High-Current Latching Connectors
Able to carry more than twice the current of standard latching signal/power connectors, these can be used with thermosensors or brakes on large motors. Use them 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 NEMA 4X, 12, and IP65 for protection against corrosion, washdowns, dirt, oil/coolant dripping, and water projected from a nozzle.
4-pole connector has two control pins to prevent arcing if it is disconnected before the power is turned off.

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.

High-Current Pin-and-Sleeve Connectors
A high current rating makes these connectors suitable for use in industrial machinery and floodlights. Current rating is based on using these connectors with the largest size 194° F rated cable in the wire size range given; current ratings decrease as the cable size decreases. The housing is shatter- and crack-resistant rubber so they can withstand rough environments. Push and twist to join plugs and sockets. When mated, they form a vibration-resistant connection to prevent accidental disconnection. Rated NEMA 3R, they protect against falling liquids and light splashing.
Adapters (sold separately) allow you to change the connector’s gender and make multiple connections from a single power source.
Caps (sold separately) protect connectors when not in use.

High-Current Pin-and-Sleeve Cords
Send power from generators to keep the lights on and equipment running. These cords are often used to convey temporary power during outages or at trade shows and mobile job sites. Able to send currents above 250A, they’re commonly connected to power distribution panels and transfer switches. Push and twist to lock them in place, where they remain secure against high current loads, vibration, and pulling. They don’t require tools to connect or disconnect, making them convenient for short-term setups.
For outdoor use, these cords are rated NEMA 3R for protection from rain, snow, and sleet. They also resist sunlight, oil, and chemicals.
