Small Actuators Offer Through-Hole Design

Description

In order to simplify assemblies and save space, the number of OEMs looking for a way to insert their equipment directly through a Voice Coil Actuator (VCA) is on the rise for medical, scientific, and analytical laboratory instruments.  In response to this increasing demand, BEI Kimco has introduced a family of linear unhoused VCAs with aperture sizes of 15mm, 20mm, 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.  

Available in three standard models, the new military and medical grade actuators offer the ruggedized quality and durability critical to many types of industrial applications. 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.
