Are Connectors Really Important?

How often have you heard something like: "Oh, no problem, we'll just add a connector." Just adding a connector may sound like a simple solution, but there are a multitude of things to consider when selecting the correct connector. Some may be obvious, like the number of contacts, wire size or the NEMA/IP rating. Other things often get overlooked. Things like the ease of use, both in the installation and in the everyday operation of the machine. Quite often people overlook durability and find themselves redesigning systems after a number of broken connections occur in the field. Connections can fail due to vibration, frequency of use, or just using delicate connections for harsh applications. The next time you need a connector, ask yourself some of the questions below.

  1. Will the connection be made in the field, or in a controlled environment with testing prior to shipment?

  2. Are special tools required for installation? If so, does the installer have them? How expensive are they and how many installers will need them?

  3. Does the system experience vibration?

  4. Will the connector be unplugged and reconnected after installation? If so, how frequently?

  5. Is the selected connector appropriate for the surrounding environment? That plastic automotive connector may not be appropriate for your rock crushing machine.

  6. Are the connectors hidden in the system, or exposed in the operators work area where they can be vulnerable to damage?

  7. Can the connector be unplugged when the system power is on? If so...

  8. Should the connector be rated as a disconnect?

  9. Did you remember to design the power to flow from the female or unexposed pins?
