MPL 500 Series switches offer pressure, vacuum, and differential sensors, sensitive to as low as 0.05 in/H2O. Their accuracy and reliability offer the designer an excellent general purpose low pressure to electric interface for monitoring and control applications. Miniature size and low cost make the 500 Series ideal for OEM applications.

MPL 500 is diaphragm-operated utilizing low stress deflecting contacts. Elimination of sliding or pivoting parts results in high reliability and long service life. Diaphragm material can be selected for the operating medium, temperature range, and other parameters. During the development of a specification, actuation point can be moderately adjusted by the designer. In production, a factory setting is required.

MPL 500, 501, 502, and 503 are single-setting models, available as pressure, vacuum, or differential pressure sensors.  MPL 504 offers two settings.  MPL 533 adds the capability to switch high current loads, utilizing an integral AC static switch (triac). No power source is required other than the AC load.
