Product Description

The SANTUS ST-202B Crimping Tool is manufactured from premium S50C carbon steel, which undergoes a specialized black oxide treatment to prevent rust and extend tool life. The precision-ground jaws feature multiple nesting stations, allowing you to work with a wide variety of wire gauges from ultra-fine signal wires (28 AWG) to heavy-duty power lines (10 AWG). The tool's "pliers-style" movement provides a tactile feel, allowing the operator to sense the exact moment the crimp is seated. Its lightweight, compact profile makes it ideal for field repairs and intricate bench-top electronics assembly.

Key Features

Multi-Station Jaws: Dedicated slots for different terminal sizes ensure an accurate "M-shaped" crimp.
Integrated Wire Stripper: Features sharp, precision-sized stripping notches that remove insulation without nicking the copper core.
Built-in Wire Cutter: Located at the base of the jaws for quick, clean cuts of copper and aluminum wires.
Ergonomic PVC Grips: High-friction handles provide a secure grip even in oily or humid environments, reducing hand fatigue.
High-Strength Construction: Hardened steel blades maintain their sharpness and alignment through thousands of cycles.

Technical Details

Crimping Logic: Dual-fold crimping for conductor and insulation support.
Weight: ~200g.
Hardness: HRC 45±3.

Prototyping and Engineering Tips from Robogears

The "Two-Step" Crimp: For open-barrel terminals (like JST or Molex), place the terminal in the tool first and give it a very light squeeze to hold it in place. Then, insert the stripped wire and complete the crimp. This prevents the terminal from falling out or being misaligned.
Avoid Over-Crimping: While you want a tight connection, squeezing too hard can "over-crush" the copper strands, making the joint brittle. A perfect crimp should look like an "M" shape where the terminal wings are folded back into the wire.
Stripping Accuracy: Always use the notch that matches your wire gauge. If you use a notch that is too small, you will cut off a few strands of copper, which reduces the current-carrying capacity of your wire and creates a weak point.
Maintenance: Periodically apply a single drop of light machine oil to the central pivot screw. This keeps the action smooth and prevents the buildup of friction that can skew the jaw alignment over time.

1 x SANTUS ST-202B Precision Multi-Purpose Crimping Tool

Disclaimer

This tool is designed for copper and aluminum wires only. Do not use it to cut or crimp hardened steel wires or bolts, as this will chip the precision-ground jaws. Always wear eye protection when cutting wire to prevent injury from flying debris.
