Quality Control
The quality of encoders directly impacts the stability and reliability of industrial automation systems. We have established a comprehensive quality control system, rigorously screening suppliers from raw material procurement to ensure that core components meet performance standards. During production, we employ high-precision equipment and standardized processes, coupled with real-time monitoring through online testing technology. At the finished product stage, we undergo rigorous testing for high and low temperatures, electromagnetic compatibility, and lifespan aging to eliminate performance risks. Each encoder undergoes multiple quality inspections, ensuring superior quality and a solid foundation for intelligent manufacturing, ensuring long-term, stable operation for our customers.
Application Cases
The KON113 series products are suitable for industrial servo control, precision machinery, robotics, logistics AGVs, and rail transit auxiliary systems.

| Phillips Torque Screwdriver Metric 1.5mm Across-Flat Hexagon Torque Wrench |
| 3. Installation Procedure | |
| Stator Installation: ① Align the front face (electronics side) of the stator with the A-side of the mounting jig, and align the pin holes with the jig's locating pins. ② Reverse the assembled stator and jig, aligning the stator legs with the mounting platform and the jig's center hole with the mounting axis to position the stator motherboard. Secure the motherboard with five M2.5×8 Phillips-recessed small pan head screws and flat washers, applying a final tightening torque of 5-7 kgf·cm. ③ Slowly remove the jig, taking care not to tilt it. The stator is now installed. [Notes]: 1) Pay attention to the screw head height, especially at the star mark "*." The height of the screw head protruding from the PCB must be less than 2.3mm. 2) To prevent the screws from loosening, pre-apply threadlocker to the threaded holes or use screws with pre-applied threadlocker. |
| Rotor Installation: ① Align the back of the rotor (not the encoder) with the B side of the mounting jig. Be mindful of the impact of the magnets during attraction, and align the rotor shaft hole as closely as possible with the jig shaft hole. ② Reverse the assembled rotor and jig, aligning the rotor shaft hole with the mounting shaft. Slowly push the jig downward, keeping the jig flat and parallel to the mounting platform. Stop when the jig legs are aligned with the mounting platform. Be careful not to push the rotor too far. Use two M3×3 hexagon socket head set screws with a torque of 7 kgf/cm to tighten the rotor to the shaft. (Be mindful of the effect of the rotor magnet's attraction on the screws and tools to avoid contact and damage to the encoder.) ③ Remove the jig. Rotor installation is complete. After rotor installation, rotate the rotor one full revolution to check for interference, paying particular attention to the screws on the bottom of the encoder. Remove the encoder protective film and clean the encoder surface with a cotton swab or dust-free cloth. After installation, proceed to the next step of testing. |
4. Precautions
This encoder has a split-body design. The encoder shaft (including the code disc) is separate from the main unit.
The encoder shaft and motor shaft must be exposed to air during installation. Please assemble in a clean, dust-free environment.
Before installation, degrease and clean the motor shaft to prevent oil and dirt from interfering with the encoder shaft's tightness and contaminating the code disc.
Be careful not to touch the code disc directly with your hands or other hard objects. Fingerprints, oil, dust, and other debris can cause signal abnormalities, and hard objects can damage the code disc.
After installation, inspect the surface of the reflective code disc for cleanliness.
If contamination is detected, gently wipe it with a dust-free cloth or other material dipped in alcohol.
Please note that excessive force or use of hard materials may damage the code disc.
