With the ever-growing technology advancement, more and more events in our daily lives call for small materials to work. This is where mini coaxial cables come into play. 

For example, they are in use in the medical, aerospace, work in a house, analyst, defense industries, and more. Here is a basic guide on mini coaxial cables to get you familiar with them.

Understanding Mini Coaxials Cable Physically

Coaxial cables are only 0.20 mm in diameter. However, don’t let their small size fool you. They are really tiny but can successfully send important signals. Also, they are a great alternative to standard RG-type coaxial cables, which are too thick and large.

Because of their small size and flexibility, you can use them for mobile phones, imaging, spyware, and more. With proper connectors, mini coaxial cables can send very high frequencies, reaching up to 6GHz. 

What Are Mini Coaxial Connectors?

Mini Coaxial Cable Connectors

To use mini coaxial cables correctly, you must use them with mini coaxial cable connectors. Mini coaxial cable connectors connect mini coaxial cables to other pieces of technology or other mini coaxial cables. They can transmit very high frequencies. Some mini coaxial cables can transmit frequencies up to 6GHz. 

How To Put A Mini Connector Onto Mini Coaxial Cable

Here is how you prepare a mini coaxial cable and compress a mini coaxial cable connector onto It. 

  1. First, trim the tip of your mini coaxial cable with a pair of cable cutters.
  2. Next, take your prep tool. Insert the tip of your mini coaxial cable into the clamp of your connector tool and wound it around a few times as it is closed around the tip of your mini coaxial cable. 
  3. With a quarter-inch of your mini coaxial cable inner wires exposed, take your mini coaxial cable connector and insert your mini coaxial cable into it. 
  4. Then, with your compression tool, tighten your mini coaxial cable connector firmly onto your mini coaxial cable’s tip. 

Customize Your Own Mini Coaxial Cable

Whether you want to apply the cable in digital imaging, patient monitoring, ultrasound, or as antenna leads, you must consider one with high flex life, high temperature & fluid and chemical resistance, and low noise.

Using the proper center conductor, dielectric, shield, and sheath, we can reduce the cable size without influencing signal integrity.

Our conductor materials include bare copper, plated copper, and high-strength alloy with improved flexibility. Also, you can choose the conductor sizes, miniature (24-32 AWG), Micro-Miniature (34-44 AWG), or Ultra Micro-Miniature (46-50 AWG), to meet the demanding requirements of the medical and industrial fields.

Considering electrical, temperature, and size conditions, we select dielectric Materials from Polypropylene, FEP, PFA, and ETFE. As for the shield, braid, spiral, and aluminum foil are available, typically designed for 90% minimum coverage.

Also, according to the application, we will choose the proper jacket material.
