摘要： A position sensor and variable reluctance type controller interface circuit (10) is provided. The circuit (10) includes a position sensor (22) having an output terminal (OUT) and generating a position signal. A variable reluctance type controller (20), having an input bus (26), is electrically coupled to the position sensor (22) via a voltage divider circuit (24). The circuit (24) supplies a voltage differential output signal in response to the position signal to the input bus (26). A method of interfacing between the position sensor (22) and the controller (20) is also provided. The method includes generating a position signal. The reference voltage on the controller (20) is divided to an approximately fixed voltage level. The approximately fixed voltage level is supplied to a negative input terminal (INPUT−) on the variable reluctance type controller. The position signal is received on a positive input terminal (INPUT+) of the controller (20).

摘要： Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.
