IWISS IWS-2412M Mini Open Barrel Crimping Pliers AWG 24-12 JST Molex Terminals

🔧 IWISS IWS-2412M Mini Open Barrel Crimping Pliers | AuscomTech

The IWISS IWS-2412M is a compact precision hand crimping tool designed for attaching open-barrel electrical terminals to wires in electronics, electrical wiring harnesses and connector assemblies.

Designed for AWG 24–12 wire sizes, this tool features a double-hinge mechanism and precision crimping jaws to provide controlled pressure for secure electrical and mechanical connections.

Suitable for compatible JST, Molex, Tyco, JAM and other U-barrel terminals, it is ideal for electronics repairs, robotics, automotive wiring, DIY electrical projects and custom cable assemblies where larger wire sizes or terminals are required.

⭐ Key Features

• AWG 24–12 Crimping Range – Designed for open-barrel terminal applications using approximately 0.20–3.31 mm² conductors, subject to terminal compatibility.
• Double-Hinge Mechanism – Provides controlled jaw movement and improved mechanical leverage for precision crimping.
• Precision Crimping Jaws – Designed to fold terminal wings around the wire conductor and insulation for secure connections when used with suitable contacts.
• Multi-Brand Terminal Compatibility – Suitable for selected connector contacts commonly used in electronic and electrical wiring 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 Electrical Tool – Useful for custom wire harness construction, connector repairs and terminal replacement.

⚠️ Important Notes

• Model Supplied: This listing is for the IWS-2412M, specified for AWG 24–12 wire sizes.
• Terminal Compatibility: JST, Molex, Tyco and JAM manufacture multiple contact styles. Compatibility depends on the individual terminal dimensions, barrel geometry and wire size. Not all terminals from these brands will fit.
• Open-Barrel Terminals Only: Intended for compatible uninsulated U-barrel contacts, not standard insulated red, blue or yellow electrical crimp terminals.
• Wire Size Selection: Check conductor size, terminal specifications and required crimp dimensions before use.
• Crimp Quality: Test crimps are recommended to confirm correct conductor compression and insulation support before assembling connectors.
• Manual Crimping Tool: Not a dedicated wire stripper or automatic ratcheting crimper.
• Smaller Terminals: For fine AWG 28–20 open-barrel contacts, the IWISS IWS-2820M model may be more suitable.
• Terminals and Connectors: Sold separately unless otherwise specified.
