cable harness
Product Description
cable harness

1. Product Overview

This product consists of two complementary multi-core wire harness configurations, both terminated with white JST-compatible female connector housings on each end, presented as a batch production set:
 
The first configuration (upper group in the image) uses twisted/bundled multi-core wire in four colors — red, black, green, and teal/cyan — with the conductors loosely bundled along the full cable run. The twisted layout reduces electromagnetic interference between conductors and is commonly used for signal lines and mixed power-signal applications.
 
The second configuration (lower group in the image) uses a flat parallel arrangement of four conductors — red, black, yellow, and green — laid side by side in a ribbon-like format. This flat layout keeps all conductors in a fixed spatial relationship, simplifying identification and routing in confined spaces.
 
Both configurations use IEC/industry-standard color coding to differentiate conductor functions, enabling faster assembly and reduced wiring errors. The white JST-compatible connector housings on both ends allow direct plug-in connection to mating male headers on PCBs, modules, or sub-assemblies without soldering.
 
Multiple identical harnesses are visible in each group, confirming consistent batch production. Both configurations are suited to low-voltage signal and power distribution in consumer electronics, industrial equipment, and automation hardware.
 
Key features:
 
Two configurations: twisted bundle (4-core) and flat parallel (4-core)
IEC-style color-coded conductors for easy identification (red / black / green / teal; red / black / yellow / green)
White JST-compatible female connectors on both ends
Automated crimping for consistent contact seating
100% continuity tested before shipment
RoHS compliant materials
OEM/ODM accepted; custom length, pin count, and color combinations available

2. Technical Specifications

Parameter Specification / Status
Connector Type JST-compatible female housing, white, both ends

Configuration B Flat parallel 4-core: Red / Black / Yellow / Green
Connector Orientation Same direction, A-A (both ends identical)
Termination Automated crimp, both ends
Certification RoHS compliant

3. Application Scenarios

Development Boards & Prototyping Both harness configurations are directly compatible with JST PH/XH/ZH headers widely used on Arduino, ESP32, STM32, and Raspberry Pi peripheral boards. The color-coded conductors allow power (red/black) and signal (green/yellow/teal) lines to be instantly identified during prototyping and debugging without a multimeter.
 
3D Printers & Desktop CNC Machines Twisted 4-core bundles are used to connect thermistor sensors, heated bed connectors, and stepper motor sub-connectors to main control boards in desktop 3D printers, where the twisted construction reduces noise pickup in proximity to stepper motor drivers. Flat parallel harnesses connect display ribbon-style leads and endstop switches.
 
Battery Management Systems 4-pin JST harnesses are a standard choice for connecting BMS balance boards to cell tap wiring in small lithium battery packs (e.g. 4S configurations), where each color corresponds to a specific cell tap for unambiguous identification during assembly and servicing.
 
Consumer Electronics Internal Assembly Used as internal power and signal interconnects in smart home devices, wireless speakers, handheld game controllers, and portable instruments where the compact JST connector allows tool-free disconnection of sub-assemblies during repair and the color coding ensures correct re-assembly.
 
Industrial Sensors & Automation Modules Connects 4-wire sensors (VCC, GND, signal, optional shield) and multi-channel I/O modules to control boards in compact automation hardware, PLC expansion modules, and sensor arrays inside industrial enclosures.
 
Medical & Portable Diagnostic Devices Used as internal signal harnesses in handheld diagnostic instruments and monitoring accessories where the compact connector pitch, color traceability, and RoHS compliance meet product assembly and regulatory requirements.
