⚡ Three-step selection

Start With the Connection Job

Use these three checks before comparing individual part numbers.

1

Choose the circuit

Identify power, control, or signal duty. Voltage and current requirements can further narrow down the selection.

2

Count connections

Confirm the required poles plus protective ground. Available configurations range from 2 to 17 poles.

3

Match the environment

Check enclosure space, temperature, vibration, and ingress exposure of your application. Choose from IP54, IP65, or IP67 protection as needed.
