L22B Series High-Current Vandal-Resistant Switch
For switches capable of withstanding harsh environments while handling high current, Langir’s series of high-current anti-vandal switches is the optimal choice. Depending on your region, if a 22-millimeter switch is suitable, the L22B Series may meet your requirements.
The L22B Series High-Current Anti-Vandal Switch features a flat actuator and a quick-connect terminal option measuring approximately 6.35 mm by 0.8 mm. Its body height varies based on function and terminal configuration. For momentary function, the height ranges approximately from 22 mm to 26 mm. For latching function, the height ranges approximately from 28 mm to 32 mm.
Designed for high-current applications, the L22B Series offers various maximum switching ratings to suit different needs. For alternating current (AC) voltage, options range from 2.5A up to 21A at 250VAC or 125VAC. For direct current (DC) voltage, maximum ratings include 0.6A/125VDC and 0.3A/250VDC.
In terms of electrical resistance, the L22B Series has a maximum contact resistance of 25 milliohms and a minimum insulation resistance of 100 milliohms. Its dielectric strength varies depending on the parts and terminals. Detailed information on shock and vibration resistance can be found in the technical data or Langir’s catalog.
Without electrical load, the L22B Series can endure up to 2 million mechanical cycles. Under electrical load, its electrical life is up to 50,000 cycles.
The L22B Series is constructed with both actuator and body made of stainless steel. Langir consistently uses high-quality materials, which is why this series offers durability against wear and tear, supported by protection ratings of IP65 and IK09.
With these protection levels, the L22B Series can be installed in diverse environments, whether for public or indoor use. It is resistant to dust, water, and mechanical impacts up to 10 joules.
The L22B Series offers customization options, including dot or ring illumination for enhanced visibility. Dot illumination occupies about 9 mm of the switch diameter. Both illumination styles are available in colors such as red, green, yellow, orange, blue, and white, with an approximate lifespan of 40,000 hours. Voltage adjustments to meet specific requirements are also possible.
For handling high-current ratings, the L22B Series High-Current Anti-Vandal Switch is an excellent choice. It is certified, compliant, and provides user flexibility.
