HAAP1208/HAA with Pull – Navigation System

Cable Wiring Harness Assembly Process Guide. Harness Navigation System, CPG.

It is a process improvement tool for making a cable wiring harness sub assembly. It checks for correct continuity, insertion location, and terminal backout TBO. It guides the operator from where to pick up a crimped cable and where to insert a crimped cable.

Other names are Harness Navigation System, CPG, Point guide and Harness Assembly Aid. 

De-skill Harness Assembly Process

Main advantage of the system is de-skilling the Cable Wiring Harness assembly process. A new person learning time is very short and assembly done is without any errors. It saves time and efforts of reworking after end of line testing.

The complete system is :
1) Test blocks / fixtures with LED indication (I/O LEDs) under each cavity to indicate where to insert. Test block also has a switch which operates on pulling a locked cable.
2) Treys with LEDs on each trey to indicate from where to pick up a cable.
3) HAAP1208 slave unit connected to trey LEDs, I/O LEDs and switch indicating pull.


1) HAAP1208 is a compact unit working on 12VDC, with appropriate connectors.
2) It is programmable using a keyboard or using soft program and USB pendrive.
