Bring power into electronic devices while protecting them from harmful electromagnetic interference (EMI). All of these connectors are compatible with standard IEC power cords. 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. When selecting a connector, make sure the current is at or slightly above the requirements of your device for the best EMI-filtering performance.

All of these connectors meet U.S. and international standards for safety. They also meet UL 94 V-0, which means they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. Rated IP40, these connectors prevent objects larger than 1 mm, such as wire, from making contact with a live circuit and shocking you. They 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.

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 quick-disconnect terminal connections. Quick-disconnect terminal wire connections are faster to wire than 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.

Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI). Even with their built-in power supply, these connectors have the same overall footprint as those without a power supply. All are for use with standard IEC power cords. Commonly used to convey power from wall outlets, you won’t have 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.

For fast wire connections, these connectors have quick-disconnect terminals. The terminals slide together with the quick-disconnect terminals on your wiring and are easily disconnected by hand, but still provide a strong hold.

All of these connectors use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. If you exceed the maximum voltage or load, the connectors will shut down to protect both the power supply and the connected device. They also meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.

These connectors meet U.S. and international standards for safety. They also meet UL 94 V-0, which means they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. All have Class I shock protection—they're insulated and have a protective ground to prevent electrical shocks.

Maximum output noise is also known as ripple noise. When power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this noise won't affect most applications, it can interfere with other signals in extremely sensitive audio equipment and high-precision measuring and testing equipment. The lower the output noise, the less interference it creates.

Power factor and efficiency give you a sense for how efficiently these connectors draw AC power and convert it into DC power, which ultimately affects your operating cost. The closer the power factor is to 1, and the higher the efficiency percentage, the lower the operating cost. The more efficient the power supply, the cooler it runs.

Power electronics in damp environments while protecting them from electromagnetic interference. The filter on these connectors reduces electromagnetic interference, which could damage components and cause your electronics to behave erratically. These connectors pair with industry standard cords often found on electronic devices. Wire them using the quick-disconnect terminals, which slide together with matching terminals on your device for a secure fit that can still be pulled apart by hand and removed for repairs. The terminals are on the back of the connector, so the wiring stays inside your device.

Class I shock protection means these connectors have insulation and a protective ground. They meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping. They’re also UL and C-UL recognized components, CE and ENEC marked—they meet U.S., Canadian, and European safety standards. They are rated IP65 for protection from dust and rinsing.

When selecting a connector, make sure the current is at or slightly above the requirements of your device for the best EMI-filtering performance. These connectors require fuses (sold separately) to prevent short circuits and circuit overloads from damaging your devices.
