Pince à dénuder Knipex 12 40 200

The Knipex 12 40 200 cable stripper is a precision tool for removing insulation from single, multiple and fine-stranded conductors with plastic or rubber insulation. It automatically adapts to the cable cross-section to avoid damage to the conductor and includes a wire cutter for copper and aluminium conductors. The tool is 200 mm long, weighs 0.202 kg and has a fiberglass-reinforced plastic body and oil-hardened special tool-steel blade for long service life.

Advantages

The stripper adapts automatically to varying cable diameters and offers an adjustable cutting depth to suit different insulation materials. It features a smoothly operating mechanism, easily replaceable stripping blades and clamping jaws, a built-in cutter for copper and aluminium wires (multiple stranded up to 10 mm², single stranded up to 6 mm²), and a lightweight construction for comfortable handling. A model variant is available for thin ribbon cables up to 10.0 mm width in a single pass.

Suitable for

• Electricians performing installation and maintenance work

How to use

Select the appropriate cable position and place the conductor into the stripper so the blades contact the insulation.

Use the integrated cutter to cut copper or aluminium conductors within the specified cross-section limits. Replace stripping blades or clamping jaws when wear affects performance.

Recommendations

Use the cutting-depth adjustment to prevent conductor damage, inspect blades regularly for wear, and select the ribbon-cable model for single-pass stripping of cables up to 10.0 mm width. Follow standard safety practices and wear protective equipment when working with live installations.
