Application

High Accuracy Linear Scale and Digital Read out System (DRO) Series

DRO Linear scale when used in conjunction with our Counter is designed for manual machine tools or other equipment having linear movements, for example cut off saws.

Alternatively the scale output can be used for automatic positioning control of machine tools or similar equipment via CNC or PLC units.
The scales may also be fitted to co-ordinate measurement or other measurement equipment used for high accuracy inspection & measurement

Brief introduction to product classification:

• The optical grating sensor linear scales manufactured by us are divided into two types, open and closed type.
• The open type is high precision and is designated JCT, the scale output wave is sine wave, they are mainly used in digital measurement equipment and offer a highest resolution of 0.1um.
• The closed type is mainly -used in conjunction with our DRO counters on machine tools and similar equipment, these scales are designated JCX and have a scale output is square wave. (TTL or RS422)
• A complete range of accessories is provided to facilitate installation.
