Long Working Range Draw-wire Encoders
The maximum measuring stroke of the BRG-9005 rope displacement sensor is 5000mm. It is a high-end brand product launched by us. This product adopts large-diameter multi-strand steel wire rope and independent automatic winding spiral structure, which completely eliminates the wire jamming and breaking failures of imported products. It is mainly suitable for high precision, long life and harsh working environment. It is at the leading level internationally and can completely replace imported products.

Features
Compact Structure and Space Adaptability
- Integrated Design: Combines linear and angular displacement sensing technologies, featuring a compact size (some models have a diameter <50mm), making them suitable for confined spaces (e.g., robotic arm joints, equipment cavities).
- Flexible Installation: Supports horizontal, vertical, or inclined mounting, with some models offering flange or threaded fixation options for complex working conditions.
Ultra-Long Stroke Capability
- Measurement Range: Standard models cover 1mm to 50m, while customized versions can exceed 100m (e.g., for bridge monitoring sensors).
- Multi-Turn Encoder Technology: Utilizes helical springs or constant-force springs for long-distance extension/retraction, preventing wire slack or breakage.
High Precision Performance
- Analog Output: Typical accuracy of 0.05% FS (e.g., ±5mm error for a 10m range), with high-end models reaching 0.01% FS.
- Digital Output:
- Incremental Encoder: Resolution of 0.001mm/pulse (e.g., 5000 PPR models).
- Absolute Encoder: SSI or CANopen interface, with no cumulative error, suitable for power-off position retention.
Vibration and Interference Resistance
- Dynamic Compensation: Built-in spring tension adjustment system minimizes measurement jitter caused by mechanical vibrations.
- Electrical Isolation: Opto/magnetic isolation on signal outputs suppresses electromagnetic interference in industrial environments.
Enhanced Durability
- Wire Rope Material:
- Core: High-tensile stainless steel wire (breaking strength >2000N).
- Coating: Teflon (resistant to acids/alkalis, operable at -60°C to 260°C).
- Lifespan: Standard models exceed 1 million cycles (e.g., IP66-rated products).
Multi-Interface Signal Output
1.Analog Options: 4-20mA (high noise immunity), 0-10V (fast response), potentiometer-type (passive output).
2.Digital Protocols:
- Incremental Encoder: A/B/Z phase pulses with quadrature decoding support.
- Bus-Type: PROFINET, EtherCAT (for Industry 4.0 integration).
