Abstract
A method for manufacturing a sensor for a motor vehicle. The method includes placing a sensor core in a lower indentation of a mold; the sensor core having a metal lead frame, including connection pins and lateral retention members, and an integrated circuit, including at least one measurement cell and being overmolded on a support zone of the metal lead frame so the lateral retention members and the connection pins are exposed, and an electrically conductive terminal on each connection pin; placing a magnet in line with the overmolded integrated circuit; placing two lateral indentations of the mold on either side of the magnet and the integrated circuit so the lateral indentations retain the lead frame in the vicinity of the lateral retention members; overmolding the integrated circuit, the magnet and part of the lead frame to allow the free end of the terminals to project; and removing the mold.
