Pair these connectors with standard IEC power cords to bring power into or out of your electronic devices. Often used to convey power from wall outlets, there’s no need to wire your devices to an external power source. Instead, wire these connectors into your device with the terminals on the back of each connector. Most meet U.S. or international standards for safety.

Receptacles are often installed in electrical devices. Most also include shock protection. Class I shock protection means they're insulated and have a protective ground to prevent electrical shocks. Class II shock protection means there are two levels of insulation to prevent electrical shocks. Male receptacles are commonly used to bring power into an electronic device. Some accept a fuse to prevent short circuits and circuit overloads from damaging your devices. The fuses are sold separately. Screw-on connectors mount to devices with any panel thickness, as long as you can drill mounting holes into the device. Snap-in connectors mount to devices with snap-in tabs—no fasteners needed—but require a specific panel thickness and a precisely cut hole for secure mounting.

Solder terminal wire connections are more secure than screw and quick-disconnect terminal connections. Quick-disconnect terminal wire connections are faster to wire than screw and solder terminal connections. The terminals slide together with the quick-disconnect terminals on your wiring and are easily disconnected by hand, but still provide a strong hold.

IP-rated connectors meet standards for protecting you from making contact with a live circuit. The larger the first digit, the smaller the object it protects against. An IP20 rating means fingers and other objects larger than 12.5 mm can't get in. Connectors with a UL 94 rating have passed one of UL's flame tests. UL 94V0 means they self-extinguish within 10 seconds if they catch fire and won’t spread flames from dripping.
