JCS900-2AE 50mm/100mm Digital Readout Linear Scale Encoder with Accessories Features: The reading head of this sensor uses ball bearing positioning and orientation for small friction, high sensitivity and long service life. The sensor uses precision metrology grating as measuring device, high measurement precision. It is practical for refinement of machine tools which have lost precision; using grating digital display machine tool can greatly improve machining accuracy and production efficiency. The sensor has sealed structure, reliable performance, easy installation, and is unmatched by any other digital display system. It can be used for linear digital display of all kinds of small and middle machine tools and other precision measuring, to achieve accurate measurement and positioning.
