55250 Angular Displacement Sensor
Description
The Littelfuse 55250 Series of rotary absolute position sensors provide angular
measurement between 0 and 105 degrees with the option of a full 360 degrees
of movement. The internal design of the sensor uses non-contact magnetic Hall
Effect technology as opposed to more common wiper-based resistive products.
This unit is immune to the performance limitations of the wiper-based products
that are associated with mechanical wear or contamination.
The 55250’s package design commonly finds applications within all types of
vehicle and industrial segments. It has been designed to operate in the harsh
environments of the inudstrial and commercial vehicle and the sensor has an
operating temperature range between -40°C and 125°C. This unit incorporates
automotive grade EMI/EMC and reverse polarity protection and mates with a
Delphi type sealed connector.
