Cable crimper Knipex 97 53 04 SB

The Knipex 97 53 04 SB cable crimper is a compact hand tool designed for precise crimping of end sleeves (ferrules) according to DIN 46228 parts 1 and 4. It features a narrow handle profile, improved ergonomics and a low weight of 0.405 kg, providing comfortable operation. The tool is factory-calibrated and made from oil-hardened chrome vanadium electric steel for reliable durability.

Advantages

This crimper self-adjusts to the required size of the end sleeve and uses a self-releasing integral lock for consistent, repetitive high-quality crimps. A toggle lever ensures optimum transmission of force and reduces manual effort by approximately 20%. The tool produces square compression for ideal contact surfaces and supports square compression for end sleeves up to 16 mm². It is supplied in a practical colour scheme of black, blue and red and offers fatigue-reduced operation thanks to its handy shape and low weight.

Suitable for

• Crimping single end sleeves (ferrules) to DIN 46228-1 and -4
• Crimping twin end sleeves up to 2 x 6 mm² or 2 x AWG 8
• Applications where reproducible, high-quality electrical connections are required
• Professional and DIY electrical and network installation tasks

How to use

Select the appropriate end sleeve (ferrule) for the conductor, place the ferrule onto the stripped conductor and position it in the crimping die. Squeeze the handles evenly until the integral lock completes the crimp and the tool self-releases. For twin ferrules, ensure correct placement of both conductors in the sleeve before crimping. The tool is factory-calibrated; if calibration is required after extended use, follow the manufacturer's service instructions.

Usage recommendations

Use the tool within the specified crimping range (up to 16 mm² for square compression and up to 2 x 6 mm² for twin ferrules). Store in a dry place and keep the crimping dies clean. Do not use the tool for cutting or on materials outside its intended application to maintain calibration and safety.
