10 and 11-bit Industrial Absolute Encoders
The R30 is a 10-bit, single-turn, digital, rotary absolute position
encoder intended for industrial applications requiring up to 1024 uniquely
identifiable positions per revolution. The SR30 provides up to 11-bits
and uses a patented, cost
saving technology that relaxes the precise alignment tolerances of conventional
absolute encoders by an order of magnitude without sacrificing accuracy. The
result is a fully functional, yet lower cost alternative. The SR30
updates the outputs at 1KHz and the SR31 updates at 3KHz.
