Product Details

The JR12 model by Quantum Devices, Inc. furnishes an enhanced feedback solution in instances generally involving pancake resolvers with the same threaded shaft and jam nut mounting. With an overall height of less than an inch and the stability of a bearing encoder design, the JR12 model can significantly improve performance in contexts usually bound by standard resolvers or modular encoder setups.

Output possibilities comprise a quadrature with index pulse and three-phase commutation. A flexible member allows for a greater degree of tail shaft run out and TIR than modular encoder designs usually accommodate, plus the built-in mounting flange eliminates the need for high-cost servo mounting clips.
