Manufacturing and Technical Details


Most frequent questions and answers

You are always required to connect two devices or cables in order to transfer signals, currents or data.

INTE-AUTO F Series Core Connectors are used to fulfill this requirement.

They act as a small bridge between two cables or devices that can allow the transmission of current, signals and data among them in an efficient manner.

These connectors are available in metallic versions with two main external components:

  1. Plug
  2. Receptacle

The receptacle is connected to the cable, device or panel where you want to transfer your data, signals and current.

The device or cable from where you get your data, signals and current is always connected with the plug.

You have to connect the plug with the receptacle to start the transmission process.

INTE-AUTO Core Connectors have a simple mating and un-mating mechanism due to having a strong and reliable push-pull self-latching mechanism.

Its contacts are gold-plated to get maximum mating cycles.

These connectors are available in both straight and elbow configurations with different sizes and pin connections.

INTE-AUTO Core Connector’s mating and un-mating is a very simple and quick process.

You do not need much time and effort in order to mate and un-mate these connectors.

These connectors have a reliable and super strong self-latching mechanism that provides you with non-breakable connections even in harsh and challenging situations.

In the self-latching mechanism, arrowhead shape latches are fitted in the plug and receptacle.

The connector’s receptacle is consisted of an arrowhead shape groove inside its housing to fit the arrowhead shape latches of the plug.

The mating and un-mating can be completed by the following process:

  • First of all, you must align the half-shell key of the plug and receptacle
  • After alignment, you should push the connector’s plug into the receptacle
  • In other words, you must push the plug until you hear an audible click sound from the receptacle.

In this way, you will get a strong connection between INTE-AUTO Core Connector’s plug and receptacle that can only break by the steps below:

  • To unlock the connector, simply make a backward force on the connector’s plug
  • Doing this will remove the plug’s latches from the connector’s arrowhead groove
  • After this, the plug can easily be removed from the receptacle, and the connecter will then be unlocked.
