Product Overview
The YN31118 Intelligent Cable-Specific Projector is a precision dimensional measurement instrument designed specifically for the wire and cable industry. Combining optical projection with digital image processing technology and featuring a precision stage, the device enables accurate, non-contact measurement of critical dimensions—such as insulation thickness, sheath thickness, and outer diameter. It integrates intelligent data processing capabilities to automatically calculate statistical metrics (minimum, maximum, and average values) and supports the printing of measurement results, providing an accurate and efficient solution for dimensional quality control in cable manufacturing.

Why Is Precision Cable Dimensional Measurement Crucial?
Insulation and sheath thicknesses are core structural parameters that directly impact a cable's electrical safety and service life:

Insufficient insulation thickness: Can reduce dielectric strength, potentially leading to insulation breakdown during operation;

Excessive insulation thickness: Not only wastes material costs but also compromises cable flexibility and heat dissipation performance;

Uneven thickness: Core eccentricity (excessive deviation between the thinnest and thickest points of the insulation layer) causes significant variations in electrical performance across different directions, with the thinnest point becoming a weak spot prone to breakdown;

Outer diameter deviation: Can affect installation and laying, as well as compatibility with connectors and terminals.

Standards such as GB/T 2951.11 and IEC 60811-201 clearly specify the measurement methods and acceptance criteria for insulation and sheath thicknesses. Accurate and reliable dimensional measurement is not only a mandatory requirement for final product inspection but also a vital basis for process control and quality traceability during production.

Key Features and Technical Advantages
Advanced Optical Projection Measurement System
High-Definition Optical System: Utilizes high-quality optical lenses and an illumination system to clearly project the magnified profile of the cable cross-section onto the viewing screen. The image features sharp edges and high contrast, facilitating precise positioning of measurement boundaries;

Precision Stage: Equipped with a high-precision X-Y traversing stage (refer to technical specifications for measurement range and resolution), enabling accurate positioning and movement to perform multi-point measurements at various locations on the sample;

Non-Contact Measurement: Eliminates sample deformation and human error associated with contact-based measurement methods; particularly suitable for the precise measurement of soft, elastic materials (such as rubber, thermoplastic elastomers, etc.).

Intelligent Measurement and Automated Calculation
Automatic Calculation of Minimum Point: After performing multi-point measurements on the insulation and sheath layers, the system automatically calculates and marks the minimum thickness value—a critical indicator for compliance assessment—thereby avoiding omissions or errors that might arise from manual identification and calculation;

Comprehensive Statistical Analysis: Automatically calculates statistical data such as maximum, minimum, and average values ​​for the same sample, allowing for a thorough assessment of dimensional uniformity;

Built-in Compliance Assessment: Automatically determines whether measurement results meet pre-set standards (PASS/FAIL), enhancing inspection efficiency.

Convenient Data Output and Management
Built-in Printer: Enables real-time printing of measurement results—including individual point readings, minimum/maximum/average values, and relevant statistical data—facilitating the generation of formal inspection reports and record-keeping;

Data Storage: Capable of storing multiple sets of measurement data to facilitate quality traceability and statistical analysis (optional feature).

Standards-Compliant Measurement Methods
The equipment strictly adheres to the technical requirements for insulation and sheath thickness measurement outlined in GB/T 2951.11-2008 and IEC 60811-201; measurement accuracy and operational procedures fully comply with these standards. Robust and Reliable Structural Design
Features a cast-iron base and precision guide rails, ensuring smooth stage movement and sustained accuracy over long-term use;

The overall structure offers high rigidity and vibration resistance, making it suitable for stable, long-term operation in both factory workshops and laboratory environments;

Compact footprint with overall dimensions of approximately 1000mm × 730mm × 730mm × 1060mm.

Energy-Efficient and Eco-Friendly Electrical Design
Power supply: AC 220V, 50/60Hz

Total power consumption: Only 350W; low operating costs, suitable for continuous, long-duration operation.

Typical Testing Workflow
Specimen preparation: Cut a 20mm–50mm section from the finished cable, ensuring the end face is flat, burr-free, and undeformed (cryogenic sectioning may be used to assist in preparing soft materials);

Specimen mounting: Place the specimen on the stage and use the X-Y translation stage to position the cross-section of interest in the center of the projection field of view;

Focusing and magnification: Adjust the focus to ensure a sharp, clear projected image and select the appropriate magnification level;

Measurement operations:

Insulation thickness measurement: Select at least six measurement points evenly distributed around the circumference of the insulation layer, measure the thickness at each point, and have the system automatically record the values ​​and identify the minimum;

Sheath thickness measurement: Measure the sheath layer thickness using the same method;

Outer diameter measurement: Measure the cable's outer diameter and automatically calculate the maximum, minimum, and average values;

Data evaluation and output: The system automatically determines pass/fail status based on preset standards and generates measurement reports as required. Technical
