Opto-Electronic Control Actuator System Component

Product catalog summary
Overview: ITT Aerospace Controls' Opto Electronic Actuator (OEA) is a patented device that utilizes optical, non-contact position sensing and solid-state circuitry. It features an electrically isolated output shaft to prevent electrical hazards. The actuator replaces traditional electromechanical components with optical switches and a solid-state H-bridge motor drive.
Key Features:
  • Patented Optical Switching and Output Shaft Electrical Isolation
  • Manual override without back driving the motor and gear train
  • 90º rotation capability
  • Compliance with FAR 25.981 and SFAR88
  • Endurance life of 100,000 cycles
  • EMI/EMC filtering
  • Over 25,000 units in operation globally
Specifications:
  • Actuator Type: Motor operated - Permanent Magnet
  • Mounting Interface: Conventional Four Bolt
  • Electrical Connector: As required
  • Supply Voltage: 28 VDC Nominal, 18 to 36 VDC Range
  • Current Draw: 0.5 amp running, 3.0 amp inrush at 28 VDC
  • Dielectric Strength: 1500 VAC
  • Position Control: 2x position limit and 2x position indication, all non-contact optical switches
  • Shaft Rotation: 90 degrees
  • Speed: 1.7 to 5 seconds over voltage range
  • Rated Torque: 25 in-lbs. (2.8 Nm)
  • Stall Torque: 75 in-lbs. (8.5 Nm)
  • Ambient Temperature: -65˚F to +165˚F (-55˚C to +74˚C)
  • Enclosure: 14 psig (1 bar) environmentally sealed
  • Weight: 1.33 lbs (.60 Kg) Maximum
  • Bonding Resistance: 1.5 milliohms maximum
  • Duty Cycle: Intermittent, 8 seconds operating, 12 seconds off

Opto-Electronic Control Actuator System Component-1

Key Features • Patented Optical Switching • Patented Output Shaft Electrical Isolation • Manual override feature, without back driving of motor and gear train • Endurance Life: 100,000 cycles • EMI/EMC filtering • Over 25,000 currently flying around the world ITT Aerospace Controls' patented Opto Electronic Actuator (OEA) uses optical, non-contact, position sensing with solid state circuitry and incorporates an electrically isolated output shaft. The Optical switches and solid-state H-bridge motor drive replace the older electromechanical position sensing and motor drive (relay 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.
