MPL 500 Series switches offer pressure, vacuum, and differential sensors, sensitive to as low as 0.05 in/H 2 O. Air Pressure Switch that activates between 120-125 knots. 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.Electrical:Diaphragm material can be selected for the operating medium, temperature range, and other parametersActuation point can be moderately adjusted by the designerDesigned for low current and logic applications ( LED indicators, solid state relays)10 to 20mA loads ensure reliable switching (Varistor or R-C snubber recommended for inductive loads)Heavier loads require the use of interface devices such as solid state relaysFeatures an integral triacTerminals:NEMA 0.020"" x 0.187"" male tabs are standardLow-profile terminals for 18-22 gage wireOptional bifurcated terminals accept 0.020"" x 0.187"" or 0.020"" x 0.110"" female quick disconnectsTerminals are available for printed circuit board mounting.Custom applications requiring elongated terminals, tinning, and custom wiring can also be accommodated.Leakage:The diaphragm functions as both sensor and sealDynamic applications, the diaphragm provides an adequate sealStatic applications, a secondary internal gasket will ensure a near bubble tight seal
