This wire harness features a black and grey dual-tone PET expandable braided sleeving over the cable body, giving each unit a premium, textured appearance while providing mechanical abrasion protection along the full cable run. Each harness terminates with a white 4-pin connector housing with four visibly seated copper/tin-plated crimp contacts, secured by a black rubber or moulded heat-shrink strain relief boot with a flared trumpet-shaped entry that distributes bending stress away from the crimp zone.
The dual-tone black and grey braid pattern is consistent with high-quality PET expandable sleeving used in consumer electronics, PC modding, and automotive interior assemblies where both durability and aesthetics matter. The flared strain relief boot provides a smooth cable entry profile that prevents sharp-angle flexing at the connector body, extending service life in applications subject to repeated handling, vibration, or cable movement.
Three identical harnesses are shown at slightly different lengths or angles, demonstrating consistent batch production quality: uniform braid coverage, identical boot moulding profile, and aligned connector orientation across all units. The batch production code "21827" is printed on the cable jacket for traceability.

2. Application Scenarios
PC Modding & Desktop Computer Builds The dual-tone black and grey braided sleeving is a signature aesthetic choice in the PC modding and custom build community, where enthusiasts replace stock cables with sleeved harnesses for case window visibility. The 4-pin configuration is compatible with standard fan headers, RGB connectors, and peripheral power leads commonly used inside PC chassis.
Consumer Electronics Internal Assembly Used as internal signal or power interconnects in gaming peripherals, smart speakers, and portable devices where the sleeved finish provides abrasion resistance during assembly and the strain relief boot protects crimp connections from flex fatigue caused by repeated lid opening, hinge movement, or cable routing.
Automotive Interior & Infotainment 4-pin braided harnesses connect sensor modules, ambient lighting controllers, seat memory modules, and infotainment sub-assemblies inside vehicle interiors where the PET braid resists abrasion from body panels and trim edges, and the strain relief boot withstands constant low-level vibration over the vehicle's service life.
Industrial Sensors & Control Modules Used to connect 4-wire sensors (power, ground, signal, shield), encoder modules, and proximity switches to control boards inside production machinery and conveyor systems, where the braided outer layer protects against abrasion from adjacent metal structures during maintenance and operation.
Smart Home & IoT Devices Internal power and signal harnesses in smart home hubs, display panels, and building automation controllers use this construction for a durable, professional internal finish that survives production-line handling and field servicing over the product's service life.
Robotics & Motion Control Applied in robotic joint cable runs and linear actuator assemblies where the PET braid tolerates repeated flexing and the flared strain relief boot prevents crimp fatigue at the connector entry point — a critical failure point in harnesses subject to continuous cyclic motion.
