Product Questions
What is the difference between W, D, and T series ferrules?
The short answer is that there are three different standardized color sequences for wire ferrules. Here is a complete breakdown of the three color sequences:
W Series: which standard for Weidmuller, since that brand popularized this particular color sequence.
D Series: which stands for "DIN" or Deutsche Industrie Norm style. AKA the original color series used when these ferrules were invented.
T Series: which stands for the French "Telemecanique" color style. If you are working with ferrules currently and are trying to match an existing series that you might have, then feel free to provide us with the colors for the wire sizes and we can help you select the appropriate series.

What is the difference between Easy Entry vs Standard ring and fork terminals?
The different series are different sets of colors. Easy Entry terminals have their insulation formed into an hourglass shape to help funnel the wire into the terminal and prevent the wire from fraying.
What is the difference between UL Recognized and UL Listed?
UL Listed means a complete product, like a computer or a machine, has been rigorously tested by a safety company (UL) to meet safety standards for things like electrical shock and fire. It's a sign you can trust the product is safe.
UL Recognized applies to individual parts, like a cable tie or button, that meet safety standards for their limited function. These parts help ensure the final product (like a machine) can be UL Listed. For more information, check out our blog post.

How do I pick the correct tool to crimp my wire ferrules, terminals, connectors?
Wire Ferrules: Hand Operated Crimping Tools for wire ferrules tend to fall in specific industry standard AWG ranges for crimping smaller AWG ranges, medium AWG ranges, and large AWG ranges. Here are some of the standard ranges for crimping tools you will find on the market:
- 28 to 10 AWG
- 24 to 10 AWG
- 22 to 10 AWG
- 10 to 6 AWG
- 10 to 4 AWG
- 4 to 1 AWG
- 8 to 1 AWG
- 1 AWG to 3/O AWG
- 4/0 to 300 MCM
So, if you purchase a tool that has a range of 24 to 10 AWG, it will have separate slots for each of the AWG sizes in that range. Caveat being that some of the smaller sizes might share a slot. Take the FD2410N crimping tool for example. It crimps in the industry standard “trapezoidal” crimping style and has six crimping slots, from smallest to largest:
- 24/22 AWG (0.25mm2/0.50mm2)
- 20/18 AWG (0.75mm2/1.00mm2)
- 16 AWG (1.50mm2)
- 14 AWG (2.50mm2)
- 12 AWG (4.00mm2)
- 10 AWG (6.00mm2)
Common crimping profiles: square, trapezoidal, hexagonal, figure-eight, c-shape. The vast majority of these tools have ratchet mechanisms to allow for crimping assistance. You can still find traditional crimp pliers but they are less common in today’s market. The primary tool used for terminals and ferrules is a crimping tool. These tools are specifically designed to precisely compress the metal barrel of the terminal or ferrule around the wire, creating a secure and reliable connection.

What are "True AWG" ferrules and how do they differ from standard ferrules?
Because wire ferrules are a European invention, they are made according to the European metric wire. This can sometimes lead to excess room between the ferrule and the conductor. Once crimped, your ferrule will get the “dog ear” effect. This is where the excess material on the ferrule folds to one side creating a “dog ear” or lip. Ferrules Direct offers a unique line of "True AWG" ferrules for several of the larger AWG sizes. True AWG ferrules are custom-manufactured to better match the American Wire Gauge (AWG) system. For proper fitment it is suggested that you measure the naked conductor of your AWG wire and compare that to the “D1” interior dimension of the True AWG ferrule. At least +/-1mm of inner spacing is recommended. For more information on AWG, please refer to our blog post.
How do I ensure proper connection with male and female connectors?
When using quick disconnects or bullet connectors, it's important to verify that the male and female components are the same size. Size mismatches can lead to loose or insecure connections.
