Hall Effect Sensors
Rotary Hall Sensor > 55300
55300 Flat Pack Rotary Hall Sensor
Description
The Littelfuse 55300 Series of rotary absolute position sensors provide angular
measurement between 0 and 360 degrees. This unit is activated by a remote
magnet, thus allowing a larger stack up of mechanical tolerances that are not
feasible with the integral magnet version 55250. The internal design of the
sensor uses non-contact magnetic Hall effect technology with options of analog
or PWM output signals. This sensor is immune to the performance limitations of
the wiper based products that are associated with mechanical wear
or contamination.
The 55300 package design commonly finds applications within all types of
vehicle and industrial segments and designed to operate in the harsh
environments of the industrial and commercial vehicle, 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.
