Domestic pull-wire encodersThere is no uniform fixed standard for the price.
In actual industrial applications, the price range varies significantly based on factors such as measurement range, accuracy, structural design, and communication methods.
Therefore, a more reasonable approach to determining the price of domestic draw-wire encoders is to understand“What factors determine prices?”rather than simply comparing numbers.
Short-travel draw-wire encoder
Medium-to-Long Stroke Cable-Type Encoder
Long-Stroke Draw-Wire Encoder
Generally speaking, the larger the measurement range, the higher the structural and material costs, and the higher the price accordingly.
This is one of the most critical factors affecting price:
Drawing wire + Incremental encoder
The structure is relatively simple.
Lower cost
Suitable for speed or relative displacement measurement
Drawing wire + Absolute encoder
Supports power-off position memory
Higher technical complexity
The price is significantly higher than that of incremental models.
General industrial precision
High precision / High repeatability
The higher the precision requirements, the greater the demands on the machining consistency of the encoder and cable pull mechanism, naturally leading to increased costs.
Different output methods have a significant impact on pricing:
Analog signals (e.g., 4–20 mA)
SSI, RS485
CANopen, Profibus, Profinet
Parallel I/O
Fieldbus protocols typically cost more than basic signal outputs.
Ingress Protection Rating (IP)
Vibration-resistant and shock-resistant design
Construction machinery or heavy-duty application structures
These factors will directly impact the final price of domestically produced draw-wire encoders.
Without specifying particular brands or models, the prices of domestically produced draw-wire encoders typically fall within the following ranges:
Basic Pull-Wire Encoder: Suitable for General Industrial Measurement
Engineering-grade draw-wire encoder: Suitable for construction machinery and port equipment
High-Precision / Bus-Type Cable Encoder: Ideal for Automation and Critical Position Measurement
In actual projects, the final price is typically determined after technical specifications are confirmed.
From an engineering application perspective:
Domestic pull-wire encoders
More cost-effective for engineering projects
Short lead time
Customizable and flexible
Imported Draw-Wire Encoder
The unit price is relatively high.
Long lead time
Customization costs are high.
This is also one of the key reasons why domestically produced draw-wire encoders have been widely adopted in construction machinery, port operations, and automation projects.
When selecting models in practice, it is recommended to consider the following points, rather than focusing solely on price:
Does it meet the measurement accuracy requirements?
Is it compatible with the control system protocol?
Is it suitable for the on-site conditions?
Whether capable of providing long-term supply and technical support
Price should serve the stability of the project, not be the sole deciding factor.
The core advantage of domestically produced draw-wire encoders lies in achieving more reasonable overall cost control while meeting industrial application requirements.
By clearly defining application requirements and technical specifications, you can obtain a more tailored pricing proposal.
