Voice Coil Actuator BEI Kimco (Vista, CA) has introduced a family of linear unhoused Voice Coil Actuators (VCAs) with aperture sizes of 15 mm, 20 mm, and 24.9 mm. The through-hole design allows an OEM assembly to pass directly through the middle of the actuator, resulting in reduced weight, fewer parts, and a more compact product overall. Auto focusing equipment to support lab equipment that use lasers, lights, wires, lenses, or tubes filled with gas or fluid can be inserted directly through the VCA aperture to save space in tight designs. With capabilities for low out-gassing, these VCAs are also well suited for optical instruments where it is important to prevent film from building up on lens or glass.
Additional space-savings beyond the through-hole design is achieved with actuator sizes that measure as small as 1.5" (38.1 mm) in diameter and 1.56" (39.6 mm) in length (at midstroke). Other product performance features include total strokes ranging from 0.25" to 0.45" and peak forces of 14 lbs. to 45.2 lbs. respectively.
