IWISS iCrimp SN-28B Dupont Crimping Tool for 2.54/2.5/3.96mm Pitch | JST XH/VH & Dupont Connectors | AWG 18-28

Overview

The IWISS iCrimp SN-28B is a compact ratcheting crimp tool designed for open barrel terminals found in common connector families such as JST XH VH and Dupont style 2.54 mm pins. It supports a broad wire range from AWG 18 to 28 (0.1–1.0 mm²), making it a flexible option for both power and signal wiring in hobbyist and DIY projects as well as small-scale prototyping environments.

What makes crimps repeatable

Ratcheting action paired with precision dies and an integral lock helps deliver repeatable, solderless crimps across multiple cycles. The self releasing mechanism minimizes hesitation during the crimp and the 20° angled head improves reach in tight enclosures, reducing strain during longer sessions.

Key capabilities

• Purpose: crimp non insulated open barrel OEM style terminals
• Wire range: 0.1–1.0 mm², AWG 18–28
• Pitch compatibility: 2.5 mm, 2.54 mm and 3.96 mm terminals including JST VH XH NH and Dupont 2.54 mm
• Applications: ideal for wires on rechargeable battery packs balancers BECs 3D printers and RC servos
• Durability: designed for repetitive, high‑quality crimps with a reliable integral lock

Practical use cases

• Wiring battery packs and balance leads for RC models or DIY power projects
• Attaching JST XH VH and Dupont style terminals to multi‑pin harnesses
• Creating clean, reliable crimps in compact enclosures such as printers and robotics controllers

Note that the SN-28B covers a range of pitch variants and wire gauges commonly listed in its spec sheet. This makes it a versatile addition to a workshop where various JST and Dupont style connectors are in use.
