RESOLUTION ADJUSTABLE DRO is designed to match multi kinds of linear scale with resolution 0.05µm, 0.1µm, 0.2µm, 0.5µm, 1µm, 2µm, 5µm, 10µm, 20µm or 50µm. The DRO resolution must be set to completely match the linear scale precision. (This kit default is 5um/0.005mm/0.0002" resolution) 9 PIN CONNECTION Readout only allows TTL square wave signal input through 9 pins connector, which completely matches the linear scale encoder . Pin 1 to 4 connects +5V,0V,A,B , and the pin 5-9 are blank. DURABLE KEYBOARD Robust casing, high reliability and durability switch design. Full-closed design ensures its clean and dust resistance, safety increased. Having a good capacity of resisting disturbance,durable keyboard,easy to change LINERA SCALE with 3 METER CABLE Signal cable uses multilayer shielded wire steel and metal shell to provide extra protection . Deafult offer 3 meters (9.84feet long) cable connecting with linear scale. FULL SET ACCESSORIES Full set of installation accessories (L type cover, backplate and screws ) included , each scale equipped with some extra screws to avoid unsccessful installation . WIDELY APPLICATION Widely used for manual machine ,such as milling machine ( for Bridgeport Mill, Knee Mill,Rong Fu 31 mill / drill, Grizzly Mill,etc), drilling machine, grinding machine, lathe, EDM, linear cutting machines etc. DRO Functions : Circumference holes processing Linear holes processing ARC processing Oblique processing Slope processing Chamber processing R function Tool diameter compensation function Digital filter radius diametr, mm/inch function etc. Package Included : 1pc 3Axis DRO Digital Readout 3pc Linear Scale (upon your choice) 1pc English User Manual 3pc Mounting Cover 4pc L type Mounting Plate 1 full set Installation screws Specifciations : Scale Travel (measuring) length : 50/100/150/200...1000MM (come in 50mm increment) Supply Voltage : AC 80V~260V; 50~60Hz,US Plug Power consumption: 15VA Operating temperature: 0~45°C Storage temperature: -30~70°C Signal Input : TTL square wave Resolution : 5µm (0.005mm/0.0002") Overall Length : Travel Length + 140mm Linear Scale Interface: DB9(RS232) Installation On Lathe Mill Machine 3 Axis DRO Digital Readout 5um Display Read Out Mill Lathe 0.0002“ Resolution 3 Axis Digital Readout DRO Kit 150mm+300mm+550mm 2 Axis Digital Readout DRO Kit 300mm+900mm 2 Axis Digital Readout DRO Kit 300mm+1000mm 2 Axis Digital Readout DRO Kit 200mm+950mm Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.3 out of 5 stars 42 4.3 out of 5 stars 84 4.4 out of 5 stars 33 4.5 out of 5 stars 94 4.5 out of 5 stars 94 Price $113.99$113.99 $262.99$262.99 $237.99$237.99 $275.99$275.99 $227.99$227.99 2 Axis Digital Readout DRO Kit no data no data no data ✓ ✓ 3 Axis Digital Readout DRO Kit no data ✓ ✓ no data no data 3 Axis DRO Digital Readout ✓ no data no data no data no data
