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
sensor
• Digital,latching or programmable
analog types available
• Medium, high or programmable
sensitivities
• Three-wire (voltage output) or twowire (current output) versions

1. Add capacitor Cn as shown, close for the sensors for transient suppression if required.
• High switching speed up to 10kHz
• Long life; up to 20 billion operations
• Operates in static or dynamic
magnetic field
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
Notes:
Rpu = 12Vdc/10mA = 1.2

Notes:
1. As long as Tj (Junction Temperature) is not exceeded. It is recommended to operate within the normal Operate Supply Voltage of +24Vdc maximum.
Operating beyond Absolute Ratings may cause permanent damage to the Hall IC.
2. Preprogrammed by Littelfuse or Customer pending agreement.
3. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse.
