Product Display

Large-aperture hollow structure: There is a large through hole in the center, which is convenient for shaft parts to pass through. It can be directly installed on the rotating shaft, saving installation space and making the equipment structure more compact. For example, in some mechanical equipment where encoders need to be installed on large transmission shafts, this structure can well meet the installation requirements.
High-precision measurement: By adopting advanced photoelectric or magnetoelectric detection technology, it can precisely measure the rotation Angle and position with high resolution, and achieve precise control and monitoring of moving parts. It is often used in automated production lines and precision processing equipment with extremely high precision requirements.

High reliability: It usually has good anti-interference ability and stability, and can work stably for a long time in harsh industrial environments, such as dust-proof, water-proof, anti-vibration and anti-electromagnetic interference properties, and can adapt to different working environments such as high temperature, humidity and dust.
High rotational speed adaptability: It can adapt to high rotational speeds and accurately measure the position and Angle of high-speed rotating components in real time. It can play a good measurement role in some high-speed rotating equipment such as motors and centrifuges.

Quality Control
The quality of encoders is directly related to the stability and reliability of industrial automation systems. We have established a full-process quality control system, strictly screening suppliers from raw material procurement to ensure that the performance of core components meets the standards. During the production process, high-precision equipment and standardized techniques are adopted, combined with online detection technology for real-time monitoring. During the finished product stage, rigorous tests such as high and low temperatures, electromagnetic compatibility, and life aging are conducted to eliminate potential performance hazards. Each encoder passes through multiple quality inspection checkpoints, laying a reliable foundation for intelligent manufacturing with outstanding quality and providing customers with long-lasting and stable usage guarantees.
Application Cases
Large-aperture hollow encoders are widely used in automated production lines, robots, CNC machine tools, aerospace, medical devices, elevators, wind power generation and other fields, helping various industries achieve precise control and efficient operation.

1. Precautions for Using Encoders
A place where the ambient temperature must not exceed the storage temperature; A place where the relative humidity must not exceed the storage
humidity; It cannot be in places with sharp temperature changes and fogging. Places close to corrosive gases and flammable gases; Stay away from
places with a lot of dust, salt and metal powder. Stay away from places where water, oil and medicine are used; Excessive vibration and shock can be
transmitted to the main body
2. Precautions for Installing Encoders
Electrical components must not be subjected to overvoltage or other phenomena. Please conduct static electricity assessment of the setting
environment, etc. Do not allow the motor power line to approach the encoder. The FG wire of the motor and the FG wire of the mechanical device
must be reliably grounded. Since the shielded wire is not connected to the encoder body, the shielded wire must be effectively connected to the
ground at the user end
3. Precautions on Wiring
When used at the specified power supply voltage, please pay attention to the decrease in power supply voltage amplitude caused by the long wiring.
Please do not use the encoder line and other power lines in the same pipe or bundle them in parallel. Please use twisted-pair wires for the signal line
and power line of the encoder. Please do not apply excessive force to the wire harness of the encoder, as there is a risk of wire breakage
