Common Applications
The Fm-DZQ is an SN-28B style ratcheting crimper for open-barrel terminals in the 28-18 AWG (0.1-1.0 mm2) range. It handles 2.54 mm Dupont, JST XH and VH, KF2510 and Mini-Fit Jr style pins commonly used in PC PSU extensions, GPU power leads, custom Dupont jumpers and 3D printer wiring. Three crimp profiles in a single jaw form the wire barrel and insulation grip in one squeeze. The ratchet mechanism prevents partial crimps - it will not release the jaws until full crimp force is reached, which is what gives the tool its repeatable pull-out strength compared to plier-style crimpers.
Frequently Asked Questions
Q: Which terminals does the Fm-DZQ crimp?
A: Open-barrel pins in the 28-18 AWG / 0.1-1.0 mm2 range, including Dupont 2.54 mm, JST XH and VH, KF2510 and Molex Mini-Fit Jr.
Q: Why won't the tool release until fully closed?
A: The SN-28B ratchet mechanism is intentional. It blocks the jaws from opening until full crimp force is reached so every crimp meets the same pull-out spec. Use the release lever if you need to abort a crimp.
Q: Does it crimp insulated/closed-barrel ring or spade terminals?
A: No. This is an open-barrel crimper for the PC and electronics terminal styles listed above. Closed-barrel insulated terminals need a different jaw geometry.
Q: Do I need to adjust ratchet tension?
A: It ships pre-calibrated. After extended use the tension can be adjusted via the screw on the ratchet to restore consistent crimps.
Q: What wire stripper pairs with it?
A: A 22-10 AWG stripper like the FormulaMod Fm-XQ covers the upstream cut/strip step, with the Fm-DZQ handling the crimp.
