Electrically conductive housing for an electronic component, especially a deflection sensor and a security fence alarm system for use therewith

摘要

An electrically conductive housing completely envelops an electronic component so as to screen the electronic component from electromagnetic radiation whilst permitting movement of the electronic component relative to the housing when acted upon by an external force. According to a preferred embodiment, the electronic component is a deflection sensor or taut wire sensor for use in an electrical security fence, such that the sensor is completely shielded from the atmospheric effects and stray radiation.
