9. Precautions
9.1Regarding vibration
The vibration added to the rotary encoder often causes pulse errors, so you should pay attention to the installation location. The more pulses per revolution, the narrower the slot interval of the grating, and the more susceptible it is to vibration. When rotating at low speed or stopping, the vibration added to the shaft or body causes the grating to shake, which may cause pulse errors.

Quality Control
The quality of encoders is directly related to the stability and reliability of industrial automation systems. We have built a full-process quality control system, strictly screening suppliers from raw material procurement to ensure that the performance of core components meets standards; in the production process, we use high-precision equipment and standardized processes, and cooperate with online detection technology for real-time monitoring; in the finished product stage, we conduct rigorous tests such as high and low temperature, electromagnetic compatibility, and life aging to eliminate performance risks. Each encoder has passed multiple quality inspection levels, and its excellent quality has laid a solid foundation for intelligent manufacturing, providing customers with long-term and stable use guarantees.
Application Cases
The S18 series encoders are compact, ultra-thin, high-resolution, and highly anti-interference. They are widely used in industrial automation (servo motors, robot joints, CNC machine tools, elevators, wind turbines), electronic manufacturing (money counters, copiers, printers), medical equipment (CT scanners, surgical robots), and automobiles (steering, braking, suspension systems), providing precise position and speed feedback.
Service
I. Precautions for using the encoder
Places where the ambient temperature does not exceed the storage temperature; places where the relative humidity does not exceed the storage humidity; places where the temperature changes sharply and fogging occurs; places close to corrosive gases and flammable gases; places away from dust, salt, and metal powder; places where water, oil, and medicines are used; places where excessive vibration and impact will be transmitted to the body
II. Precautions for installing the encoder
Electrical components must not be subjected to overvoltage and other phenomena. Please conduct an electrostatic assessment of the setting environment, etc. Do not bring the motor power line close to the encoder; the FG line of the motor and the FG of the mechanical device must be reliably grounded; due to shielding The wire is not connected to the encoder body. Please make sure that the shielded wire is effectively connected to the ground at the user end.
III. Precautions on wiring
When used under the specified power supply voltage, please pay attention to the power supply voltage amplitude drop caused by the long wiring; please do not use the encoder wire and other power wires in the same pipe or bundle them in parallel; please use twisted pair wires for the signal wire and power wire of the encoder wire; please do not apply excessive force to the encoder harness, there will be a risk of disconnection
