2Axis 3 Axis Digital Read Out DRO


Product origin :Jilin, China

Delivery time :5 working days

Supply capacity :5000 pcs per week

2Axis 3 Axis Digital Read Out DRO is a display instrument that integrates the application and operation of the lathe, milling, grinding, boring machine, measuring machine, professional control machine.
A digital readout (DRO) is a display unit which reads the signals generated by the linear encoder (or less frequently by rotary encoders) installed to several machine axes(2axis and 3 axis ,etc optional), used to display the position, speed and angle of workpiece (milling and the like) or tool (lathes and grinders)

ROUNDSS as China the 2nd largest encoder manufacturer, supply a perfect design digital readout products you can select.



● High accuracy resolution,

● Nonlinear error compensation: multi-point nonlinear error compensation. 

● Upper and lower spacing alarm function: Set the machinery coordinate spacing alarm.,

● RS-232: Data exchange interface, 

● Backlash compensation: It can be connected to the encoder to compensate the backlash of the gear, rack and screw 

and I/O

● Interface: can be set according to customer's requirements

Our digital display meters are one of our highly demanded products and are used in various industrial applications. These 

are developed using advanced electronic technology and they have personality designs. Other salient features of the 

product include:

● Speed of count response is very effective and it has many powerful functions

● Solid, durable and attractive cover which is not easily scratch able

● Strong anti-interference of power

● Durable panel, which is simple and conversion

A tachometer (revolution-counter, Tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a 

shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a 

calibrated analogue dial, but digital displays are increasingly common.

Company Building

Roundss was founded in 2006. It is a professional rotary encoder manufacturer with 11000 sq factory. The headquarter is in 

Changchun, which is the photoelectric industry base of China. Roundss has 4 sales branches, 30 full-time sales staff and 18 

agents in China. We will provide the quality optical encoders and good service to customers in fast response.

Factory Show

Roundss has 11000 sq meter factory including machining workshop and dust free assembly workshop. The automatic 

assembly line was developed by Roundss, which is the first in encoder industry. We have 8 production lines: universal 

incremental encoders; absolute encoders; manual pulse generator; draw wire sensor; magnetic ring encoder; gear tooth

encoder; servo motor encoder; flexible couplings. We could provide 3000pcs encoders for one week. For every encoder

before leaving factory, it must pass two times of singal inspections.


All encoders passed CE certificate. Some encoders like MPG, handwheel are RoHs compliant. Roudss spends 6% of annual 

income on science and technology activities and R&D. Now we have got more than 40 national patents.

International Exhibitions

Each year, ROUNDSS attends around 10 international exhibitions, such as IMTS, JIMTOF, EMO, SIMTOS, SPS IPC Drives 

and so on. The rotary encoders are welcomed by customers around the world. Now encoder products have been exported 

to more than 50 countries.


Roundss has 12 agents around the world. Haas, Beijing-Fanuc and Bosch group are all our partners. Wide selection of 

encoder products is available. The incremental encoder and MPG are our star products. Roundss also supply the customized

encoder service. We welcome partners to visit our company to talk about cooperation details. 

Group Activity

ROUNDSS has about 150 employees. We pay attention to the growth of each partner, respect employees, care for employees,

and improve employees. Roundss group will devoted ourselves in encoder industry and supply the best rotary encoders to you!
