Solid State Rotary Sensor

Our contactless rotary position sensors offers a direct replacement for obsolete contacting wire wound technology. With the use of on-board electronics, the sensor outputs can interface directly with air data computers and flight recorders. Options include single or dual channel for built in redundancy.
