Knipex Self-Adjusting Crimping Pliers for wire ferrules with lateral access burnished, with multi-component grips 180 mm 97 53 04

Product Information

From the inexpensive crimping pliers for wire ferrules as a light and compact hand tool to the compact and universal Multi-Crimp® crimp system pliers and the semi-automatic, electrically driven eCrimp system pliers with over 1,500 interchangeable, different crimp inserts – with KNIPEX you have all the options at hand.

Unlike the Preciva HSC8 6-6 that has six-sided jaws, the Knipex 97 53 04 pliers have 4-sided crimping slot. This means that they crimp end sleeves to a square shape, which fits better into square terminal connectors. But there is a hex-style version of the Knipex ferrule crimping tool. Its product number is 97 53 14. It compresses ferrule tubes to a hex shape, suitable for round connectors. Bigger crimping capacity Overall, ferrule sleeves or bootlace terminals are essential for securing the loose ends of stranded electrical wires. They give flexible wire the properties of solid core wire at the connection point, effectively improving electrical conductivity. So, what factors should you consider? Factors to consider when buying a ferrule crimper for cable 1. Crimp profile Although the Wiha ferrule crimper is more expensive than many ferrule crimping pliers brands, its price is worth the quality you get. The tool has a solid construction, fits well in the hands, and makes crimping fun. You will not hear parts moving inside when you shake it as you would on some cheap generic brands. Cable ferrule crimping pliers operate either through a ratcheting or non-ratcheting action. The best ferrule crimpers are those that utilize a ratchet mechanism to compress the crimps.

FAQs

This German-made ferrule crimper has a hexagonal compression slot that is what you need when compressing ferrules for round terminals. The crimper’s mechanism offers good leverage that makes the work of crimping ferrule less stressful. Outstanding feature In fact, because ferrule crimpers with a ratcheting action require less hand strength, they are called labor-saving crimpers. They are so easy to use even for teens and the elderly. 3. Crimp capacity

A wire ferrule is a thin metal tube for terminating the ends of a stripped stranded wire. It holds the strands together to keep them nice and neat. Unlike regular crimp connectors, ferrules do not provide different connector configurations. They are only metal sleeves for managing the stripped ends of flexible cable to keep the strands from fraying out when inserted into terminals. Crimped ends of stranded flex wire To connect a conductor and a connector to each other, they must be positioned in the appropriate crimping profile. For some crimp connections, there are positioning aids available, which simplify the insertion of the plug into the crimping tool. Instead of the typical extra spacers, the ratcheting action of the Preciva tool has an adjustment cam for tweaking the pressure the jaws apply onto the ferrule sleeves. This feature helps you control the pressure you exert on the ferrule tubes to prevent the jaws from puncturing them or not crimping tight enough. It also increases the usability of the tool even on small ferrules such as the 24AWG size. Another important consideration when shopping for a wire ferrule crimper is the crimp capacity. This is the range of wire gauges the crimping pliers can accept. Crimping pliers for wire ferrules exert pressure on both ferrule and wire from all sides via four crimping parts. In this way, when choosing the right crimping profile or using an automatic crimping tool due to plastic deformation, a mechanically firm and electrically secure connection is achieved.Unless you work with specific wire gauges, I suggest you select a ferrule crimper that can press ferrules on general wire sizes. Ideally, a crimping range of 10AWG to 20AWG should suffice. The Wiha is another spectacular ferrule crimping pliers from Germany. It accepts wire ferrules of sizes 0.08mm2 (28 AWG) to 16mm2 (5 AWG).

The template guide swivels smoothly so that you can align any of the three holes with the crimping slot. The size range of the holes is 28 – 22 AWG, 20 – 16 AWG, and 14 – 12 AWG. I like the template because it eliminates any chance of squeezing the insulation on ferrules. I recommend that you get the kit instead of the bare tool, especially if you are just getting started with ferrules. It will save you from the hassle of having to buy the wire ferrule sleeves separately. The Knipex 97 53 04 crimp tool is generally easy to use. It has a smooth ratcheting action and it is easy to adjust the crimping slot by hand to accept various wire sizes. The tool is also comfortable in the hand. The plastic on the handles feels a bit smoother and gentler. Downsides The only downside of the Knipex is the prohibitive price. It costs at least 5 times more than the Preciva but it is really worth the price. You get what you pay for. If you do not manage the strands of a flexible cable properly after stripping it, you could be shooting yourself in the foot. The loose wire strands can get into the wrong places in your circuitry and short things up.Ferrule terminals also protect stranded wire ends against fraying, facilitate termination, and aid in wire identification. They also ensure compliance with wiring standards, especially in Europe where it is mandatory to use bootlace terminals on stranded electrical wires.

The best tool for installing wire ferrules is a wire ferrule crimper tool. This is a special type of pliers designed for compressing ferrules to secure the strands of a stripped flex cable. You can learn more about ferrule crimpers and how to install them in this article. How to Choose the Best Ferrule Crimper Pliers You will also find multi tool crimping pliers such as the Knipex multicrimp that come with a range of interchangeable die sets for crimping various types of bootlace ferrules and regular crimp connectors. Versatility is also demonstrated by models that, in addition to crimping, are also suitable for stripping and cutting cables. And innovative support. For example, universally adjustable positioning aids or electronic displays for wear and the necessary calibration for crimping pliers for very sensitive crimp connections.Unlike the preciva which only offers a crimping capacity of 20 – 10 AWG (0.25mm2 to 10mm2), Knipex crimper can compress ferrules of sizes 0.08mm2 to 16mm2 (28 – 6 AWG). This means that the tool is more suitable for industrial applications where the wire sizes may vary from very small to large. For example, you will find 24 AWG stranded cables or above in the communication lines of industrial PLC machines and you would need the Knipex to crimp them. Ease of use A poor connection can easily become a high resistance point in your circuitry, especially for high currents. And with high electrical resistance, comes high electrical losses because of heating. If the connection point overheats, it could burn or deteriorate the circuit board and the nearby electronic components. Sometimes a loose electrical connection can cause a fire. Like the Preciva, the Knipex crimper for end sleeves uses a ratcheting mechanism to close the crimping jaws. However, the ratcheting is a lot smoother and amplifies your force a lot better. This allows you to do most of the crimping with one hand, including large conductors. Square-style crimper
