Abstract
A portable data terminal is provided having a main housing including electronic circuitry for receiving data via an operator input. A keypad module is selectively securable into a receiving area of the main housing. A coupling provides an electrical connection between the keypad module and the electronic circuitry within the main housing when the keypad is secured into the receiving area. The coupling maintains an environmental seal between the receiving area and an interior of the main housing in which the electronic circuitry is located.
