Magnetic Proximity Sensors (Hall Effect) MP1021 Sensors Digital Hall-effect position sensor in low-profile flange-mount housing Description The MP1 Series sensors are one-piece non-contact solid-state position sensors. The sensors operate through the use of Hall Effect technology with magnetic fields generated by permanent magnets. They provide a sinking current output. Features Typical Applications Solid state reliability Door position & interlock Flange-mount housing Limit switch Stable output over operating temperature range Flow/speed Compatible with unregulated power supply Home security Open collector (NPN) output can be used with bipolar or CMOS Pedal switch logic circuits with suitable pull-up resistor North pole sensitive Unipolar device (MP102101, MP102102, MP102103) Latching versions available (MP101404, MP102105, MP102106) RoHS compliant IP67 Environmental Specifications Operating Temperature -40 C to 85 C (-40 F to 185 F) Storage Temperature -40 C to 85 C (-40 F to 185 F) Ingress Protection IP67 Electrical Specifications Operating Supply Voltage 4.5 to 24 VDC Supply Current 5 mA typ., 12 mA max.
