ABSTRACT:
A sensor assembly for sensing the air-to-fuel mixture in an internal combustion engine, and a method of manufacturing it. The assembly comprises a premolded plastic panel which is adapted to receive a Kapton and a terminal strip stamping. The stamping is positioned over the Kapton on registry pins in the panel. Another panel is then injection molded over the stamping and Kapton, welding itself to the one panel. The stamping and Kapton are encapsulated without damage to the Kapton. Terminal strip bridges are then removed from the stamping and a resistor welded between two of the strips.
