Electrical Wiring and Connecting

USB Adapters

Transmit data between computers, connect two like cables, or connect devices that have different USB sizes or styles.

USB Hubs

Connect additional USB ports to your computer.

Insulated Wire Ferrules

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated Wire Ferrules

Add strength and stability to stranded wire to protect it from damage and speed insertion into terminal blocks.

Insulated Pin Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated Pin Terminals

These solid pins make it easier to insert stranded wire into screw-clamp connections.

Wire Ferrule Assortments

Keep a variety of ferrule sizes on hand.

Cords for Development Boards

Make quick, secure connections between your development board and your system’s components, such as sensors and actuators.

Washdown USB Cords

Rated IP67, these cords withstand washdowns and temporary submersion. Connect them to a USB device inside an enclosure.

Caps for Washdown USB Cords

Attach these caps to the socket end of washdown USB cords to maintain an IP67 rating when cords are not in use.

Nano M8/USB Adapter Cords

These cords have a Nano M8 connector (also known as a pico connector) on one end and an USB Type-A connector on the other.

Robot-Ready Electric Vacuum Lifters

Connect these lifters to your robot arm to pick up and move items using suction. They're electric, so you don't need a compressed air source.

Temperature and Humidity Monitoring

Thermocouple Connectors

Add these connectors to thermocouple wire for easy attachment to thermometers and control panels.

Panel-Mount Thermocouple Connection Strips

Connect multiple thermocouple probes to an instrument panel.

Panel-Mount Thermocouple Connectors

Plug thermocouple probes into a control panel.

Thermocouple Adapters

Convert round-pin male connectors to flat-pin male connectors.

Threaded Thermocouple Connectors

Also known as feedthrough connectors, these mount through threaded tank openings to make connections between thermocouple probes and external equipment.
