The APEM Panel Switches KRR21N09XX10 is a robust autoswitch designed for industrial applications. Featuring a unique rocker design, laser etched symbols, and options for IP68 or IP69K sealing, these switches provide reliable operation in extreme environments. With an insulation resistance of 1,000 MΩ min. at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz, they ensure high performance for demanding electrical systems.
The APEM Panel Switches KRR21N09XX10 are high-reliability autoswitches engineered for industrial environments where durability and precision are critical. Combining a unique rocker mechanism with advanced sealing options, these switches deliver exceptional performance across a wide temperature range (-40 °C to +85 °C) and resist harsh conditions including salt spray, vibration, and extreme humidity. Their robust construction, featuring a PA 6-6 case and brass terminals with silver plating, ensures long-term stability in demanding applications such as heavy machinery, marine systems, and outdoor industrial installations.
The KRR21N09XX10 delivers reliable electrical performance with a minimum insulation resistance of 1,000 MΩ at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz. These switches support 60 W 24 VDC loads with 10,000 operational cycles, ensuring consistent performance under high-stress conditions. The initial contact resistance remains below 10 mΩ max., minimizing power loss and heat generation during operation.
Engineered for extreme environments, these switches withstand salt spray exposure for 96 hours (IEC 512-6 standard) and pass vibration testing from 10-500 Hz. The optional IP68 or IP69K sealing provides exceptional protection against water ingress, dust, and corrosive elements, making them suitable for marine, outdoor, and high-humidity industrial settings.
Available with IP68 or IP69K sealing according to IEC 60529 and DIN 40050-9 standards, these switches offer robust protection for harsh conditions. The sealing ensures reliable operation in environments with high levels of moisture, salt, or particulate matter, extending the product's lifespan without compromising functionality.
Constructed with a PA 6-6 case and ABS bezel, the switches feature brass terminals with solid silver grain or silver plating (A or S) for optimal conductivity and corrosion resistance. The contact roller is nickel-plated brass, ensuring smooth operation and long-term reliability in high-traffic applications.
