25mm Piezoelectric Sensor Switch

  • Easy to clean metal surface
  • Long life (50 million cycles)
  • Ring or Dot illumination
  • Sealed to IP68 or IP69K (switch mounted on panel)

Advantages

Langir piezoelectric sensor switches are based on a solid-state output allowing for a very long life expectancy (more than 50 millions cycles), ideal for demanding applications where reliability is most important. The flat actuation surface is completely closed, preventing the intrusion of liquids or other contaminants, perfect for surface cleaning required in the medical and food-processing industries. High performance sealing (IP68 and IP69K) is achieved due to the one-piece construction of the switch. No external power supply is required. The screw-machined metal housing construction and Langir’s vertical integration allow for the manufacture of a variety of shapes.

 Mechanics

A piezoelectric sensor is a device that generates an electrical charge in response to mechanical stress. It works on the principle of the piezoelectric effect, which is the ability of certain materials, such as quartz, to generate an electric charge when subjected to mechanical stress.

A piezoelectric sensor typically consists of a piezoelectric material sandwiched between two electrodes. When a force or pressure is applied to the material, it generates an electric charge proportional to the force’s magnitude. This charge can then be measured and used to determine the force or pressure being applied.

These piezoelectric sensor switches are used in various applications, including measuring weight, pressure, acceleration, and vibration. They are commonly used in industrial and automotive applications, as well as in medical devices and consumer electronics.
