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.

Shielded Micro M12 Screw-Together Connectors

Block signal interference from nearby devices, such as motors and transmitters, while maintaining a strong, stable connection for M12 threads.

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.

Push-In Miniaturized Connectors

Push these connectors together to quickly create signal and data connections in tight spaces. They need less space to mate than screw-together connectors, which require two hands to twist them in place.

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.

Mil. Spec. Compatible Connectors

These connectors have the same pin and socket configuration as connectors that meet MIL-DTL-26482, so they can be used with products that meet the same standard. Quickly mate them by pushing them together.

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.

Compact Latching Connectors

The smallest latching connectors we offer, these fit in tight spaces. The base and hood latch together securely, yet can be quickly detached for equipment repair or replacement.

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.

Servomotor M23 Connectors

These general purpose M23 connectors send power or signal to servomotors, servocontrollers, and servodrives.

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.

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.

Sensor 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.

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.
