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.
