Electrical Flying Leads: What Are They?

what is a flying lead in electrical

Flying leads are electrical connectors that offer flexibility and cost-effectiveness for simple applications. They are typically easy to understand and implement, but there is room for error when connecting the leads. Flying leads are often compared to M12 connections, which are circular connectors with a standardized size and configuration. M12 connections are commonly used in industrial automation and control systems, providing secure and reliable electrical connections in harsh environments. Understanding the differences between flying leads and M12 connections is crucial when choosing liquid process instrumentation as it impacts performance, durability, and maintenance, especially when dealing with corrosive liquids.

Flying leads are simple to understand and implement

One example of their use is in connecting a TV to antenna sockets with a coaxial connection. These coaxial fly leads offer a 90dB screening rate with dense braiding and extra-strong shielding foil for protection from electromagnetic interference. They provide excellent picture and sound quality, flexibility, and ease of routing through entertainment cabinets.

Another application of flying leads is in liquid process instrumentation. They are particularly useful when handling corrosive liquids, offering a cost-effective solution with custom wiring lengths. Flying lead connections are also beneficial in harsh environments, providing electrical conductivity and durability.

ICON Process Controls offers a range of instruments with M12 connections, ensuring optimal performance and reliability in liquid process instrumentation. However, flying leads have their advantages, offering lower initial costs and flexibility for simpler applications.

While flying leads are generally easy to implement, there is room for error during the connection process. In contrast, M12 connections are keyed to prevent improper wiring setups. Nonetheless, flying leads remain a popular choice due to their simplicity, flexibility, and cost-effectiveness for basic applications.

They are cost-effective for simpler applications

Flying lead connections are a cost-effective solution for simpler applications. They are easy to understand and implement, offering flexibility and customisation for specific needs.

Compared to M12 connections, flying leads have a lower initial cost. While M12 connections are standardised and keyed to prevent improper wiring setup, flying leads offer greater flexibility and customisation. This customisability makes them ideal for simpler, less demanding applications that do not require the same level of standardisation as more complex setups.

The cost-effectiveness of flying leads is particularly advantageous for those on a budget or for projects where cost is a primary consideration. They are a popular choice for applications where the performance and durability offered by M12 connections may be excessive or unnecessary.

Additionally, flying leads can be tailored to meet the exact requirements of a project, ensuring that resources are used efficiently and effectively. This customisability also allows for optimal performance and reliability, even in the handling of corrosive liquids.

However, it is important to note that if a sensor or connection cable fails on a flying lead, both items must typically be replaced as they are permanently connected. In contrast, M12 connections allow for the isolation of the sensor and cable, reducing replacement costs.

They are customizable for specific needs

Flying lead connections are customizable for specific needs. They are versatile and can be tailored for specific applications, such as sensors, power, or industrial communication protocols, meeting the requirements of multiple sectors. They are ideal for applications where custom wiring lengths are needed.

Flying leads are typically used in prototyping, testing, or temporary installations, where connections change frequently. The term "flying" indicates its ability to be moved or adjusted freely. They are also used when solid and highly reliable connections are required, eliminating the possible movement of connector pins and the effects of vibration.

Flying leads are simple to understand and implement, and they are cost-effective, especially for simpler, less demanding applications. They are also well-suited for less harsh environments, offering flexibility and ease of installation.

However, it is important to note that flying leads are less secure and durable, particularly in corrosive environments. In such cases, M12 connections may be preferred for their superior reliability, durability, and ease of maintenance.

They are suitable for connecting a TV to antenna sockets

A flying lead is a type of cable assembly that is used to transmit signals or data between two devices. In the context of television and antenna connections, a flying lead, also known as a flylead, is a removable connecting cable that serves as an important component of any television antenna system.

Flying leads are suitable for connecting a TV to antenna sockets, enabling the transmission of audio and video signals to the television. They are typically used to connect from a TV antenna wall outlet to the TV, facilitating the reception of broadcast channels.

These leads usually have a male aerial plug at each end, connecting to the female socket on the TV and the wall outlet. The male-to-male configuration ensures a secure and compatible connection between the two devices.

Flying leads offer flexibility and cost-effectiveness, making them a popular choice for simpler applications. They are easy to understand and implement, although there is a possibility of error during the connection process. It is important to select a high-quality flying lead to ensure reliable performance, especially for digital TV systems.

When choosing a flying lead for your TV-to-antenna connection, it is essential to consider the specific requirements of your setup, including the length of the cable, the quality of the connectors, and the compatibility with your TV and antenna system.

They are not required for metal back boxes

A flying lead is a wire that connects the earth terminal of a socket to a metal back box. It is used to ensure that the back box is earthed, which is important for electrical safety.

While using a flying lead is considered best practice, it is not always required by electrical regulations. For example, if the back box has at least one fixed lug, a flying lead is not necessary. This is because the box can be adequately earthed through the earthing straps and eyelets of the socket outlet and the fixing lugs on the box.

In addition, if the back box is made of plastic, there is no need for a flying lead as there is nothing to earth. In this case, even if the box has an earth terminal, a flying lead is not required.

It is worth noting that modern regulations require an earth connection to every accessory, even if it doesn't need it. Therefore, when replacing plastic switches with metal ones, it is important to ensure that an earth connection is present. However, very old installations may not have earths on the lighting, and bodge jobs may have not connected them properly.

Overall, while flying leads are not required for metal back boxes in all cases, they are often used as good practice to ensure adequate earthing and electrical safety.
