Digital actuators are actuation devices that receive and respond to discrete digital command signals rather than analogue inputs, encompassing components such as stepper motors, digitally controlled solenoids, and pulse-width-modulation (PWM)-driven drive mechanisms used in flight control, fuel management, and landing gear systems, together with the associated digital interface protocols, embedded control electronics, and position-feedback encoders that enable precise, repeatable positioning within fly-by-wire (FBW) architectures.
How many distinct aircraft programmes each supplier in this area is linked to in our database — a proxy for how widely established a company is across the industry. Bars are relative to the top-ranked supplier.
Whether supply here is concentrated in a few big players or spread across many. Top-5 share is the portion of all programme links held by the five largest suppliers. HHI (Herfindahl–Hirschman Index) runs 0–10,000: under ~1,500 is competitive, over ~2,500 is concentrated.
