IWISS IWS-2820M Mini Open Barrel Crimping Pliers AWG 28-20 JST Molex Terminals

🔧 IWISS IWS-2820M Mini Open Barrel Crimping Pliers | AuscomTech

The IWISS IWS-2820M is a compact precision hand crimping tool designed for attaching small open-barrel electrical terminals to wires in electronics, wiring harnesses and connector assemblies.

Designed for AWG 28–20 wire sizes, this tool features a double-hinge mechanism and precision-machined jaws to provide controlled crimping pressure for reliable electrical and mechanical connections.

Suitable for compatible JST, Molex, Tyco, JAM and other U-barrel terminals, it is ideal for DIY electronics, Arduino and ESP32 wiring projects, robotics, repairs and custom cable assemblies.

⭐ Key Features

• AWG 28–20 Crimping Range – Designed for small open-barrel terminals used with approximately 0.08–0.52 mm² conductors.
• Double-Hinge Mechanism – Provides controlled jaw movement and improved mechanical leverage for precision crimping.
• Precision Crimping Jaws – Designed to fold terminal wings around the conductor and insulation for secure connections when matched to suitable terminals.
• Multi-Brand Terminal Compatibility – Suitable for a range of compatible connector contacts commonly used in electronics and electrical assemblies.
• Compact Hand Tool – Approximately 180 mm long, making it convenient for workbenches, portable toolkits and field repairs.
• Durable Metal Construction – Stainless-steel construction provides strength and corrosion resistance for repeated workshop use.
• Manual Operation – No electrical power, batteries or additional machinery required.
• Versatile Electronics Tool – Useful for custom wire harness construction, terminal replacement and connector repairs.
