L19T Series Waterproof Anti Vandal Switch

Among Langir’s line of waterproof anti-vandal switches, the L19T Series comes in a remarkable feature. Not only it is waterproof, but it also has an incredible level of protection when it comes to external mechanical forces. As to what it does and what benefit it adds to the switch, you can learn more about it in the below specifications.

Knowing the switch’s maximum switch rating, which is at 3A/250 VAC, is very helpful in avoiding possible damage. It is important to note that switches of this rating should be used appropriately and should never exceed its limit. In terms of its function, the L19T Series comes in multiple options primarily momentary but with an option to go for an alternated one.

Physically, the L19T Series measures 22 millimeters in diameter. Its height is around 35 millimeters with a possible addition or difference of 1 millimeter.

It has a flat head which can also be customized in different illumination styles. Commonly, Langir offers dot and ring illumination options, but its new technology offers an actuator with power backlit symbol. For a more enhanced look, you can combine it with ring illumination, and for an even more enhanced look, you can add colors to it. 

If you decide to choose one, you have the option to go for white, red, yellow, green, blue, or a combination of the three LED colors, red, blue, and green. Amazingly, these LEDs have a life of approximately 40,000 hours–that’s equivalent to how many years even if used all throughout the day. To ensure maximum performance, and safety as well, it is best to know the right voltage of the LED you’re going to choose. These LEDs are available not just in its base voltages but also at higher ratings including 3.3V to 220V.

As mentioned a while ago, the L19T Series offers a remarkable feature. Not only does it come with an ingress protection rating of IP65, but it also has an incredible impact protection rating at IK10–the maximum rating so far. Aside from being waterproof, which is a major feature, external mechanical forces will not damage this switch unless it equates to more than 20 joules. 

This protection can be attributed to the kind of material the L19T Series is built on. From its actuator to its body, high-quality stainless steel can be used, or depending on your choice, you can also opt for an anodized aluminum. Its base, just like other anti-vandal switches of Langir, is made from PBT.

There are other helpful features of the L19T Series that you may be interested to know, just like its terminal option, contact and insulation resistance, operating temperature, its lifetime, and more, which you can learn from the presentation of its technical data.

Regardless, if the L19T Series Waterproof Anti Vandal Switch matches all your required specifications, then go for it. This series will do best at any place and condition especially with its incredible level of protection.
