The Littelfuse 55250 series of rotary absolute position sensors provide angular measurement between 0 and 105 degrees with the option of a full 360-degree 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. Designed to operate in the harsh environments of the industrial and commercial vehicle, 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.
