Electrical Connectors

Micro M12 Screw-Together Connectors

Because they tightly thread to M12 connections, these connectors won’t let contaminants in or come loose from vibration in rugged industrial environments and automated systems as they send power and signal or just power to your equipment.

Harsh Environment Micro M12
Screw-Together Connectors

Send power and signal to devices with M12 connections that are exposed to some of the toughest industrial stresses—from welding to metal machining and changing temperatures.

Mini Connectors

Often used to send power and signal to automated systems, motors, and pumps, these mini connectors carry higher currents than M5, M8, and M12 connectors.

Harsh Environment Mini Connectors

Send higher current than M5, M8, and M12 connectors near tough industrial jobs, such as welding and metal machining.

Shielded Mini Connectors

Protect against signal interference while sending 2-3 times more current than M12 connectors.

Mini Splitters

Simplify wiring and reduce the number of cords in your automation setup.

Build-Your-Own Molex Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. Use them with standard Molex connectors.

Molex Compact Connector Sets

Sets include a plug and socket with wire leads already installed, so they can be quickly added to existing wiring systems. They fit standard Molex plugs and sockets.

Weatherproof Molex Compact Connector Sets

A sealed housing protects connectors from weather. Sets include a plug and socket with wire leads already installed. They fit standard Molex connectors.

Build-Your-Own AMP Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. They fit AMP MATE-N-LOK connectors.

AMP Compact Connector Sets

Connectors come assembled with wire leads already installed, so they can be quickly added to existing wiring systems. Use them with AMP MATE-N-LOK connectors.

Stackable Connectors

Stack as many connectors on top of each other as needed—the housings clamp together to form a secure attachment.

Mil. Spec. Screw-Together Connectors

Rated to MIL-DTL-5015 specifications, these connectors are compatible with other products that meet the same standard. They screw together for a secure connection.

Multipurpose Build-Your-Own Latching Connectors

Assemble a connector that can handle multiple applications at once. Combine inserts that send power, signal, and data with a base and a hood.

Solenoid Valve Connectors

Power hydraulic and air-powered valves, motors, pumps, and pressure switches.

Deutsch-Style DC Connectors

Use these connectors in vehicles and other agricultural and construction equipment.

Panel-Mount Deutsch-Style DC Connectors

Install these connectors in panels, enclosures, and bulkheads to join equipment with compatible Deutsch-style DC connectors.

Build-Your-Own Weatherproof DC Connectors

Configure a connector for your application by combining housings with pins and sleeves for different wire sizes. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Weatherproof DC Connector Sets

Each set includes one plug and one socket. These connectors withstand moisture, harsh engine fluids, and high temperatures. Also known as weather-pack connectors.

Ready-to-Use Weatherproof DC Connectors

Quickly replace or add connectors to an existing wiring system—connectors come assembled with wire leads already installed. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Barrel-Style DC Connectors

Made with industry standard barrel-style ends, these connectors carry DC power between electronic devices and power supplies.

Build-Your-Own Molex Circuit
Board Connectors with Locking Tab

Connect wires to circuit boards with Molex Mini-Fit push-in connectors. A locking tab holds the housing and plug together once they’re mated.

Build-Your-Own Molex Circuit Board Connectors

Connect wires to your circuit board with these Molex KK push-in connectors.

Build-Your-Own Amphenol Circuit Board Connectors

Attach wires to your circuit board with these Amphenol PV connectors.

Circuit Board Barrel-Style DC Connectors

Install these connectors directly onto circuit boards to carry DC power from a power supply to your device. The industry standard barrel-style ends, which are often found on power supplies for laptops, wireless routers, and other common electronics.

IEC Safe-Break Pin-and-Sleeve Connectors

These connectors meet international standards IEC 309-1 and 309-2. They prevent an electrical arc when separating mated connectors, so you can safely connect and disconnect with the power on.

Chemical-Resistant Connectors

With a PVC housing, connectors withstand exposure to chemicals, oil, fuel, and salt water.

Flat Pin-and-Sleeve Connectors

Reduce the likelihood of slips and falls in high-traffic areas—connectors won't roll when stepped on.

Audio Equipment Connectors

These connectors are designed for use in audio equipment.

Circuit Board Audio Equipment Connectors

Add a spot on your circuit board for plugging in headphones and other audio equipment.

Slip Rings

Maintain an electrical link between a moving part and a stationary part.These rings are typically used on rotating jib cranes, rotating signs, and test equipment.

Power Cords

Micro M12 Cords

The threaded ends on these cords seal out contaminants and resist coming loose from vibration in tough industrial environments and automated systems while sending power and signal to devices with M12 connections.

Harsh Environment Micro M12 Cords

TPE insulation protects these cords from some of the toughest industrial conditions, including abrasion, coolants, chemicals, UV rays, and weld slag. Use them in areas with welding, machining, and fluctuating temperatures to send signal and power to M12 proximity switches, valves, and other devices.

Mini Cords

With a higher maximum current than nano M8 and micro M12 cords, these mini cords are often used with automated systems, motors, and pumps.

Harsh Environment Mini Cords

Often used for automated systems, motors, and pumps in tough industrial areas such as near welding and metal machining, these cords carry higher current than M5, M8, and M12 cords.

Milwaukee Tool Power Cords

These cords work with any Milwaukee tool with a pin socket (Quik-Lok) connection.

Solenoid Valve Cords

Use these cords with hydraulic and air-powered valves, motors, pumps, and pressure switches. They have a solenoid valve socket on one end and an M12 threaded plug on the other.

Deutsch-Style Power Cords

Use these cords in vehicles and other agricultural and construction equipment.
