Product Display

The small incremental encoder, with its compact size, can be easily adapted to narrow Spaces
Its incremental design reflects position changes through pulse counting, which is simple and reliable

The small incremental encoder has high-speed response performance and can accurately track dynamic displacement
It has strong anti-interference ability and can work stably in complex environments
Application Cases
The industries and projects involved in small incremental encoders include ports, lifting, shipping, mining, water conservancy, steel and metallurgy, petrochemicals, stone, energy, food processing, aerospace, automobiles, papermaking and printing, injection molding, textiles, stages, glass, packaging, military industry, elevators, machine tools, etc.
Service
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
4. Regarding the warranty of the encoder
