GENERAL INFORMATION
The Z50-020 IDC Termination Hand Tool is used to ensure the complete and secure assembly of IDC
connectors. The tool uses a ratchet mechanism and press plate to assemble the connector onto the ribbon
cable. The tool is also supplied with a desk clamp, for secure fastening during operation.
The connector is fully assembled once the tool is free to open fully to its original position, i.e. when the
ratchet releases. The ratchet releases once the handles have been compressed to the fully closed position.
ASSEMBLY PROCEDURE
1. Decide whether you will clamp the tool to the desk or use the tool in hand. If clamping the tool
to a desk, make sure the tool is securely fastened before use.
2. Select a suitable ribbon cable for the connector.
Harwin recommends:
Wire Type = UL2678
Wire Pitch = 0.635mm
Wire Thickness = 30AWG
3. Feed the cable into the back of the connector, ensuring it is the correct width and cut to the
desired length.
ToolClamp
Hook the clamp onto the
undercarriage of the tool.
Tighten the clamp onto the
designated desk.

4. Make certain that the termination hand tool is in the fully open position, and that the jaws are
free from dirt and debris.
5. Feed the cable through the slot and securely place the connector within the locating feature
(Female) or flush against the stop washer situated to the right of the tool (Male). See figures 1,
2 & 3.
6. Once the connector is in the correct position and secure, slowly compress the handle until the connector
is fully shut and the ratchet within the tool has released.
7. If assembling a second connector to the cable, it is not recommended to feed the wire through the slot.
Instead, assemble the cable into the connector from above. This way, you will be able to terminate the
connector, and still be able to remove the finished assembly from the tool. Please see figures 4 & 5
below as examples.

Tool Maintenance
1. Keep the tool clean and free from dirt and foreign matter. Ensure that all pins and clips are in place
before use, and that signs of wear are not visible. If the pivots are worn, the tool must be replaced, or
integrity of assembly will be compromised.
2. Oil at all pivots and bearings using light cycle oil.
3. At regular intervals, check the assembly tool jaws for wear or damage, and inspect sample connector
assemblies for form and function.
