Voice Coil Actuator Outfits Linear Servo Mechanisms

Targeting applications that include fast valves in respiration equipment, auto-focus capabilities in optical systems, and active damping in instrumentation, the LA50-65-001A voice-coil actuator measures 5" and delivers a linear stroke of 1" (i.e. ±0.5" from mid-stroke). The component provides a peak force of 225 lbs. and accelerations up to 72g. Sporting a cylindrical configuration, it can operate in temperatures up to 155°C. According to the company, the actuator's strong force and fast dynamic response provides the performance necessary for high-end servo applications where both speed and accuracy are critical.
