May 28, 2015 - BEI Kimco Magnetics announced LAS13-54-001Z Voice Coil Actuator (VCA) that features an integral built-in position sensor and moving magnet design with resolution and force attributes that can accommodate many applications.
The actuator measures only 5.4" in length with a thin 0.75" diameter over the main body and a 1.3" diameter over the lead wire exit end.
The 0.5" stroke device delivers a peak force of 6.0 lbs. and 20 microns (0.00079") of resolution while weighing only 0.373 lbs.
The tapered styling and size work well for hand tools and other delicate instrumentation, as well as for remotely controlled circuit breakers and industrial automation applications.
The VCA includes all the inherent advantages of moving magnet technology, which features no moving wires and excellent heat dissipation, while providing moderate speed with controllable, gentle stop points. The integrated position feedback sensor eliminates the need for OEMs to add any mechanical parts, simplifying customer inventory, production and installation. And 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 a resolution of 20 microns, this actuator meets accuracy requirements for many applications at a price that is very economical" says Jim McNamara, BEI Kimco Senior Applications Engineer. "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."
