Product Description
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 and is virtually unbreakable.
HUBDISK-2 consists of a precision machined aluminum hub fastened to a 2" diameter optical encoder disk (DISK-2). One or two set screws (depending on the hub's ID) are used to fasten the hub to a shaft. The codewheel is available with bore sizes ranging from 2 mm to 1 inch. All hub bores are held to a very tight tolerance of -0.0000 to +0.0005 inches.
Only the No Index, EM1 Compatible option (NE) is available with the 64 CPR option. Other resolutions are available with or without an index track.
Mechanical alignment drawings for optical encoder rotary disks and optical encoder modules are available (see the EM1 and HEDS pages).
