Langir is now ROHS, ISO 9001:2008, CE, REACH, CB and CCC certified

Mechanical switches are used in almost every field from petrochemical to pharmaceutical industries. A majority of the process control applications rely on setting the physical variables such as pressure and temperature correctly which is done using mechanical switches. Even though these switches offer advantages such as simplicity and resistance towards electromagnetic disturbances, they still suffer from mechanical limitations. Mechanical switches are no way near to the ideal switches. There are certain factors that avoid reaching the desired accuracy. These and other problems have pushed companies and manufacturers to switch to piezo and anti – vandal switches.

Langir is a company that designs and manufactures piezo and anti-vandal switches in various types. Established in 2009, Langir is now ROHS, ISO9001:2008, CE, REACH, CB and CCC certified and exports to many regions across the world. The company specializes in producing switches with mounting holes ranging from 8mm to 30mm. As the name suggests piezoelectric switch works on the principal of piezoelectric effect. The advantage of piezo switches is that they have no moving parts – they only comprise of a front plate with a small deformation and a piezo element. No moving parts means no wear and tear. This further extends their lifetime and can be used for 10s of millions of cycles. Another advantage is that these switches can be made weatherproof by completely sealing them. They are made of stainless steel and therefore resistant to vandal damage. The anti-vandal switches find application in kiosk applications, ticket dispensers and other industrial processes. Like piezo switches these also offer options like illumination, long life and sealed. Piezo produces a single “on” pulse which can be varied with pressure. With some additional circuitry this pulse can be changed to “off” state.

Switches produced by Langir comply with the RoHS directive (restriction of use of certain hazardous substances in electrical and electronic equipment) which means that the amount of lead, cadmium and mercury is within safe limits and therefore safe for the environment. The company accepts small trial orders. Its automated processes and large production capacity makes it capable of accepting OEM too. Langir offers widest range of switch products in the market. The company has its own R&D departments and all the designing, fabrication and production is done in Langir’s state-of-the-art in-house facility. All the stages in production are controlled by Langir from raw material to its transformation into finished products. Langir also complies with other standards including IP69K protection and UL94-V0 plastics flammability standards.

Apart from piezo and anti-vandal switches Langir also manufactures alarms, Capacitive switches circuit protection, indicators, Bus Bars, DIN Rail support, Mounting and brackets, circuit breakers for solar generation and capacitive switches.

Langir’s both piezo and anti-vandal switches are perfect solution for use in heavy industries. Anti-vandal switches are available in off (on) configuration and option of domed, high or flat actuators.   These piezo electric switches can be combined with front plates made of stainless steel or aluminium making them highly apt for very rough environments. Langir is further expanding its production to keypads and touch switches or capacitive switches.
