Hall Effect Sensors Flange Mount > 55140 55140 Miniature Flange Mounting Sensor Description The 55140 is a small flange mounting hall effect sensor occupying only 3.22cm² (0.500”² ) board space with a choice of digital, or programmable analogue outputs. It is available as three-wire (voltage output) or two-wire (current output) versions. It’s case design enables screw or adhesive mounting and capable of switching up to 28Vdc and 20mA. It comes with a range of sensitivity, cable length and connector options. Features • Magnetically operated position • Vibration 50g max. @ 50-2,000Hz sensor • Shock 150g max. @ 11ms ½ Sine • Digital,latching or programmable • EMC to DIN 40839 (Consult analog types available Littelfuse) • Medium, high or programmable • Reverse/Over voltage protection Block Diagram sensitivities • Built in temperature compensation Two-wire Version • Three-wire (voltage output) or two- • Open Drain Output VDD wire (current output) versions Pin 1 (Red) Hall Current Switch Comparator Source Plate Cn Benefits Clock GND • High switching speed up to 10kHz • Unaffected by harsh environment Pin 2 (Black) • Long life; up to 20 billion operations • Customer selection of cable length • Operates in static or dynamic and connector type Notes: magnetic field 1. Add capacitor Cn as shown, close for the sensors for transient suppression if required. 2. Add pull-up resistor Rpu as shown for sinking output. The Rpu value should be calculated using your supply voltage while keeping the ON state current at a level below the maximum. Rpu = VDD/Io; Applications Rpu = 12Vdc/10mA = 1.2 • Position and limit sensing • Flow metering • RPM measurement • Angle sensing Three-wire Version • Commutation of brushless • Magnetic encoders VDD DC motors VDD Pin 1 (Red) Hall Rpu Switch Comparator Output Plate Cn Clock GND OUT Pin 2 Pin 3 (Blue) (Black) Dimensions Dimensions in mm (inch) Two-wire version illustrated. 23.00 (.906) 300 6.00 (11.81) Encapsulant excluded (.236) 6.35 NOM.
