Barrel Audio Connectors are electrical connectors that provide a physical interface between two devices. The most common type is the 285L connector. It is widely used in many fields, including consumer electronics, audio/visual equipment, communications equipment, automotive audio, and industrial instrumentation.

285L Connectors

The 285L is a two-piece connector that consists of a male or female plug and a receptacle. It has a metal body with an insulating material between its two contact pins. The pins are connected with a short flexible metal tether and a molded plastic cover. The 285L connector comes in various sizes, ranging from 2.5 mm to 30 mm, and its weight varies from 1.20 g to 113 g.

285L Application Field

The 285L connector is used in a variety of applications, including:

• Audio and video signal transmission
• Automotive audio systems
• Industrial instrumentation applications
• Military and aerospace electronics
• Telecommunications
• Computer systems and peripherals

Working Principle

The two contacts within the 285L connector are designed to provide a reliable electrical connection. The contact pins are designed to create an electrical connection when the plug is inserted into the receptacle. This is often called the “make-break” connection because the contacts will make the connection when the plug is inserted and will break the connection when the plug is removed.

The contacts also feature a spring-loaded mechanism that allows for a secure but flexible connection that reduces the risk of damage caused by vibrations or shocks. The contacts are also designed to provide an extremely low contact resistance, which helps to reduce signal loss and prevent interference.

The 285L connector is also designed to operate in both on-board and off-board applications. This is possible due to its shielded design, which helps reduce EMI and RFI interference and ensures a reliable connection.
