Test Connectors

In many industries, the use of electronics – from communication networks to automated systems – is more common than ever before. To ensure that maximum performance is always maintained no matter the application, test connectors take on an essential role. With these components, it is possible to test for (and identify) problems that can affect reliability and even personal safety.

At RS, we are committed to supplying high quality electrical components for a wide range of applications. Our test connectors, plugs, clips, and probes includes options from leading manufacturers such as Mueller, Pomona Electronics and Smiths Interconnect Americas, Inc. It means that you are sure to find the exact specifications you need when you choose RS.

What are test connectors?

The failure of a circuit or network can have major consequences for a business. That is why test and measurement equipment, such as oscilloscopes and multimeters is so essential. Test connectors and plugs are used in conjunction with these items. Without such items, it becomes harder to locate problems safely and accurately when (and even before) they occur.

Test clips, connectors, plugs, and probes are versatile components. Using them, you will be able to ensure that other components in a circuit or network are performing as expected and needed.

What are banana plugs and connectors?

One common single-wire connection device for testing and measurement is the banana plug (or connector). The name is derived from the distinctive shape of this type of test connector. With a banana plug, you can safely connect wires to equipment. 4mm is the most common version.

For high voltage applications (including mains connections) a sheath protects the exposed metal contact for user safety. But, if the voltage requirement is lower such as in handheld devices, the bare pin remains unshrouded. The type that you need will always depend on its application.

What types of test connectors do we supply?

As we appreciate the varying and complex needs of industrial applications, RS can supply you with the most appropriate type of test connector. Our most popular test plug, clip, or connector categories include:

4mm test connectors

In most applications, it is often 4mm test connectors – particularly banana plugs – that are used. The measurement refers to the diameter of the metal pin that forms the connection. This can be connected directly onto a wire or component, or it can be inserted into a compatible jack. 4mm test plugs can also be stackable. This can be useful for creating multiple connections or joining many leads.

Spring test probes

For testing and measuring automated systems, you may need to consider one of our spring test probes. This type of test connector is designed to connect with various points on a printed circuit board (PCB), component, or other electronic systems. With several tip styles and spring pressure options available from RS, it is easy to find the spring test probes that you need.

It is common for this type of connector to be used in a test station as part of a larger production line, for example.

Test alligator clips

To make a connection without a permanent solution such as soldering, test alligator clips are an excellent and essential option. These test clips – also called crocodile clips – get their name from their design. The hinged, serrated ‘teeth’ clamp onto a battery or another component to create a temporary electrical connection.

In our test connectors range, you can select test alligator clips in different sizes and materials to match your specific requirements.

What are test connectors used for?

In the first instance, test connectors are used (as the name infers) to test or measure electrical connections and components. Used with equipment such as multimeters and oscilloscopes, test connectors make contact with one or more points on a system or circuit board. By doing this, it enables you to measure performance, diagnose faults and identify issues.

Test plugs, clips and connectors are a vital part of a professional electrician’s inventory. But the need to test and measure is present in numerous industries – and can be diverse in the desired outcome. Here are some examples of environments in which test connectors are used:

• Laboratories and other educational purposes
• Consumer electronics e.g. TV and audio devices
• Automotive testing and diagnostics
• Automated plant, production, or assembly lines
