L22B Series Big Current Anti Vandal Switch

When it comes to switches that can handle not just a rough environment but also big current, Langir’s series of big current anti vandal switches is your best choice. Depending on your area, but if it would fit a 22-millimeter switch, then the L22B Series might be the one you’re looking for.

The L22B Series Big Current Anti Vandal Switch has a flat actuator and a quick connect terminal option that measures approximately 6.35 millimeters by 0.8 millimeters. It has a varying body height depending on its function and terminal option. For momentary, the L22B Series may vary in height from 22 to 26 millimeters, approximately. For latching function, this series may vary in size from around 28 millimeters to 32 millimeters, approximately.

As it is designed to handle big current, the L22B Series comes in different maximum switch ratings to best fit your needs. If using Alternating Current Voltage, options start at 2.5A up to 21A/250 VAC, 125VAC. On the other hand, if using Direct Current Voltage, the L22B Series can be made available with maximum switch ratings of 0.6A/125VDC and 0.3A/250VDC.

In terms of resistance to current flow, the L22B Series has a maximum contact resistance of 25 milliohms and a minimum of 100 milliohms insulation resistance. Its dielectric strength varies depending on parts and terminals. Additional information about the L22B Series’ shock and vibration resistance can be found in detail under the technical data presentation or from Langir’s catalog.

If not used or loaded with electrical current, the L22B Series can last up to 2 million cycles, otherwise, this series can only last up to 50 thousand cycles of electrical life.

As to what makes up the L22B Series, it has both its actuator and body made from stainless steel. Langir has always adhered to high-quality materials, that is why it is not surprising that the L22B Series can withstand usual wear and tear, primarily because of its levels of protection—IP65 and IK09.

With these levels of protection, you can be confident to install the L22B Series almost anywhere, may it be for public use or indoor use. Dust, water, and even unintended mechanical impact of less than ten joules will not damage the switch.

When it comes to customization, the L22B Series will not disappoint you. If you want some emphasis for your switch, then it might be helpful to have it customized with dot or ring illumination. For dot illumination, it will take about 9 millimeters of the switch’s whole diameter. Both of these illumination style options come in different colors including red, green, yellow, orange, blue, and white with an approximate lifetime of 40,000 hours. If the base voltage is your concern, then increasing it to your required voltage rating is also possible.

There’s no better option than the L22B Series Big Current Anti Vandal Switch when it comes to handling high current ratings. Not only it is certified and compliant, but it also offers flexibility to the user.
