Non-Insulated Terminal Crimping Tool (220mm)

The 6PK-301N is a ratcheting crimper for Y- and O-type non-insulated terminals, supporting conductors from 1.25-8 mm². Its dies are made from AISI 4140 alloy steel, and it includes ratchet release and crimp-force adjustment.

It is suitable for non-insulated terminal crimping in control wiring, automotive circuits, appliance repair, building electrical work, and general DIY. The ratchet provides a more consistent crimp profile and repeatability than a basic multipurpose plier.

The dies are designed for Y- and O-type non-insulated terminals so force is applied at the correct location on the terminal barrel. Place the terminal in the cavity matching its cross section; do not use insulated sleeves or other terminal types interchangeably.

The alloy-steel dies withstand repeated crimping loads and retain their shape. Do not crimp steel wire, screws, or materials outside the specified range, as this can chip or deform the dies.

Select the die cavity according to the conductor cross section and terminal marking and confirm that all copper strands are fully inserted into the barrel. A conductor and terminal mismatch can cause pullout, severed strands, or a jammed die.

The handles must complete the full ratchet stroke before release to ensure the required crimping force. If a terminal is positioned incorrectly, use the release mechanism; do not pry the tool open.

If a crimp is too loose or too tight, adjust the force slightly according to the instructions. After every adjustment, make a test crimp with the same terminal specification and perform a pull check before production use.

Disconnect power and verify that the conductor is de-energized before crimping. The covered handles are not VDE insulation. After crimping, inspect for stray strands, cracks, terminal misalignment, or excessive exposed copper.

Remove copper debris and dust from the dies, lightly lubricate the pivot, and keep the ratchet clean. Stop using the tool if release is abnormal, a die is chipped, or a handle is loose.

The 6PK-301N is specifically for Y/O non-insulated terminals. Insulated terminals, ferrules, coaxial connectors, and network plugs each require different dies; select a dedicated tool for the terminal construction.
