55100 Miniature Flange Mounting Proximity Sensor
Description
The 55100 is a miniature flange mounting hall effect sensor 25.5mm (1.004”) x
11.00m (0.433”) and only 3.00mm (0.118”) high 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.

Notes:
1. Add capcitor
Cn
as shown, close to the sensor , 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;
Rpu = 12Vdc/10mA = 1.2kOhm

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.
