Product Display
High speed, high pulse, high precision,
resistance to high and low
temperatures, and high stability
Compact structure: The overall layout is reasonable,
saving installation space
Unique design: It adopts a hollow
structure and can be directly slewed onto a rotating shaft
without occupying additional space
Quality Control
Hollow encoders are widely used in the field of industrial automation, such as position control of machine tools and robots. In the power industry, it is used for monitoring the rotational speed and position of generators and steam turbines; It can also be used in elevators, textile machinery, etc., to achieve precise positioning and speed regulation, and improve the performance and degree of automation of the equipment.

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
