Most frequent questions and answers

Each connector has distinct qualities and features, and selecting the right one ensures efficient power or signal transfer. There are a few factors to take into account while choosing an industrial connection.

Weight Gauge

Each connector package is made to fit a certain wire gauge. To avoid increasing electrical resistance at the connecting site, always use a connector that precisely matches your wire gauge.


Outer Diameter of Cable

Take note of the cable’s outside diameter, much like the wire gauge. It is crucial to select a housing (connector) with a large enough inner diameter so that the cable may fit in correctly. Cable sizes vary depending on specifications.


Number of Contacts

Ensure that the connector and cable both have the same number of contacts. The majority of standards bodies, including UL, NEC, and NFPA, forbid ganging numerous wires into a single termination or crimp connection.


Voltage and Current Rating

Each cable and connector is designed for a certain range of voltage and current. Select a connector for your cable that is rated for the same voltage and current range.



Specifications for the cable alone are not enough to choose an industrial connection. Before choosing a connector, it is advised to consider the surroundings because some connectors shouldn’t be utilized under challenging conditions.


Rigidity and Flexibility

Some applications are very prone to bending and vibrations. To accommodate motions and prevent deterioration, it is crucial to use a flexible connection.


Chemical Resistance

The connectors may occasionally be vulnerable to chemical interactions. Because chemicals can harm and impact connectors, specialized connectors made of stainless steel or PVC can be used for longevity.

The rate of development in the commercial sector has frequently exceeded that in the military sector, leading to more potent capabilities at lower costs (take communications, for instance).

Military applications look for COTS (commercially available off-the-shelf) technology that may meet their strict requirements so they can get some of the benefits.

The military standard for D-sub connections is M24308. Ruggedized tablets, laptops, voice and data communication systems, GPS receivers and hubs, and mobile power supply units are examples of devices that often use M24308 D-sub connections.

Mil-COTS connections must be able to survive extreme temperature changes, corrosion, high impact shock, and other combat-related situations. They are made to work at a variety of temperatures.

Medical device power, data, and control signals are sent to and from medical devices via medical connection systems (cables and connectors). They can be found in a variety of clinical settings, including those involving surgical tools like hand tools, therapeutic equipment, and diagnostic tools like EEG, ECG, EKG, and EMG machines. They are frequently found on transportable medical equipment.

Medical connections must endure a variety of medical sterilization procedures, such as chemical, gamma, autoclave, Sterrad, EtO, and autoclave. Additionally, a medical connection system needs to be protected from contaminants like dust, water, and other risks.

A high mating cycle, an IP rating of up to IP68, strong EMI/RFI performance, and rapid connect/disconnect capabilities are additional criteria. There can be particular specifications for some medical uses.

Be careful while choosing the material because it might affect durability, weight, and price. In comparison to many other materials, brass connectors with nickel or chrome plating are often more wear-resistant and have longer lifecycles. Aluminum connections could be a choice if weight is a concern.

Plastics are a good option for projects that will only be used once or twice. Make sure you carry out sufficient testing to verify that plastic will survive the end use application if you are contemplating it.

Make sure your connection can resist the sterilization procedures the end user uses if it is being utilized in medical applications. Stainless steel may be necessary for use in the food industry or in strongly corrosive conditions. When choosing a material, don’t compromise on reliability for price.
