The iCrimp SN-28B is a precision crimping tool designed for creating secure connections with Dupont, JST XH, and JST VH connectors. It accommodates a wide range of connector pitches, including 3.96mm, 2.54mm, and 2.5mm, making it suitable for various wiring projects. The tool handles wire gauges from AWG 18 to AWG 28, offering flexibility for both thicker power wires and thinner signal wires. Its construction features a robust steel frame and ergonomic handles, ensuring consistent crimping pressure without excessive hand fatigue during repetitive tasks.

The crimping mechanism is engineered with a ratchet action that releases only after full compression, guaranteeing that each crimp is completed to the correct depth. This helps maintain electrical conductivity and mechanical strength across all connections. The die set is precisely machined to match the profiles of Dupont terminals as well as JST XH and VH housings, reducing the risk of bent pins or loose fits.

Users can expect reliable performance for prototyping, repairs, and small-scale production work. Durability is addressed through the use of hardened steel components and a powder-coated finish that resists rust and wear. The tool’s alignment guides are designed to keep terminals centered during crimping, minimizing waste.

The handles include soft grips that provide a secure hold even in slightly damp conditions. Routine maintenance involves occasional cleaning and light lubrication of the pivot points to sustain smooth operation. This model is particularly well-suited for electronics enthusiasts, technicians, and hobbyists who work with wire harnesses or connector assemblies.

Its ability to switch between different pitch sizes without needing additional accessories adds convenience. The compact size allows it to fit in standard toolkits or storage drawers. At a price point that balances affordability with professional-grade features, the iCrimp SN-28B offers a practical solution for achieving consistent, repeatable crimps across multiple connector families.
