ST49 Fast charging data cable 60W Type-C to Type-C /30W Type-C to Lightning

ST49 Long Strain Relief Bend-Resistant Braided Fast Charging Data Cable

Product Overview
The ST49 series is a professional-grade bend-resistant data cable featuring an extended strain relief design. By reinforcing the connector junction structure, it significantly enhances cable durability in frequent bending scenarios. This series offers four independent connector models: USB to Lightning/Micro/Type-C, Type-C to Type-C, and Type-C to Lightning. Each model is available as a separate SKU, allowing users to precisely select based on their device requirements.

Key Selling Points

1. 30mm Extended Strain Relief Bend-Resistant Design

• A specially extended 30mm flexible TPE strain relief at the rear of the connector effectively disperses bending stress, shifting the bending point from the connector to the more durable cable body area.

• Passed 5,000 ±90° bend fatigue tests, with a bending lifespan 300% longer than traditional designs.

• The strain relief features a tapered streamlined design to avoid stress concentration points.

2. Three-Layer Composite Dynamic Buffer Structure

• Inner Layer: Highly elastic TPE dynamic buffer layer that absorbs bending deformation energy in real time.

• Middle Layer: 96-strand high-density diagonal braiding provides dual protection against longitudinal tension and lateral torsion.

• Outer Layer: Food-grade TPE coating offers a skin-friendly feel and self-repairing properties.

3. Intelligent Power Management System

• Automatically recognizes device charging protocols and intelligently matches mainstream fast-charging solutions such as PD3.0, QC4+, and AFC.

• Supports stable output of up to 60W high power, with a temperature rise in the strain relief area ≤8°C during full-load operation.

4. Military-Grade Durability Standards

• Connectors are made from CNC-machined aluminum alloy in one piece, with internal reinforcement frames extending to the start of the strain relief.

• The junction between the strain relief and cable body uses a five-layer injection molding process, with peel strength ≥50N.

• The entire series passes 1.5-meter drop tests and high/low temperature cycling tests from -40°C to 85°C.

Use Cases

• Continuous bending and vibration environments such as in-car charging and navigation.

• Frequent plugging/unplugging of mobile devices in industrial settings.

• Scenarios requiring high reliability, such as medical equipment charging.

• Public charging stations with long-term plug/unplug usage.

Technical Features

• Strain Relief Bend Life: ≥10,000 cycles (test standard: ±90° per cycle)

• Operating Temperature Range: -40°C to 85°C

• Tensile Strength: ≥120N (including strain relief section)

• Connector Plug/Unplug Lifespan: ≥15,000 cycles

• Oil and Corrosion Resistance Rating: IP54

Usage and Maintenance

1. Allow the strain relief to bend naturally; avoid manual reverse 180° folding.

2. Regularly clean the folds of the strain relief to prevent dust buildup affecting heat dissipation.

3. For in-car use, it is recommended to use fixing clips to reduce the impact of continuous vibration.

4. If used in high-temperature environments for extended periods, check the elasticity of the strain relief every six months.
