Products Description
The PCM-S-0801 JAE to Molex multi-branch wire harness is designed to provide organized low-current electrical connections between a centralized controller and multiple monitoring, sensor or control modules.

The P1 side features a JAE 12-pin black housing with 2.2mm pitch, while the opposite side is divided into four Molex 2-pin black connectors with 3.0mm pitch, identified as P2, P3, P4 and P5.
This multi-branch architecture allows eight defined circuits from the main connector to be routed to four separate two-pin interfaces, making the harness suitable for energy storage monitoring, BMS-related control connections, industrial controllers and electronic equipment internal wiring.
The assembly uses 22AWG UL1452 black wire with a 1.76mm outer diameter. Black PET braided sleeving protects and organizes the main cable section, while heat-shrink tubing, branch identification and nylon cable ties support controlled cable routing.
Each finished harness undergoes 100% open, short and miswire testing before shipment.
Connector configuration, branch length, pin assignment, wire specification, protective sleeving and identification can be customized according to equipment requirements.
Key Features
JAE 12-Pin to Four Molex 2-Pin Design
One JAE 12-pin main interface distributes defined circuits to four individual Molex 2-pin branches for organized multi-module equipment connections.
22AWG UL1452 Control Wiring
Constructed with 22AWG UL1452 black wire, providing a compact wiring solution for low-current signal, monitoring and control circuits.
PET Braided Harness Protection
Black PET braided sleeving and heat-shrink tubing help organize multiple conductors and provide additional mechanical protection along the main harness section.
100% Electrical Testing
Finished assemblies undergo open, short and miswire testing, helping verify circuit continuity and correct pin-to-pin routing before shipment.

Application Scenarios

BMS Monitoring & Control Modules
The four 2-pin branches can provide individual low-current interfaces between a central controller and multiple battery monitoring, sensing or auxiliary control modules.
1.2MWh Large-Scale Energy Storage System
PCM-S-0801 supports low-current monitoring, signal and control connections in 1.2MWh large-scale energy storage systems. Its JAE 12-pin to four Molex 2-pin design connects the main control PCB with BMS monitoring, sensor or control modules, providing organized multi-module wiring without carrying high-current battery power.
