ABSTRACT:
The invention provides a sensor for detecting impacts from, for example, a hockey puck striking a target apparatus embodying the sensor. The sensor uses a thin brass disc to which is secured a piezoelectric ceramic disc. In one embodiment an insulating disc having an electrically conductive element passing therethrough is held against the ceramic disc. In another embodiment a plastic spring clip carries an electrically conductive element at one end in contact with the ceramic disc. A wire is soldered to the brass disc and another wire is soldered to the electrically conductive element. The sensor may be incorporated into a spring biased sensor assembly which is positioned adjacent a medium that is expected to receive impact blows. The sensor will detect such blows and provide, consistently, a signal to indicate reception of the blows. The sensor can withstand a vast multitude of impacts without failure as the wires are not physically loaded.
