Explore performance details, construction highlights, applications, and technical information in one clear overview.
The APEM Panel Switches ILR3PAD2 are robust, sealed autoswitches designed for demanding industrial environments. With IP67 sealing, 1,000 Vrms dielectric strength, and operation across -40°C to +85°C, these switches ensure reliable performance in harsh conditions. Ideal for applications requiring high mechanical durability and electrical safety.
The APEM Panel Switches ILR3PAD2 are precision-engineered autoswitches designed for extreme industrial environments. Featuring IP67 sealing, these switches deliver exceptional durability with a dielectric strength of 1,000 Vrms, operating reliably across a temperature range of -40°C to +85°C. The robust construction includes a 1.7 mm total travel, 4 N operating force, and gold-plated silver contacts, ensuring long-term performance in high-vibration, high-shock applications. With a mechanical life of 1,000,000 cycles and compatibility with resistive loads up to 2 A at 24 VDC, the ILR3PAD2 provides a reliable solution for critical control systems where environmental resilience and electrical safety are paramount.
The ILR3PAD2 supports 2 A current with 24 VDC resistive loads, offering 200,000 cycles of operation. Gold-plated silver contacts ensure low initial contact resistance (50 mΩ max) and high insulation resistance (1 GΩ min. at 500 VDC). The switches operate with a 4 N force requirement and feature a normally open (NO) electrical function.
Engineered for extreme conditions, the ILR3PAD2 withstands shocks up to 100 g (IEC 512-4, test 6c) and vibrations from 10-500 Hz at 10 g (IEC 512-4, test 6d). Salt spray resistance (IEC 512-6, test 11f) and IP67 sealing ensure reliable performance in harsh industrial settings, including marine or high-moisture environments.
With a total travel of 1.7 mm (±0.3 mm), the ILR3PAD2 delivers precise actuation with tactile feedback. The switches feature a flat round actuator for optional marking and a 1.5 Nm max. torque for secure mounting with plastic nuts (U4248) or metal nuts (U166).
Ideal for industrial control panels up to 10 mm thickness, the ILR3PAD2 is designed for applications requiring high durability, such as manufacturing equipment, automation systems, and machinery where environmental resilience and long operational life are critical.
