In a Coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of the magnet eliminating the heavy steel core. This design results in smoother operation and faster response time. jxs 01/20/09 ir/jxs BOX DIMENSIONS: 2.50" W. X 1.38" H. X 3.38" L. BOX WEIGHT: .25 LBS.
