Circular Connectors

Circular connectors are named for the circular shape of their pins and receptacles. They are a widely preferred connector type for people who need reliable electrical continuity in harsh, environmental conditions. The level of durability for this connector type is due to the design and components used, such as circular contact pins and insulators made from polyphenylene sulphide (PPS), dimethyl penten (DMP), thermoplastic elastomer (TPE) and heat resistant polypropylene.In many ways circular connectors are an ideal choice in electronics engineering. They are available in a variety of sizes and styles, plus they require little effort to install and is easy to make a connection with. The plug and socket connectors are also usually designed to be interchangeable between different brands. Additionally, circular connectors come in either shielded or unshielded versions, with the shielded currently being the more popular option.

7281-8PG-300

The 7281-8PG-300 is a popular circular connector used for electrical continuity in a variety of environments. This 8-pin circular connector is made from PPS and polypropylene, giving it extra rigidity and high temperature resistance, making it suitable for harsh environments such as in automotive and industrial applications. The 7281-8PG-300’s pins and receptacle, which are typically air tight, are designed to be resistant to vibrations, impact and chemical spills. The insulation materials used is also resistant to fuel, lubricating oil, antifreeze, coolant and salt-water.

Working Principle

Circular connectors consist of two mating parts: the plug and the socket. The plug is composed of one or more pins, while the socket contains the mating contacts (receptacles).The 7281-8PG-300 has 8 pins making it a 8-pin circular connector. It is a single-ended type wiring termination, meaning one end of the connector is the Socket while the other is the Plug. Upon connection, the Plug and Socket are lowered perpendicularly into each other, where they meet and lock into each other. The connection is made when the pins and receptacles pass through the contact slot of the connector. Once the connection is properly secured, it will be able to resist vibrations, shock, temperature, etc. The connection will also be able to conduct electricity from the source to the device. The element which is responsible for the conducting of electricity is known as the gold and silver alloy contacts of the 7281-8PG-300.

Application Field

The 7281-8PG-300 is suitable for harsh environmental conditions that demand higher temperature resistance and stability. It is commonly used in:- Automotive applications, such as for car radios, starter switches, door locks, exterior lighting and engine control systems- Industrial applications, such as for factory automation systems, medical equipment, industrial machinery, and test and measurement equipment.- Communication applications, such as for interface systems in telecom equipment.The 7281-8PG-300 is also known for its versatility and reliability in a variety of other applications. It serves as a reliable electrical interface connection between two pieces of electrical equipment.
