Alps has developed the HGPRDT Series latch 2-phase output type magnetic sensor for use in automotive equipment, supporting an operating temperature range between -40°C and +140°C, and voltages up to 30V.

The integrated circuit inside the HGPRDT Series was designed in-house at the Sendai R&D Center (Sendai, Miyagi Prefecture). The Sensors houses two sensing elements, allowing detection of rotation speed and direction at the same time.
