BEI Kimco has recently introduced a family of linear unhoused VCAs with aperture sizes of 15mm, 20mm, and 24.9mm. 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.
The new military and medical grade actuator offers the ruggedized quality and durability critical to many types of industrial applications and is available in three standard models. Auto focusing equipment to support medical and other 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 valuable 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” (38.1mm) in diameter and 1.56” (39.6mm) in length (at mid-stroke).
