Product Description

Restriction of Hazardous Substances

US Digital offers a wide variety of standard hub / disk assemblies (optical encoder disks attached to an aluminum hub) to aid with mounting on a shaft. Encoder disks may also be ordered as a stand alone item (see the Disks page). These rotary encoder disks are made from mylar polyester film. This material allows for a wide temperature range of -70°C to +100°C and are virtually unbreakable.

HUBDISK-1 consists of a precision machined aluminum hub fastened to a 1" diameter optical encoder disk (DISK-1). A set screw is used to attach the hub to a shaft. The codewheel is available with bore sizes ranging from 2 mm to 10 mm. All hub bores are held to a very tight tolerance of -0.0000 to +0.0005 inches.

The disk on the assembly comes attached with the emulsion side up / right reading (see drawings provided).

The index option is not available on the following resolutions: 110, 120, 540 and 1016 CPR.

The following resolutions are only available with the index option: 32, 720, 900 and 1250 CPR.

Mechanical alignment drawings for optical encoder rotary disks and optical encoder modules are available (see the EM1 and HEDS pages).

Product Notes
  • US Digital warrants its products against defects in materials and workmanship for two years. See complete warranty for details.
  • Please note that rotary hub / disk assemblies and optical encoder modules are sold separately.
