Optical Linear Scale 0.005mm for DRO Lathe Milling Machine TTL KA300 120-520mm

Upgrade your milling, turning, or grinding setup with the Optical Linear Scale KA-300. This high-precision DRO scale covers available travel from 70 mm to 1020 mm and delivers a 0.005 mm (5 µm) resolution with TTL output, helping you achieve tighter tolerances and smoother cutter paths on mills, lathes, grinders, and CNC machines. Built for reliability, the KA-300 uses a 45-degree oblique grating for improved signal transmission, reduced wear, and longer scale life, even in demanding shop conditions. The scale features IP54 protection, a 3 m cable, and a DB9 interface for easy integration with most DRO systems. With an operating temperature range of 0-50°C and a rugged Mainland China build, the KA-300 is the smart choice for precision feedback in every machine shop.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
