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) Environmental Specifications Vibration 20 g 10 Hz to 1 kHz (MP201901), 20 g 10 Hz to 55 Hz (MP201902, M201903) Operating Temperature -40 C to 105 C (-40 F to 221 F) Storage Temperature -40 C to 105 C (-40 F to 221 F) Ingress Protection IP65 Electrical Specifications Typical Operating Time 1 ms Breakdown Voltage 200 VDC min.
