Hall Effect Sensors Rotary Hall Sensor > 55250 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 55250s 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 -40C and 125C. This unit incorporates automotive grade EMI/EMC and reverse polarity protection and mates with a Delphi type sealed connector.
