Product ReleaseBEI Kimco Voice Coil Actuator Offers Improved Consistency and Precision in Valve Control and Beam Steering Applications
BEI Kimco Magnetics, a company of Custom Sensors & Technologies (CST), has introduced a new compact sized, high force, cylindrical Voice Coil Actuator in response to market demand for improved consistency and precision in valve control and beam steering applications. Typical uses include analytical/test and measurement equipment for the pharmaceutical, R&D, laboratories, and medical industries. Designed with high force sensitivity in a lightweight housing, the new actuator provides extremely fast control of valve opening and closing, thereby increasing throughput for OEMs looking to improve production and reduce product time to market. Used in conjunction with a high performance motion controller or other device, the actuator is capable of providing precise positioning, velocity, and acceleration in applications where exacting precision is critical. The new actuator is available in small sizes from 1-inch OD to 1-1/2-inch OD for installation into products with tight space constraints. Features include stroke lengths ranging from 0 to 1.27 mm, force versus position curve characteristic, continuous force of 1 to 5 N, cog and hysteresis-free operation, and tight tolerances. The unit can be ordered in a variety of materials, allowing the OEM to select an actuator that is compatible with the type of sample being tested at the final point of use. "Chemical compatibility is an important aspect for many of these types of applications," explains Miguel Hermosillo, Application Sales Engineer for BEI Kimco. "To address this, BEI Kimco provides a variety of material choices for the customer to select from, thereby ensuring compatibility between the chemical being tested and the actuator itself." In addition to material choices, several other product configurations are available. Customers can select the lead, stroke length, voltage, shaft, and linear or rotary design that meets their specific application requirement. "This versatility allows us to meet the variety of anticipated customer requirements for unique uses," adds Hermosillo. The new actuator is competitively priced from $45.00 in production quantities with lead times of stock to eight weeks.
