transmissiveMylar

2 in. outside diameter Product Description US Digital offers a wide variety of standard HubDisk assemblies (optical encoder disk attached to an aluminum hub) to aid mounting onto a shaft. Encoder disks may also be ordered as stand-alone items. The rotary encoder disks are made from 0.007 in. thick Mylar polyester film, and the material allows for a -40C to 100C temperature range. The disk on the HubDisk assembly comes attached with the emulsion side up when the disk text is right-reading. HUBDISK-2 consists of a precision machined aluminum hub fastened to a 2 in. diameter optical encoder disk (DISK-2). One or two set screws (depending on the hub's bore size) are used to fasten the hub to a shaft. The HubDisk assembly is available with bore sizes ranging from 2mm to 1 in. All HubDisk assembly bores are held to a very tight tolerance defined by US Digital Technical Bulletin Shaft and Bore Tolerances TB1001.
