These switches feature a unique rocker design, laser-etched symbols, and options for IP68 or IP69K sealing to ensure reliability in harsh conditions. With a current/voltage rating of 60 W 24 VDC and 150,000 mechanical cycles, they provide dependable performance for critical applications.
The APEM Panel Switches KRR21NXXXXXX represent a high-performance autoswitch solution engineered for extreme industrial conditions. Combining a unique rocker design with laser-etched symbols, these switches deliver exceptional durability and reliability through their robust construction and advanced sealing options. The product supports both illuminated and non-illuminated variants, with the ability to be sealed to IP68 or IP69K standards for protection against environmental hazards. This makes them ideal for applications requiring high mechanical life and resistance to vibration, salt spray, and temperature extremes.
The KRR21NXXXXXX switches operate within a current/voltage rating of 60 W 24 VDC, supporting up to 10,000 cycles for reliable electrical switching. With an initial contact resistance of 10 mΩ max and insulation resistance of 1,000 MΩ min at 500 VDC, these switches ensure minimal power loss and high electrical safety in demanding applications.
Engineered for harsh industrial environments, these switches withstand salt spray exposure for 96 hours (IEC 512-6), vibration resistance from 10 to 500 Hz, and temperature extremes ranging from -40 °C to +85 °C. The optional IP68 or IP69K sealing provides exceptional protection against water and dust ingress, making them suitable for marine, chemical, and outdoor installations.
Available with IP68 sealing for protection against water ingress or IP69K sealing for high-pressure and high-temperature environments, these switches meet stringent international standards. The sealing options ensure long-term reliability in applications where exposure to liquids, dust, or corrosive substances is a concern.
With a dielectric strength of 2,000 Vrms 50 Hz minimum, the KRR21NXXXXXX switches provide robust electrical isolation between terminals. The mechanical life of 150,000 cycles ensures extended service life, while the wide choice of colors and laser-etched symbols allow for customization to match specific system requirements.
