Linear Voice Coil Actuator - BEI Kimco Magnetics Div

July 20, 2011
BEI Kimco Magnetics has introduced the LA13-13 Linear Voice Coil Actuator featuring an IP64 fully sealed package impervious to water splashes  and other fluids.  This new light-weight actuator provides reliable, long lasting performance in highly contaminated environments and is ideally suited for industrial, semiconductor and medical applications. 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.
