21FW series single channel sensors, 23FW series triple channel sensors and the 5FW series magnet targets were originally created and specified for use on the Lockheed Martin Joint Strike Fighter aircraft. The ultra-high reliability and small profile of the hall effect sensors and targets, along with their enhanced resistance to electromagnetic interference and competitive cost, make these products ideal for many locations on an aircraft, or applications with severe shock, vibration, temperature and EMI environments.
