Electrical Connectors

IEC Connectors

Pair these connectors with standard IEC power cords to bring power into or out of your electronic devices.

IEC Connectors with Power Switch

Switch your device on and off without needing a separate switch. These connectors work with industry standard cords often found on power supplies, appliances, and other electronic devices.

Harsh Environment IEC
Connectors with Power Switch

Rated IP67, these connectors create a dust- and watertight seal where they fit into the housing of power supplies, appliances, and other electronic devices. Instead of hardwiring your devices, these connectors let you plug in a standard IEC power cord and turn the power on and off with a built-in switch.

EMI Filtering IEC Connectors with Power Switch

With a built-in switch, these connectors run power to appliances, power supplies, and other electronic devices while also filtering damaging EMI (electromagnetic interference).

EMI Filtering IEC Connectors

Bring power into electronic devices while protecting them from harmful electromagnetic interference (EMI).

EMI Filtering IEC Connectors
with Integrated Power Supply

Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI).

Harsh-Environment EMI Filtering IEC Connectors

Power electronics in damp environments while protecting them from electromagnetic interference.

Combination Inlet/Outlet IEC Connectors

Send power to your device using the inlet, then route power to another device through the outlet—all with standard IEC power cords.

Sanitary Electric Multipurpose Connectors

Reduce the number of electrical connections in sanitary areas, such as food plants—these connectors combine Ethernet, a power cable, and wire for signals into a single connection point.

Data, Audio, and Video Connectors

Unshielded Crimp-On Data Connectors

Use an Ethernet cable crimper to terminate these plugs.

Shielded Crimp-On Data Connectors

Protect sensitive equipment from electromagnetic interference.

Panel-Mount Ethernet Connectors

Install these connectors in a panel cutout to create a port for transferring data.

Push-to-Lock Data Connectors

Push these connectors together for secure Ethernet connections that are quick and easy to connect and disconnect with just one hand. You’ll know when the plug and socket are locked in place when you hear a click.

M8 Ethernet Connectors

A threaded M8 end on these connectors keeps contaminants out and withstands vibration better than RJ45 ends on traditional Ethernet cords.

Shielded Snap-On Data Connectors

Protect equipment from electromagnetic interference.

Latching Washdown RJ45 Connectors

Protect connections in washdown environments while maintaining access—these RJ45 plugs and adapters latch together securely, yet quickly detach.

Food Industry Micro M12
Screw-Together Ethernet Connectors

FDA compliant to safely touch food and threaded for a tight hold, these connectors won’t vibrate loose as they send high-speed data to sensors and other automated devices in food, beverage, and pharmaceutical plants.

Micro M12 Screw-Together Ethernet Connectors

Unlike traditional RJ45 connectors found in data centers, these connectors stand up to rugged industrial environments since they tightly thread to devices with M12 connections, sealing out contaminants and resisting shaking loose from vibration. Use them to transfer high-speed data between sensors, switches, computers, IO modules, programmable logic controllers (PLCs), and other equipment.

Screw-Together Wet-Location
HDMI Connectors and Cords

Audio/video HDMI connectors and cords are rated IP67 when mated.

Data, Audio, and Video Adapters

Video Adapters

Alter DVI, DisplayPort, and HDMI connections.

Panel-Mount DisplayPort Adapters

Connect two DisplayPort cords of the same gender and connection type.

Panel-Mount HDMI Adapters

Mount these adapters in a panel cutout.

HDMI Adapters

Convert one HDMI size or style to another.

USB Adapters for Keystone Wall Plates

Snap these adapters into keystone wall plates to transfer USB data through walls or partitions.

Data-Blocking USB Adapters

Protect your computer and other sensitive equipment against data breaches and malware from unknown USB devices.

USB Adapters

Connect mismatched USB cords and devices with these adapters.

Cords

Electronic Equipment Power Cords

Use these cords with computers, lab equipment, and office machines that have IEC connections.

International Electronic Equipment Power Cords

All cords have a country-specific plug on one end and an IEC socket on the other end.

Locking International Electronic
Equipment Power Cords

Create a vibration-resistant connection—the socket on these cords securely locks onto any male receptacle and will not detach until manually unlocked.

Sure-Grip Electronic Equipment Power Cords

Also known as hospital-grade cords, these cords have an extra-tight connection to prevent them from detaching. The plug is marked with a green dot.

Locking Electronic Equipment Power Cords

Create a vibration-resistant connection—the socket on these cords locks onto any male receptacle and will not detach until manually unlocked.

Shielded Electronic Equipment Power Cords

The shielding blocks signal interference from nearby equipment and devices.

Electronic Equipment Cord Splitters

Power multiple devices from one power source.

Sure-Grip Coiled Electronic Equipment Power Cords

Tug these cords to full length, and they’ll stay plugged in. Also called hospital-grade cords, they form an extra-tight connection with outlets. After stretching, they return to a tight, tangle-free coil.

Sure-Grip Locking Electronic
Equipment Power Cords

Create a secure, vibration-resistant connection on both ends—these cords have a hospital-grade plug and a locking connector on the socket.

Sure-Grip Locking Electronic
Equipment Cord Splitters

Create secure, vibration-resistant connections on both ends—these cord splitters have a hospital-grade plug and locking sockets.

Light Duty Power Cords

Designed for indoor applications, these cords are often used to power appliances.

Electronic Equipment Turn-Lock Power Cords

Plug these cords into computers, lab equipment, and office machines that have IEC connections.

M29 Power Cords

Often used in automation systems such as conveyors and sorters, these cords have plug and socket ends, so they quickly connect and disconnect for maintenance and do not need to be hardwired.

GFCI Extension Cords

Keep personnel safe from electric shock with these cords.

Electronic Equipment Outlet Strips

Power computers, lab equipment, and office machines that have IEC connections.

Interference-Limiting Electronic
Equipment Outlet Strips

A filter through the middle isolates two pairs of outlets, so high voltage equipment plugged into one pair won’t affect the other pair.

Recessed Bench-Top Outlet Strips

Power devices above and below your workbench while keeping your outlet strip out of the way.

USB Cords

Connect devices such as computers, printers, and mobile devices.
