Multipurpose Build-Your-Own Latching Connectors

Combine power, USB, computer, and compressed air inserts to build a connector that sends signal, power, and data. A complete connector requires a hood, a base, two frames, and a male and female insert for each slot in the frame. The frames fit into the hood and base, and the inserts snap into the frame. Select components based on the number of slots needed. Once assembled, connectors are rated NEMA 4X, 12, and IP65 for protection against dirt, washdowns, and oil/coolant dripping.

Crimpers (sold separately) are required for wire installation for crimp-on connectors. They ratchet to ensure the correct pressure is applied to every crimp.

Extraction tools (sold separately) make it easier to remove pins or sleeves from 17- and 20-pole power inserts.

High-Current Compact Latching Connectors

Carry up to four times the current of standard compact latching signal/power connectors. To protect connections while maintaining access, the base and hood latch together securely, yet can be quickly detached for equipment repair or replacement. They’re rated IP65 for protection against dirt and water projected from a nozzle.

Mil. Spec. Compatible Connectors

Connectors secure with a quarter turn when mated, yet unlock and pull apart with minimal force. All have the same pin and socket configurations as MIL-DTL-26482, so they are compatible with other products that meet the same standard. They’re rated IP67 to protect against dust and temporary submersion. When mating connectors, the gender and housing lock location must be opposite. Poles are labeled with letters on the face of the connectors to ensure proper connection.

Crimpers (sold separately) are required for wire installation.

Chemical-Resistant Connectors

Three Pole

With a PVC housing, connectors withstand exposure to chemicals, oil, fuel, and salt water. Each set includes one plug and one socket. They’re often used in construction vehicles and machine tool applications. All come assembled with wire leads already installed so they can be quickly added to existing wiring systems. When mated, connectors meet IP67 for protection against dust and temporary submersion.

Vibration-Resistant High-Current Connectors

Make secure connections with machine tools, robots, and other equipment that vibrates frequently and carries currents as high as 300 amps. A wave spring holds these connectors firmly in place when mated, so they won’t come loose. They also evenly distribute force to absorb vibration. To install, push them into a compatible connector and lock with a quarter turn. A click confirms they’re secured. You can pull these connectors out quickly and easily for maintenance.

IP67 rated when connected, all block out dust and can be briefly submerged under water. Their insulation insert meets UL 94 V-0, so it resists catching fire.

Shielded connectors guard against interference from nearby equipment.
