BEI Kimco, a brand of Sensata Technologies, has introduced a moving magnet Voice Coil Actuator with a flexure design. The VCA also provides long life and is ideally suited where precision is required, such as in medical equipment, laboratory instrumentation, clean rooms, low-outgassing and aerospace applications. The Housed Linear Actuator Model LAH13-11-000A incorporates a shaft with flexures at both ends of travel that support the moving magnet field assembly. In addition to preventing shaft rotation inaccuracies, other 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. The actuator delivers a peak force of 11.9 N and a continuous stall force of 0.7 N in a package that measures 36.00 mm x 30.00 mm and weighs 0.22 lb. About BEI Kimco BEI Kimco specializes in the design and manufacture of high performance rotary and linear motion components, including Brushless DC Motors and Voice Coil Actuators. These products are designed for applications where performance, precision, and reliability are critical.
