Magnetic Proximity Sensors (Reed) MP2018 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*: 6.35 mm – 17.8 mm (0.25” – 0.7”) Environmental Specifications Vibration 20 g 10 Hz to 1 kHz (MP201801) 20 g 10 Hz to 55 Hz (MP201802) 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.
