BEI Kimco introduced a new moving magnet voice coil actuator with a flexure design that ensures high alignment accuracy by preventing unwanted shaft rotation. The new VCA provides long life and is ideally suited where extreme precision is required, such as in medical equipment, laboratory instrumentation, clean rooms, low-outgassing, and aerospace applications.

Key Features

• Incorporates a shaft with flexures at both ends of travel that support the moving magnet field assembly
• Characteristics attributed to the flexure design are the elimination of friction and side-loads at non-vertical angles, unwanted particulate accumulation caused from bearing/bushing shedding, and its inherent ability to return the magnet to mid-stroke when re-energized
• Delivers a peak force of 11.9 N and a continuous stall force of 0.7 N
• Package measures just 36.00 mm x 30.00 mm and weighs 0.22 lb
•  Accuracy is limited only by the user’s encoder for feedback
