MPL 4100: Low Pressure Momentary Switches

Introduction

MPL 4100 Series is an automatic reset pressure switch, using snap-dome technology for robust and accurate switching in a wide variety of applications.

MPL 4100 Series is designed for low-cost OEM application; MPL 4100 Series features a unique new calibration system which enables highly accurate settings from 10 to 650 PSI with lower hysteresis than conventional pressure switches.

Available pressure ports include straight copper tube or Schrader-fitting. Standard models provide push-on terminals for quick connection. Wire leads are also available to custom length in OEM quantities.

MPL 4100 Series is ideal for heat pumps, air conditioners, refrigeration, hydraulic fluid, water pressure and many other applications where isolation of the medium is required.
