V19 Series Metal Anti Vandal Switch

The V19 Series is part of Langir’s extensive line of metal anti-vandal switches. This is another one of Langir’s heavy-duty switches with its body made of high-quality material. It’s ideal for both indoor and outdoor use where there’s a lot of risk of damage. To achieve optimum efficiency, the V19 Series must be installed in an environment that meets its requirements.

The V19 Series Metal Anti Vandal Switch is extensively certified, offering a maximum switch rating of 2A/48VDC, with a hole diameter of 19 mm, and a multiple function option of either momentary or 1NO.

This series offers a variety of choices when it comes to its material type. Aside from the usual stainless steel material, the V19 Series is also available to be made from anodized aluminum,  nickel-plated brass, and gold-plated brass. It has an ingress protection of IP65 and an impact protection of IK09.

An IP rating of this level ensures total protection against contact, foreign objects, and even dust. When it comes to its waterproofness, it may not have maximum protection, but it can withstand damage that may possibly be due to water coming from different directions projected by a 6.3-millimeter nozzle.

This series has a remarkably higher protection when it comes to external mechanical impacts with its IK09 rating. A 10 joules of impact will bear no damage to the V19 Series. This is roughly equivalent to a 5-kilogram mass dropped from a free fall height of 200 millimeters or 0.20 meters.

This series comes with three different actuators. Your options include a flat actuator, high, or a domed actuator. All these can be laser-etched to meet your graphical needs.

The V19 Series allows you to work flexibly with its multiple terminal options. When working with higher current ratings, the V19 Series with a solder terminal lets you create a better connection with better dissipation. However, it may not be an ideal solution for large production runs but can work great when used accordingly. Meanwhile, the V19 Series with screw terminal works best when you are working with narrow wire gauges.

A mechanical life of 1,000,000 cycles can be enjoyed with the V19 Series operated without load, while an electrical life of 200,000 cycles can be expected from this series when run with full rated current. 

An operation temperature around -20 °C to 55 °C is highly suggested when placing this series in its right working environment.

The significance of knowing the features above about the V19 Series holds equally well as knowing the contact resistance of this series which is 50 mΩ Max. This can help to detect the risk of fretting corrosion of contacts and in diagnosing and preventing contact corrosion as early as possible. This calculation must be understood in order to guarantee that the contactor make/break contacts are in good working order.

The insulation resistance and dielectric strength of the V19 Series Illuminated Anti Vandal Switch are also useful features. It has a minimum insulation resistance of 1000 mΩ and dielectric strength of 2,000 VAC, which you may find significant in the future especially when testing for damaged insulation.

The aforementioned features make the V19 Series Metal Anti Vandal Switch a popular vandal-resistant switch, especially when you are looking for a heavy-duty one. It can withstand damage that may be caused by constant use, exposure to moisture, and unwanted impacts.
