L25 Series Large-Size Vandal-Resistant Switch
Langir offers an extensive catalog of anti-vandal switches available in multiple functionalities, designs, and sizes, including large models with a 25-millimeter cutout. One such model is the L25 Series Large Anti-Vandal Switch.
The L25 Series has a diameter of 25 millimeters and can be installed on panels with a thickness of 1 to 10 millimeters for momentary switches and 1 to 12 millimeters for latching switches. Its body height ranges from approximately 30 to 40 millimeters, depending on the function.
It features a flat head with multiple lens options, including dot illumination and ring illumination. As usual, these illumination styles can be customized in specific colors such as red, orange, yellow, white, green, and blue. All LED colors have a lifespan of forty thousand hours and are available in multiple voltage options, from 3V up to 220V.
If you are concerned about the illumination size, note that opting for dot illumination reduces the total diameter by approximately 9 millimeters, while ring illumination reduces it by about 15 millimeters.
Regarding the material composition of the actuator and switch body, the L25 Series can be designed and manufactured from either stainless steel or anodized aluminum. Its base, on the other hand, is specially made from PA, commonly known as nylon.
Regardless of the material chosen, Langir guarantees that the L25 Series Large Anti-Vandal Switch can withstand damages from daily use, especially if installed outdoors.
It has an ingress protection rating of IP65, making it both dustproof and waterproof. While there are limitations to its water resistance, the L25 Series excels in resisting unintentional impacts. It can withstand external mechanical forces of up to ten joules, supported by an impact rating of IK10. For optimal performance, it is recommended to install the L25 Series in an environment with an operating temperature range of -20°C to 55°C, which is typically easy to achieve outdoors.
In terms of electrical specifications, the L25 Series Large Anti-Vandal Switch operates with a maximum switch rating of 5A/250VAC. It is available in several function options, including momentary and latching, both in 1NO1NC and 2NO2NC configurations.
The L25 Series Large Anti-Vandal Switch is the best choice if your primary requirement is a large-sized switch that is both durable and reliable.
At Langir, all our anti-vandal switches are tested and certified to meet your quality requirements.
