Electrical Connectors

IEC Pin-and-Sleeve Connectors

Meet international standards IEC 309-1 and 309-2.

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.

Safe-Break Pin-and-Sleeve Connectors

Connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc.

Caps for Safe-Break Pin-and-Sleeve Connectors

Caps are watertight to protect safe-break plugs when not in use.

Hazardous Location Safe-Break
Pin-and-Sleeve Connectors

Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They also prevent an electrical arc when separating mated connectors so you can safetly connect and disconnect with the power on.

Caps for Hazardous Location
Safe-Break Pin-and-Sleeve Connectors

Caps are watertight to protect hazardous location safe-break plugs when not in use.

Corrosion-Resistant Pin-and-Sleeve Connectors

When used together, connectors maintain a watertight and corrosion-resistant NEMA 4X connection.

High-Current Pin-and-Sleeve Connectors

A current rating up to 400 amps makes these connectors suitable for use in industrial machinery and floodlights.

Caps for High-Current Pin-and-Sleeve Connectors

Protect high-current connectors when not in use.

Stackable Pin-to-Pin Connectors

Also known as power-pole connectors, these single-pole connectors join two pin connections, rather than a pin and socket. They stack from the top and sides to form any configuration.

Flat Pin-and-Sleeve Connectors

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