Modular Encoder offers 576,000 measuring point resolution.

Press Release Summary:

Measuring .75 x 1.78 x 2.3 in., CP-250-HHC incremental hollow-shaft encoder offers 8 user-selectable resolutions from 5,000-144,000 quadrature cycles per revolution with repeatability of ±1 count. It can be adapted to shafts up to .39 in. and mounted to any available platform. Along with max frequency of 3 MHz and .25 mm non-glass disk to optics distance, product features differential digital line driver output that optimizes noise immunity.

Original Press Release:

Computer Optical Products Introduces Modular Hollow-Shaft Encoder for Resolutions up to 576,000 Measuring Points

Modular Incremental Encoder Size .75 x 1.78 x 2.3 inches.
Mounting 1.34 x 1.34 inches. User-selectable resolution from 5,000 to 576,000 counts per revolution.

Computer Optical Products, Inc. (COPI), an Allied Motion Technologies company, has augmented its modular encoder CP-2XX line with a special, high-resolution option.

The CP-250-HHC is an extremely versatile and rugged incremental encoder with eight user-selectable line counts. The cost effective unit offers a resolutions range from 5,000 up to 144,000 quadrature cycles per revolution (up to 576,000 measuring points) with a repeatability of +/- 1 count.

As a hollow-shaft encoder it can be adapted to shafts up to .39" (10mm) and can be easily mounted to any available platform. With a maximum frequency of 3 MHz the encoder allows a high motor RPM rate as well as a high resolution. The differential digital line driver output guaranties high noise immunity even when used with long cable runs.

The .25 mm (10 mil) non-glass disk to optics distance makes the unit very forgiving for motor run out and thermal shaft growth. Application include motors, actuators, medical devices, scanners, spectrum analyzers, monochromators, XY tables and in general any application where high resolution is required.
