Last time, we introduced absolute encoders for you. You shoud have got better understanding of the characteristics and advantages of absolute encoders. We also have received readers’ active inquiries: What output signals are available for the absolute encoder ?

1. Absolute encoder -- serial output

Serial output of absolute encoders has become the mainstream of communication transmission in all walks of life because of its advantages of fewer channels, and a variety of interfaces and protocols have been developed, which includes SSI, SPI, 232 for point-to-point communication, and 422, 485, CAN for multipoint communication in networking.

Take CAN as an example, we usually say that CAN includes interfaces at the physical layer and protocols at the application layer. On the interfaces of the physical layer, CAN generally contains four contacts: power supply, ground, CAN_H and CAN_L. Differential signals are formed between CAN_H and CAN_L for signal transmission. Its communication transmission distance can be up to 10km, and the maximum communication rate can be up to 1Mbps.

At the application level, CAN has develped various protocols, such as CANopen, J1939, DeviceNet, SDS, etc. corresponding to different application occasions. In addition, there are a variety of non-standard custom protocols.

These various interfaces and protocols often make unfamiliar friends dizzy. Don't worry, SIBO’s absolute encoders can realize the above types of serial output, supporting the selection and customization of various protocols. As long as you tell us your needs, we can make a suitable solution for you.

2. SIBO’s absolute encoders

SIBO has a wide variety of absolute encoders, including single-turn EBS36A, EBS40A, EBS40B, etc., and multi-turn EAM30A, EBM30A, EBMD58A, EBM50A. All have their own characteristics and can adapt to a variety of different applications. EBM30A absolute multi-turn encoder has to be mentioned among them. It is a miniaturized absolute multi-turn encoder developed by SIBO through innovative structure and algorithm design. It solves the urgent demand of small size, low price and high reliability for multi-turn encoder in the industries, with the following advantages:

◆Compact size

Patented structure and algorithm design can realize up to 80 absolute multi-turn measurements in a space of 30×35×21mm.

◆Solid housing case

Adopt metal housing case, surface anti-rust treatment, solid and reliable, and unique anti-skid installation design on the bottom.

◆Extremely high resolution and measurement accuracy

Single-turn resolution can reach 14bit (16384), repetition accuracy ±1Lsb, linearity ±0.3%.

◆Diversified output types

It can ouput CAN bus signal, MODBUS RTU bus signal, SSI signal and other serial signals. In addition, it also keeps the analog output signal (R30M) for traditional potentiometer users.

◆Humanized setting mode

With external zero setting interface, you can set zero at any position, and it is unneceaary to find zero during installation, which is convenient for on-site installation and debugging. Analog output products can also set the zero position and full scale position.

◆High security and reliability

With reverse connection protection function, it has good electromagnetic shielding performance, which makes it work well in various vibration environments and electromagnetic complex environments.

3. Various applications of EBM30A

EBM30A multi-turn absolute encoder , as a new member of SIBO encoder series, has been widely used in machine tools, industrial robots, instruments, intelligent storage, sewing equipment, medical equipment and other industries. If you have the need for multi-turn absolute position measurement, don't miss it! SIBO, there is always one type of encoder that can meet your needs.
