Compact VCA's long stroke offers versatility

The actuator measures only 13.72cm in length with a 1.91cm diameter over the main body and a 3.3cm diameter over the lead wire exit end. The 1.27cm stroke device delivers a peak force of 2.72kg and 20μm of resolution while weighing only 0.169kg. The tapered styling and size work exceedingly well for medical hand tools and other delicate instrumentation, as well as for remotely controlled circuit breakers and industrial automation applications.

The integrated position feedback sensor eliminates the need for OEMs to add any mechanical parts, simplifying customer inventory, production and installation. Its voice coil technology offers direct-drive, zero backlash and cog free operation for accurate motion as well as high acceleration and absence of commutation. With this latest addition to the line, BEI Kimco's linear actuators with built-in sensors now have strokes of 0.635, 1.27, 2.54 and 3.175cm. Compared to the two closest products in the family, this unit has a longer stroke than two actuators larger in size. With its thinner, longer package design, it fits specific space needs that other actuators cannot.

"With a resolution of 20μm, this actuator meets accuracy requirements for many applications at a price that is very economical" says Jim McNamara, Senior Applications Engineer, BEI Kimco. "High resolution sensors can be very expensive, and we often encounter applications where submicron position accuracy is just not needed. The LAS13-54-001Z offers good performance that is more than ample for many applications."
