Stereo Connectors

Designed for use in audio equipment.

Receptacles with an off (Normally Open) circuit position turn equipment on when a device is plugged in.

Receptacles with an on (Normally Closed) circuit position turn equipment off when a device is plugged in.

Receptacles with a shunt divert current from one device to another when a connection is made. In a stereo, the speakers are the default connection to the sound system. When a pair of headphones is plugged into the stereo’s receptacle, the shunt diverts current, and the audio, to the headphones.

Panel-Mount Stereo Connectors

Stereo Connector

Plastic Cap

Connect audio equipment. These connectors mount to panels of any thickness, as long as you drill a mounting hole first.

Normally open connectors turn equipment on when a device is plugged in. Normally closed connectors turn equipment off when a device is plugged in.

Protect connectors when not in use by covering them with caps (sold separately). Caps are tethered, so you can open them in any direction for access from any angle.

DMX Connectors

Plug

Socket

Replace damaged connectors on lighting cables that are commonly used for movie and stage lighting, as well as interior building lighting. They can also be used to make your cables longer. These connectors are compatible with equipment that have five-pin XLR connections. They lock together, so they won't accidentally unplug.

Barrel-Style DC Connectors

Made with industry standard barrel-style ends, these connectors carry DC power between electronic devices and power supplies.

Housing Connection—Pair connectors that have the same type of housing connection. Push-in connectors are quick to connect and disconnect. Screw-together connectors take longer to connect, but are more secure. They’re good for preventing power loss if vibration might loosen the connection or the connector could get yanked out.

Wire Connection—Choose based on your application. Solder connections are the most secure and permanent connection.

IP-Rated Connectors—Create a sealed connection when the plug and socket, receptacle, or adapter are also IP rated. All are dust tight, even when there’s continuous airflow. IP68-rated connectors have been tested by the manufacturer to withstand immersion in water for more than 30 minutes.

Receptacles—Mount them in a panel. Receptacles with an off (Normally Open) circuit position turn equipment on when you plug in a device.
