Opto-Electronic Actuator
ITT Aerospace Controls’ patented Opto Electronic Actuator (OEA) uses optical, non-contact, position sensing with solid state switching and incorporates an electrically isolated output shaft.
The Opto-electronic switches and a solidstate H-bridge motor drive replace the older electromechanical position sensing and motor drives (relays and micro-switches) used in other typical actuator designs. The Opto Electronic actuator’s Isolated Output Shaft eliminates the possibility of electrical energy being passed through the output shaft and creating a safety hazard.
