Momentary 1NO1NC L16 Series 

The L16 Series is part of Langir’s extensive line of anti-vandal switches. It comes in both lighter and higher levels of protection compared to ordinary switches and makes a great option for use either indoors or outdoors. It is important that this type of switch be placed in the right working environment that meets its specifications.

The L16 Series is highly certified, offering an electrical rating of 3A/250 VAC, a diameter of 16 mm, panel cutout, and multiple function options to choose from including momentary 1NO1NC or 2NO2NC and latching 1NO1NC or 2NO2NC.

This series can be made from stainless steel, nickel-plated brass, or anodized aluminum with an option of protection between IP40 and IP65 which is paired with an IK rating of IK09.

The L16 Series with IP40 protection may not be the best if you’re looking for a dustproof and waterproof anti-vandal switch. The series’ protection to foreign materials is only limited to tools and wires that measure more than 1 millimeter, and it is not protected from liquids at all.

However, the L16 Series with an IP rating of IP65 allows you to enjoy an anti-vandal switch that has total protection against contact and total dust ingress. It may not be the best of all waterproof anti-vandal switches, but it guarantees protection from low-pressure water jets from any direction.

On the other hand, an IK09 rating ensures protection against 10 joules of impact which is approximately equal to the impact of a 5 kg mass dropped from 200 mm above the impacted surface.

The L16 Series also comes in several illumination style options including dot illumination, ring illumination, power backlit symbol, and a combination of ring illumination and power backlit symbol. An extensive illumination voltage option is what also comes with the L16 Series. You have the option to maintain its base voltage at 1.8V for the following LED colors: yellow, red, and orange, and 2.8V for white, blue, and green LED colors. Increasing the illumination voltage from 3.3V up to 220V is also possible.

The L16 Series just like the other L series allows you to work effectively with high current ratings with its solder lug type measuring about 2.0 by 0.5 millimeters.

This series comes with flat and high actuator options depending on your choice, with an option to have the head laser-etched. A pressure of about 3N to 5N is needed to register a keypress.

The L16 Series has a mechanical life of 200,000 cycles, an electrical life of more than 50,000 cycles, and works in an environment with a temperature of -20 °C to 55 °C. It has a contact resistance of 50 mΩ Max which may come helpful when diagnosing and preventing contact corrosion as early as possible, insulation resistance of 1000 mΩ Minimum, and dielectric strength of 2,000VAC, which can be helpful in checking for damaged insulation in the future.

All these features make the L16 Series a popular option for both indoor and outdoor use that may require light to heavy exposure to damage and moisture.
