L22T Series Momentary 2NO2NC Anti Vandal Switch
One of Langir’s unique series of anti-vandal switches is the L22T Series Momentary 2NO2NC Anti Vandal Switch.
It has a maximum switch rating of 3A/250VAC, and a bushing diameter of 22 millimeters, panel cutout—ideal for a surface with a panel thickness of around 1 to 10 millimeters.
A flat head or a raised head are your two options for the L22T Series’ actuator. With a flat head, you can expect around 2 millimeter-sized button, while a raised head will measure around 3.90 millimeters.
Just like the other series, you have the option to have it illuminated. Whether you want a dot illumination or ring illumination, you can have it at Langir. Other options include a power backlit symbol or a combination of it and ring illumination.
The power backlit symbol alone will approximately measure 8.0 millimeters by 8.10 millimeters—almost half of the whole actuator. However, when combined with ring illumination, it will only measure around 6 millimeters by 6.4 millimeters. For dot illumination, it will measure around 9 millimeters in diameter.
If you have a specific color requirement, you may choose from Langir’s common list of LED colors including white, yellow, red, green, and blue, or a combination of blue, green, and red.
All these can be obtained with their base voltages at 1.8 volts @20mA for red and yellow, and at 2.8 volts @20mA for blue, green, and white, or increased from 3.3 volts or higher, up to 220 volts maximum.
As to what makes the L22T Series, it has a button and body made of either stainless steel or anodized aluminum, and a base made of PBT. Depending on availability, the L22T Series’ button and body color may be customized once it is made from anodized aluminum. It is always best to reach out to Langir to get detailed recommendations.
Langir always adheres to the highest standard. You can expect that the L22T Series will perform well even when placed outdoors where heavy use and inconsistent weather conditions may affect the switch. This is attributed to its ingress protection rating of IP65 and impact protection rating of IK09.
Although it has a high protection rating, it is still best to install this series in an environment where the temperature runs between -20 °C and 55 °C.
Meanwhile, when it comes to the technical data of the L22T Series, the following may come helpful.
If you are wondering how the L22T Series may react to current flow, especially if it touchesng another contact, it may be helpful to know thseries’ss’ contact and insulation resistance. It has a contact resistance of fifty milliohms at minimum, and an insulation resistance of one thousand milliohms at maximum. Additionally, in measuring the electrical strength of the L22T Series’ insulating material, it is best to know its dielectric strength which is at 2000VAC.
Without the flow of full current, the L22T Series can last up to 2 million cycles. This is shortened to up to 100 thousand cycles only when loaded with current.
If all these features meet your needs, then look no further than Langir’s L22T Series Momentary 2NO2NC Anti Vandal Switch.
