BEI Kimco Magnetics' Voice Coil Actuator Solves Challenging Application Requirements for High Temperature Capabilities

BEI Kimco Magnetics, a company of Custom Sensors & Technologies (CST), Inc., recently met the challenging voice coil actuator requirements for a high temperature spectrometer application. The device is used to identify materials in a given sample based on its spectral lines and operates under severe conditions.

Key to the customer's product design specification was a voice coil actuator that would deliver consistent and reliable performance while operating in a harsh environment under extreme temperatures. In this application, the voice coil actuator is used to move a mirror at high frequency, causing the laser beam to dither. The actuator needed to perform at an ambient temperature of 400º F.

To meet these challenges, BEI Kimco developed a voice coil actuator within the Model LA13-12-000A package. The new design included special Samarium Cobalt (SmCo) magnets and reinforced magnet wire insulation that could withstand high ambient temperatures up to 400º F, a continuous stall force of 0.49 Lb. and a total stroke of 0.25 inches.

"In this example, after going though different product interactions, we were able to meet some very demanding customer requirements." says Jim McNamara, BEI Kimco's Applications Engineer/Project manager for voice coil actuators. "Our customers expect the best designs possible, and we do our best to surpass their expectations. This demonstrates how BEI Kimco really specializes in meeting unique customer needs."

Pricing for the "high temperature" VCA LA13-12 Voice Coil Actuator is from the $100's in production quantities with delivery in 6-8 weeks.
