This pre-crimped finished wire-to-board assembly is built with complete original JST ACH series matching components, all parameters cross-verified from JST official catalog and datasheet:
Receptacle Housing PN: ACHFR-03V-H, 3-circuit single-row female crimp socket, 1.20mm center pitch, gray PA66 plastic, no built-in lock buckle
Dedicated Crimp Terminal: ACHF series tin-plated / gold-plated phosphor bronze crimp contact, exclusive for AWG28~32 ultra-fine stranded wire
Mating SMT PCB Header: ACH series vertical surface mount male wafer for PCB reflow soldering connection
The connector adopts unique top-entry vertical mating + horizontal side wire outlet structure: the male header inserts vertically from the top of the housing, while wires extend horizontally parallel to the PCB surface, greatly saving vertical internal space of ultra-thin devices, perfectly solving layout limitations of slim wearables and mini battery modules. The gray PA66 nylon housing features high heat resistance and anti-aging performance, compatible with SMT suction nozzle for automated PCB mounting production.
Two-point elastic crimp terminals maintain ultra-low initial contact resistance ≤10mΩ, stable power and signal transmission without voltage drop under long-term slight vibration. Matched ultra-thin multi-color electronic wires with insulation outer diameter 0.38~0.63mm, color coding simplifies fast circuit identification during assembly.
Every finished harness passes strict full inspection before shipment, including continuity test, terminal pull retention force test, 500V AC high voltage withstand test and thermal cycling aging test. We supply single-end finished cables and cross-type dual-connector conversion harness OEM mass customization solutions for wearable electronics, lithium battery, LED lighting and portable medical equipment manufacturers.

Advantages
Ultra-compact low-profile unique layout: 1.2mm fine pitch + only 1.4mm mated height, vertical plug-in horizontal wire outlet design, drastically save vertical internal space of ultra-thin miniaturized equipment.
Side horizontal wire outlet structural innovation: Wires run parallel to PCB surface, avoid vertical wire bending dead angles, ideal for narrow hinge and flat module internal wiring.
Stable 2A high current capacity in tiny package: Even mini 3Pin 1.2mm pitch connector supports 2A continuous power transmission, balance miniaturization and power supply demand for lithium battery modules.
High elasticity dual-point crimp terminals: Phosphor bronze base with tin/gold plating, excellent oxidation resistance, maintain stable low contact resistance after repeated vibration and temperature cycling.
SMT automated production compatible housing: Reserved suction nozzle area on the plastic shell, support full-automatic pick-and-place PCB mounting, improve factory assembly efficiency.
Flexible full OEM customization support: Arbitrary adjustable cable length, wire thickness and wire color sequence according to customer equipment schematics; small prototype sample orders available for product development verification.
