SN-2549 Ratchet Crimping Pliers — a professional tool for creating reliable electrical connections without soldering. Designed for crimping open non-insulated contacts of Dupont, JST, Molex and many other connectors, which are widely used in electronics, robotics, automotive electrical, automation systems and DIY projects.
The Dupont Ratchet Crimping Tool or SN-2549 Crimping Pliers is an indispensable assistant for working with various types of connectors and terminals. It is designed for crimping non-insulated open drum terminals AWG28-18, such as JST, Dupont, Molex, and is a combination of the SN-01BM and SN-28B connector crimpers.
Anyone who has ever tried to crimp a small contact with ordinary pliers knows how difficult it is to get a high-quality and neat connection. Uneven force often leads to poor contact, wire loss or terminal damage. That is why professional craftsmen use SN-2549, which provides a stable result almost from the first attempt.
The tool is equipped with a ratchet mechanism (ratchet) that automatically controls the crimping process. Until the contact is crimped with the required force, the pliers will not open. This allows you to get factory quality connections even without extensive experience.
Advantages of the SN-2549 model:
- 🔧 Professional crimping of contacts without soldering
- ⚡ Ratchet mechanism ensures the same quality of each crimp
- 🎯 Precise matrix for small electronics contacts
- 🛠 Simultaneous crimping of conductor and insulation
- 🔄 Adjustment of crimping force for different types of contacts
- 🖐 Ergonomic handles for comfortable work
- 💪 Durable construction made of hardened tool steel
How a ratchet works mechanism?
After installing the contact in the matrix and starting to squeeze the handles, the mechanism gradually increases the crimping force. The tool holds the contact until the end of the cycle, which eliminates the possibility of incomplete crimping.
Thanks to this, the contact tightly covers the conductor and insulation, providing reliable mechanical fastening and high-quality electrical contact. This is the principle used in the production of cable assemblies and wire harnesses.
Additional information about the Dupont ratchet crimper or SN-2549 crimping pliers includes the following functional features:
-
Jaw pressure adjustment: The tool has the ability to adjust the jaw pressure for optimal crimping of different materials. To do this, unscrew the screws and turn them in the "+" direction to compress the jaws and in the "-" direction to for relaxation.
-
Handle design: The handle is specially designed with human factors in mind to ensure comfort and energy saving during crimping. The lightweight and compact design of the handle provides a perfect crimping effect, making the process more efficient and comfortable.
