Product Details

The JR12 model from Quantum Devices, Inc. serves as an upgraded feedback solution in instances usually employing pancake resolvers with matching threaded shaft and jam nut mounting. Thanks to its sub-one-inch height and the resilience of a bearing encoder design, the JR12 can deliver notable performance upgrades in scenarios typically constrained by traditional resolvers or modular encoder solutions.

Output options of the JR12 consist of a quadrature with an index pulse and three-phase commutation. A flexible member accommodates more tail shaft run out and TIR than is generally allowed by modular encoder designs. Plus, the built-in mounting flange obviates the need for expensive servo mounting clips.
