SINO Brand KA-300 Series Optical Linear Glass Scale — KA300-120-970/0.005 mm

The SINO KA-300 is a high-precision optical linear glass scale used in machine tools like lathes, milling machines, and grinders to provide accurate position feedback to a Digital Readout (DRO) or CNC system.

The KA-300 series is available in two primary resolutions: 5µm (0.005 mm) for standard precision applications and 1µm (0.001 mm) for high-precision requirements.

The SINO KA-300 series offers a wide range of measuring lengths, from 70mm up to 1020mm, to fit various machine sizes.

The KA-300 has an IP55 protection rating, which means it is protected against dust ingress and low-pressure water jets from any direction, making it suitable for typical workshop environments.

It provides a TTL / EIA-422A (RS-422) output signal, which is a standard interface compatible with most DRO systems and CNC controllers.

Yes, its high accuracy, robust construction, and standard signal output make it an excellent choice for providing position feedback on a wide range of CNC machinery.

The scale requires a standard 5V DC power supply.

We offer a 1-year manufacturer's warranty on all SINO KA-300 linear scales purchased from us.

Yes, we provide a GST invoice for all B2B purchases, allowing you to claim input tax credit.

Yes, we deliver the SINO KA-300 linear scales across India to all major industrial and metro areas.

This model is ideal for users with small machines requiring standard precision, such as benchtop lathes or mini-mills, where the travel distance is short.

This is for users with small machines who need higher accuracy for fine detail work, such as jewelry making or small-part grinding.

This is suited for medium to large machines like full-size milling machines or lathes where a long travel distance and standard industrial precision are required.

This high-precision, long-travel scale is for large machinery involved in high-accuracy tasks like aerospace component manufacturing or large-format grinding.

This is the longest scale in the series with standard resolution, perfect for large lathes and milling machines that require maximum travel measurement with reliable accuracy.

This top-of-the-line model offers the maximum length and highest precision, designed for the most demanding applications on large, high-precision machinery.

The 1µm resolution model is five times more precise than the 5µm model. Choose 1µm for high-precision tasks like grinding or jig boring, while 5µm is sufficient for general milling and turning operations.

Measure the maximum travel distance of the machine axis you want to fit the scale to. Choose a scale with a measuring length equal to or slightly greater than this distance. The total physical length of the scale will be longer than its measuring length.

For high-precision grinding, the 1µm resolution version is strongly recommended as it provides finer feedback, enabling you to hold tighter tolerances.
