Description
SN-2549 Professional Product Description
The SN-2549 is a high-precision ratcheting crimping tool, engineered as an upgraded 2-in-1 integrated model combining the crimping capabilities of SN-01BM and SN-28B jaw sets. It is the industry-standard compact crimper for ultra-fine to small-gauge open-barrel terminals, delivering factory-grade, consistent crimps for electronic wiring, custom harness assembly, and precision prototyping, with exceptional durability, ergonomic handling, and wide terminal compatibility.
Key Features
2-in-1 Integrated Precision Jaw Design
Merging the crimping functions of SN-01BM and SN-28B models, this tool eliminates the need for multiple crimpers. The EDM-machined jaw ensures ultra-tight tolerance and burr-free crimping, preventing damage to delicate terminals and wire cores even for AWG 28 ultra-fine wiresIWISS TOOLS.
Reliable Ratcheting System with Force Adjustment
The full-cycle ratchet mechanism guarantees complete crimping before automatic release, delivering uniform, repeatable crimps every time. The built-in adjustable tension knob allows fine-tuning of crimping force for different terminal materials, while the quick-release lever enables emergency correction of mis-crimps and prevents jammingIWISS TOOLS. The optimized leverage structure reduces hand fatigue by 50% during long-term continuous operation.
Dual-Crimp One-Step Operation
The dedicated dual crimp cavities crimp the wire conductor and insulation strain relief simultaneously in a single squeeze, greatly improving work efficiency. This design enhances the pull-out resistance and electrical stability of the connection, meeting professional wiring harness manufacturing standards.
Industrial-Grade Durability & Ergonomic Handling
The hardened alloy steel jaw with anti-corrosion surface treatment ensures long service life even under heavy use. The ergonomic non-slip handle fits comfortably in the hand, supporting stable one-handed operation in tight spaces, and maintains a secure grip even in wet or oily working conditionsIWISS TOOLS.
Ultra-Wide Terminal Compatibility
Fully compatible with mainstream open-barrel terminals with pitch from 2.0mm to 4.8mm, including Dupont 2.54, JST (PH2.0/XH2.54/SM), Molex (5556/5557/5558/5559/Micro-Fit/Mini-Fit Jr.), KF2510, CH3.96, VH3.96, Faston 110/187/250, as well as ATX, EPS, PCIE, SATA pins for PC building and power supply modificationIWISS TOOLS.
Typical Applications
Electronic prototyping, Arduino/3D printer/robotics wiring projects
Custom Dupont jumper wire manufacturing and PCB circuit wiring
PC building, power supply modification, and consumer electronics repair
Automotive wiring, small home appliance repair, and industrial control wiring
Precision electronic engineering and professional wire harness assembly production
