Hinged Fastener Caps

A one-piece hinged design allows frequent access to screw heads without misplacing the top. To conceal and protect the entire screw head, insert your screw through the hole in the base and flip the hinged top over. All of these caps are UV-resistant. The inside height listed is with the two parts snapped together.

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. They can also power devices as they send data, so you don’t need a separate power cord. But, the device must be Power over Ethernet (PoE) compatible. These connectors are often used with EtherNet/IP, Profinet, and EtherCAT systems. Since they’re shielded, they block signal interference from nearby devices, maintaining their speed and data integrity. Poles and keyways on the face adhere to standard coding layouts to reduce the chance you’ll mismatch connections.

When choosing an Ethernet connector, make sure you match or exceed your network’s category industry designation. These connectors are backward compatible—for example, a Category 6 connector will work in a Category 5 network, but it’ll only run at the Category 5 speed.

A-coded and X-coded connectors send data faster than D-coded connectors, so they’re best for robotics and other systems that run multi-step programs.

Adapters create a transition point between an M12 and RJ45 connection. Use them in panels or walls—your tough threaded connection on one side and your control panel and computer or PLC on the other.

IP rated connectors keep out dust and can be used in wet areas when mated or capped. IP65 connectors can be lightly rinsed. IP67 connectors can be submerged temporarily.

Add caps to protect connectors and maintain their IP ratings when not in use.

Panel-Mount USB Adapters

These panel-mount adapters have a female USB connection on both ends to join two USB cables.

Install adapters with a metric mounting thread into a panel cutout with no additional fasteners needed.

Adapters with mounting fasteners included mount to panels of any thickness, as long as you drill a hole first.

Shielded adapters have an inner metal body that reduces interference from nearby equipment and devices.

Caps (sold separately) protect adapters when not in use. They’re tethered, so you can open them in any direction for access from any angle. Caps rated IP67 protect adapters from against washdowns.

Label holders (sold separately) snap onto the front of adapters.

Panel-Mount Ethernet Adapters

Shown with Cap

Mount these adapters in a panel cutout. They have an RJ45 female connection on both ends to join two Ethernet cords.

Shielded adapters protect equipment from electromagnetic interference. Those that screw in don’t require additional drilled holes or fasteners to mount. They need a more precise panel cutout than adapters that screw on.

Add a cap to protect these adapters when not in use. Hinged caps open and shut quickly at a fixed angle, so they’re more convenient for frequent access than tethered caps. Tethered caps can open in any direction, letting you access adapters from any angle. IP40-rated caps have a locking mechanism for extra security.

Label holders (sold separately) snap onto the front of adapters.

Shown with Label and Label Holder

No drilling or fasteners needed—a screw-in cover plate makes it easy to mount these chargers for powering up phones, tablets, speakers, cameras, and other small devices. They have push-in terminals to quickly connect both solid and stranded wire.

To wire these chargers, press down on their internal clamp with a screwdriver or other narrow tool. Push your wire into the terminal, then remove the screwdriver.

Add an optional cap to protect these chargers when not in use.

Label holders (sold separately) snap onto the front of the chargers.

Panel-Mount USB Cords

With a flange on the socket end, you can mount these cords in a panel cutout to move data between computers, printers, and mobile devices. Backward compatible, all work with cords and connectors that meet the same or lower USB standard.

Shielded and double-shielded cords have insulation that reduces interference from nearby equipment and devices.

Cords with an external housing thread screw into your panel and don’t require fasteners. Because they mount nearly flush with your panel, they protect the connector from damage and won’t snag on equipment and other cords.

Add a cap to protect the end mounted in a panel when it’s not in use. Hinged caps open and shut quickly at a fixed angle, so they’re more convenient for frequent access than tethered caps. Tethered caps can open in any direction, letting you access adapters from any angle. IP40-rated caps have a locking mechanism for extra security.

Label holders snap onto the end mounted in a panel.
