Q: Encoder Selection Guidance
A: Deep thinking in progress...
First, I need to recall the basic principle and role of encoder. In the field of modern industrial automation and intelligent manufacturing, encoder, as a key sensor, can convert mechanical motion into electrical signals, accurately measure and feedback parameters such as angle, position, and speed, to realize accurate and stable operation of your equipment.
Next, I need to confirm the mechanical key parameters:
Body size: φ10~φ60mm
Mounting type: bushing, screw, servo, flange
Shaft type: protruding shaft, blind hole shaft
Shaft diameter: φ3, φ6, φ8, φ10, φ12mm, etc. Special customization is available.
Lifespan expectancy: up to 2,000,000,000 times
Ingress Protection: up to IP67
Then the electrical parameters:
Basic type: incremental type, absolute type
Number of turns: single turn, multi-turn (30~16384 turns)
Pulse number: any number of pulses within 4096ppr can be set
Resolution: 10 bit, 12 bit, 14 bit
Voltage supply: 3.3V, 5V, 12V, 24V, etc.
Output signal: incremental pulse, SSI, SPI, USB, CANopen, RS485, 0~5V, 0~10V, 4~20mA
There are also additional functions such as zero setting, connectors and cost/performance trade-offs.
Finally, there are application scenarios to consider. For example, is the encoder used for high-level CNC and robots, high-performance medical equipment or agricultural machinery? Different application scenarios have different focuses.
According to the actual scenarios, I have organized and summarized some typical customer demand cases, and make the following recommendations for you:
Case 1: Limited space for internal installation of equipment
Recommendations: EI18A and EI22A are our two popular small-size encoders, the outer diameter is only 18mm and 22mm, only the size of a thumbnail, does this meet your needs? If you need something smaller, we can also provide customized products in 12mm or even 10mm.
Case 2: Blind shaft products
Recommendations: We have a variety of blind hole shaft products, they all come with elastic flange mounting piece, such as general φ6mm products EI36B-F1, EI40B and EBS40A-F1, if you want other shaft diameter or imperial-unit shaft products you can choose EI40NB. 
Case 3: The shaft is required to be able to carry some loads
Recommendations: Heavy-duty encoders of the 58 series with a shaft load capable of withstanding radial forces of up to 80N and axial forces of up to 40N. Depending on your output signal requirements, we can offer you products with different outputs such as push-pull (EID58A), SSI (EAMD58A) and bus type (EBMD58A).
Case 4: Absolute multi-turn measurement requirement, 30~4096 turns
Recommendations: Our absolute multi-turn encoder EAM50A / EBM50A series products are characterized by reliable lap information output and no loss of information after power failure. It has a single-turn resolution of up to 14 bit (16384), a multi-turn number of up to 12 bit (4096 turns), an update speed of 10 μs, and is highly resistant to magnetic interference. You can choose between SSI and bus-type output signals depending on the equipment used. Meanwhile, we also have the economical EAM30A / EBM30A series for 30 and 60 turns, which can also meet the digital and bus output requirements. 
Case 5: Manual adjustment of the zero position
Recommendations: EAM30A / EBM30A series absolute encoders are available. In order to make it easier for users to install and adjust on-site, this series of encoder has an external zero setting interface, which can set the zero position at any position, so that there is no need to find the zero point on-site when installing. Push-pull, SSI, CANOPEN and Modbus outputs are available.
The above cases are product recommendations for some specific needs. If you want to choose a regular encoder product, we recommend you to use the powerful filtering function of SIBO official website for selection.
How to use: Please visit SIBO official website http://www.qcdsupch.cn/Encoders.html, select the parameters you want, and then you can filter out the suitable encoder for you.
