ITT Aerospace Controls’ Compact Actuator is a non-backdrivable rotary actuator using a permanent magnet DC motor with separate electro-mechanical switches for position limit and indication at each end of travel, eliminating the possibility of a latent failure.
Solid state circuitry is used in lieu of a conventional electro-mechanical directional control relay, resulting in a more reliable unit. The actuator electrically isolates components contained within the environmentally sealed enclosure to eliminate the possibility of electrical energy being passed through these components resulting in safer operation.
