SN37A12A

Barrel - Audio Connectors

SN37A12A is a type of barrel-type audio connectors widely used in audio systems. It consists of a male and female component, and its design features two locking nuts that provide a reliable connection between the components. In addition, the insulation provided by the resilient rubber seal ensures electric insulation and acts as a vibration damper for noise reduction.

The male part of SN37A12A consists of a barrel pin and an insulation sleeve made of rubber. The barrel pin is made of brass which conduct electrical current efficiently and is further plated with gold or silver to resist corrosion. The insulation sleeve consists of rubber grommet, which prevents the wire from making contact with the metal barrel pin and ensures the safe and reliable operation for long term use.

The female part of SN37A12A consists of a socket-body with two ring-threaded locking nuts. The socket-body provides an electrical connection between the collar and the barrel pin. The inner and outer rings of the locking nuts ensure that the components are securely interconnected. The insulation sleeve made of rubber further helps in vibration dampening and electric insulation.

SN37A12A audio connectors are commonly used in audio systems such as amplifiers, speakers, headphones, microphones, and other audio equipment. In these systems, the male component is typically connected to an audio signal source such as a line-level voltage output, while the female portion may be connected to a speaker drivers or headphones. The locking nuts of the SN37A12A connectors help to ensure a reliable and secure connection between the components, while the rubber insulation helps to protect the device from unwanted interference.

SN37A12A audio connectors can also be used in other applications requiring secure electrical connections. Other applications may include medical devices, power connectors, industrial automation systems, or in any application where secure and reliable connections are required.
