress and immersion in water up to 1 meter depth. Additionally, the switches meet stringent environmental standards including shock resistance (100 g per IEC 512-4, test 6c), vibration resistance (10-500 Hz at 10 g per IEC 5), and salt spray resistance (IEC 512-6, test 11f). This ensures reliable performance in marine, outdoor, and high-contamination environments.
Designed for precise electrical control, the ILR3SAD2 delivers low contact resistance (50 mΩ max) and operates within a 2 A 24 VDC current rating for resistive loads. The switches support 200,000 cycles under these conditions, making them suitable for applications requiring frequent switching without degradation. The 1,000,000 mechanical life cycles ensure long-term reliability even in high-traffic environments.
The 1.7 mm total travel (±0.3 mm) provides consistent actuation while the 4 N operating force ensures user-friendly operation without excessive effort. Tactile feedback enhances user experience, and the flat round actuator allows for optional marking to meet specific application needs.
The ILR3SAD2 operates within a wide temperature range (-40°C to +85°C), accommodating extreme environmental conditions. With a dielectric strength of 1,000 Vrms and insulation resistance of 1 GΩ min. at 500 VDC, the switches maintain electrical safety even under high-voltage stress. The switches are also rated for 100 g shock resistance and 10-500 Hz vibration resistance, ensuring resilience in mobile or dynamic industrial settings.
