ABSTRACT:
To facilitate assembly and provide for high-level output from a deceleration sensor which provides, inherently, only very low level output, an evaluation circuit, such as an amplifier structure, is connected immediately adjacent the deceleration sensor on a common metal plate, interconnected thereby by bonding wires, the common plate having connecting pins (18) passing therethrough for connection to a standard plug-and-socket connector; the evaluation circuit and the deceleration sensor are enclosed within a common sealed housing, so that both the deceleration sensor (12, 12') as well as the evaluation circuit (16, 17) are sealed against ambient influences, preferably retained within a high-viscosity fluid, such as insulating oil. All elements can be located on one side of the housing, in which a standard T5 transistor housing is suitable; or the deceleration sensor may be located on the other side of the metal plate (10) from the evaluation circuit, in which case a plastic housing can be used, only the deceleration sensor being secured to the metal plate by a metal housing cap, sealed to the metal plate.
