Numerous process control applications depend on pressure switches to operate reliably. To convert a physical pressure differential into an electrical signal a mechanical switch inside is used.
Microprecision Electronics SA in Vouvry, Switzerland is now offering a new variation of its MP500 sealed subminiature micro switch for this type of application. Compared to the standard version with an actuating force of max 2.5N, the new MP520 has a lower actuating force of max 1 N. The differential force is only about 0.2 N. The differential travel of less than 0.05mm and a fast change over time of 5 ms is another important parameter for process applications.
The Series MP500 is UL61058 and EN61058 approved for a power rating of 250 AC/ 5A with an operating temperature between – 40°C and 105°C. Termination options are PCB pins, solder lugs or cable. To adapt to special applications, the actuators can be custom designed.
Microprecision Electronics SA is a manufacturer of industrial microswitches and LED indicator lights with manufacturing in Switzerland and the USA.
