BEI Kimco Magnetics' New Linear Voice Coil Actuator Features

The LA13-13 was designed in response to customer demand for an actuator that could provide continuous operation under highly contaminated conditions and withstand splashes and sprays from water or other fluids without malfunction. It provides a cost-effective solution for initial purchase and prevents expensive actuator replacement costs due to failure from contamination.

To our knowledge, this is a unique product - others are manufactured with metal enclosure and screws making them expensive and heavy, says Miguel Hermosillo, BEI Kimco's Applications Engineer for VCAs. With our rubber bellow design, we can deliver a lighter weight and lower cost package. This product enhances our existing actuator line with additional capabilities and demonstrates our commitment to solving customer problems, he adds.

For sealing, the device incorporates a rubber bellow that attaches to both the actuator coil and the assembly. Its contoured design allows free actuator movement. Operating characteristics include a peak force of 16.7N, a total stroke of 6.36 mm, and an actuator constant of 2.47 N/sqrt(watt). The unit measures 33.5 mm OD by 28.45 mm in length and weighs 117 grams.

For installation, the actuator is mounted on the field assembly side using a hollow fitting that equalizes the actuator pressure. Pricing for the LA13-13 Sealed Voice Coil Actuator is from $200.00 each in small production quantities with delivery in 8-10 weeks.

BEI Kimco Voice Coil Actuators have been used successfully in countless applications from high-end Industrial to Military and Aerospace to Medical applications. The ability to provide high performance solutions tailored to the specific needs of the customer has allowed BEI Kimco to fulfill many challenging requirements.
