Product Details

The JR12 model from Quantum Devices, Inc. provides an advanced feedback solution for applications usually involving pancake resolvers with identical threaded shaft and jam nut mounting. The JR12, standing less than an inch tall and utilizing the stability of a bearing encoder design, can provide substantial performance enhancements in applications traditionally restricted by standard resolvers or modular encoder solutions.

Output options encompass a quadrature with index pulse and three-phase commutation. A flexible element allows for increased tail shaft run out and TIR, which modular encoder designs usually can't tolerate, and the integrated mounting flange obviates the need for costly servo mounting clips.
