## **Magnetic Proximity Sensors (Reed)** 

## **MP2019 Sensors** 

Reed based magnetic proximity sensor in plastic flange-mount package 

## **Description** 

The MP2 Series sensors are reed position sensors.  Normally open or closed contacts change states when a magnetic field is applied.  The sensors act as non-latching electrical switches. 

## **Features** 

## **Typical Applications** 

Contacts hermetically sealed for long life Door position & interlock Zero power consumption Limit switch Suitable for DC and AC circuits Flow/speed Flange mount Home security RoHS compliant Pedal switch IP65 Operate/Release Distances*: 10.16 mm – 22.86 mm (0.4” – 0.9”)
