55310 Flat Pack Digital Hall Sensor

Description

The Littelfuse 55310 absolute position sensor provides a digital output signal

when activated by a magnet. The internal design of the sensor uses non-contact

magnetic Hall effect technology. This sensor is immune to the performance

limitations of the mechanical based products that are associated with

mechanical wear or contamination.

The 55310 package design commonly finds applications within all types of

vehicle and industrial segments and designed to operate in the harsh

environments, the sensor has an operating temperature range between -40°C

and 105°C. This unit incorporates automotive grade EMI/EMC and reverse

battery polarity protection, as well as commercial grade 20 AWG-TXL automotive

wire and the option of a Molex type sealed connector.
