About NEMA Plugs, Sockets, and Receptacles

Plug (Front)

Socket × Socket (Back)

5 Pole Plug × 5 Pole Socket × 5 Pole Socket

To save space and reduce the number of cords in industrial automation setups, these splitters join two devices with M12 connectors to a single cord, distribution block, or I/O module with M12 connectors. Often used with sensors and switches, they send or receive two signals through one connection. They’re rated IP67 to stand up to dust and brief submersion.

For the straight female socket connection, the 2nd pole is a contactless pole.

M12 Plug

M8 Socket × M8 Socket

4 Pole × 3 Pole × 3 Pole

Join two devices with M8 connectors to a single cord, distribution block, or I/O module with M12 connectors to save space and reduce the number of cords in industrial automation setups. Often used with sensors and switches, these splitters send or receive two signals through one connection. Rated IP65 and IP67, they’ll stand up to dust, low-pressure washdowns, and brief submersion.

Note: M12 plugs have an extra pin on the face that is not used.

Nano M8 Splitters

Plug (Front)

Socket × Socket (Back)

Reduce the number of cords needed to send and receive signals where space is tight. These splitters connect two sensors, switches, and devices to a single cord or port in a distribution block or I/O module.

IP67 rated when connected, they seal out dust and water if briefly submersed.

Mini Splitters

Simplify wiring and reduce the number of cords in your automation setup. These splitters create a branch off a main cord or connect multiple devices with a mini connection to a single port in a junction box or I/O module. A threaded housing securely mates with other mini connectors to keep out contaminants and won’t come loose from shaking or vibration. They have a standard pole layout and housing thread size to reduce the chance you’ll mis-mate connectors.

When mated, these connectors meet IP68 and NEMA 6P for protection against dust, submersion, washdowns, and weather.

Caps protect connectors and maintain their IP and NEMA ratings when not in use.

Thread adapters connect plugs and sockets that both have internal threads.

Washdown Straight-Blade Connectors and Cords

All connectors have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. When mated, connectors meet NEMA 6P, NEMA 12, and either IP67 or IP69K.

Connectors that meet IP67 resist temporary submersion.

Plugs mate with female receptacles and female sockets with an attached cover.

Cord splitters power multiple devices from a single outlet.

Note: The current rating of your plug should not exceed that of your socket or receptacle.

Washdown Turn-Lock Connectors and Cords

When mated, connectors meet NEMA 6P for protection against corrosion and washdowns. All have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Plugs mate with female receptacles and female sockets with an attached cover.

Cord splitters power multiple devices from a single outlet.
