Self-Locking Connectors- The Ultimate FAQ Guide

If you are dealing with an excess number of connectors or want to apply connectors in applications that need mating in minimum time, you are in the right place!

INTE-AUTO provides you with Self-Locking Connectors that quickly lock and unlock in a precise time and are also cost-effective.

If you want to learn more about INTE-AUTO Self-Locking Connectors, you could read the FAQ guide article below:

INTE-AUTO Self-Locking Connector is a small bridge between two devices that takes responsibility for data, current, signals or fluid transmission from one device to the other.

It consists of two main external parts called a socket and a plug.

The device or cable where you need to send data, signals or current is connected to the socket.

The plug is connected with the device or cable from where you need to receive data or current for transmission.

The term ‘’self-locking’’ in INTE-AUTO Self-Locking Connectors clearly means that you do not need to apply much effort and time to lock and unlock these connectors.

It is because there is a strong self-latching mechanism installed in the plug and socket in order to complete the locking and unlocking process.

Nowadays, this mechanism is in great demand for all applications where connectors are used for data and current transmission.

You can get straight or elbow configurations of these connectors with a facility of solder, PCB or crimp contacts.

Figure 1 INTE-AUTO Self-Locking Connectors


INTE-AUTO Self-Locking Connectors follow a simple rule for mating and un-mating.

The mating and un-mating totally depend on the self-latching mechanism installed into these connectors.

When you need to mate the plug and socket, you need to push the plug into the socket such that all the plug contacts enter into the socket holes.

During mating, the following process occurs:

  • The self-latching mechanism consists of two half arrowhead shape latches inside the connector’s plug.
  • When you push the plug into the socket, the latches inside the plug retract with the outer shell walls.
  • There is a space inside the socket similar to the shape of the plug’s half arrowhead latches.
  • When the plug’s latches reach that socket half arrowhead shape space, the arrowheads quickly lock or fit into that space.
  • The plug and socket are now strongly mated, and your data, current, signals or fluid can be easily transferred from one device to the other.
  • To un-mate the connection, the outer shell of the plug should be pushed in the backward direction.
  • Doing this will release the plug’s half arrowhead shape latches from the socket grooves, and the plug can then easily be removed from the socket.

Figure 2 Mating Mechanism of INTE-AUTO Self-Locking Connectors

Figure 2 INTE-AUTO Self-Locking Connector’s Mating Mechanism

Yes, INTE-AUTO Self-Locking Connectors can easily and strongly defend accidental cable tugs.

The self-latching mechanism in these connectors does not allow the plug and socket to disconnect even in harsh conditions.

You can only break the connection if you push back the outer shell of the plug.

INTE-AUTO manufactures different types of Self-Locking Connectors that give you different ingress protection ratings.

All the types are strong enough to be used in various challenging situations.

INTE-AUTO Self-Locking Connectors are available in IP50, IP66, IP67 and IP68 ratings.

It is up to you what type of Self-Locking Connector is needed to fulfill your data, current or signals transmission.

Yes, you can easily and quickly fit a bend relief with INTE-AUTO Male Self-Locking Connectors.

Although INTE-AUTO manufactures both types of Male Self-Locking Connectors that have variants or may not have variants.

So, if you want to avoid bending of the cable near the plug, you can order a Self-Locking Connector with a variant.

Figure 5 Variant of INTE-AUTO Self-Locking Connectors

Figure 5 INTE-AUTO Self-Locking Connector’s Variant

INTE-AUTO Self-Locking Connectors are precisely manufactured to perform their duties in almost any environment and tough situation.

Excellent quality brass is used to manufacture the pin contacts of these connectors.

After manufacturing, the brass contacts are then plated with a layer of gold to increase your connector’s life.

If you buy INTE-AUTO Self-Locking Connectors, you can mate a single piece more than 5000 to 6000 times.

Figure 6 Mating Capacity of INTE-AUTO Self-Locking Connectors

Figure 6 INTE-AUTO Self-Locking Connectors Mating Capacity

Sometimes you are in a challenging situation where:

  • You are not able to see the socket


  • You are dealing with many connections that require perfect mating of the plug with the correct socket.

In such situations, you need a system that automatically allows mating only between the correct plug and socket, i.e., the connector allows you blind mating.

INTE-AUTO has made a keying system on their Self-Locking Connectors to achieve this goal.

The keying system consists of one protrude (keying system), or two protrudes (keying system) on the outer surface of the connector’s plug.

These protrude (keying systems) make an angle with the center of the plug such that the angle is equivalent to the space between them.

The protrudes (keying systems) with less angle have less space between them than the protrude (keying systems) having a greater angle.

They have given keying codes represented by codes G, A, B, C, D, E, F, J, K and L.

The code G is standard, having key=1 and 0 degree angle with the plug’s center.

The angle or space between other keying codes is given below:

  • Code A has 30 degrees angle and is represented by α
  • Code B has 45 degrees angle and is represented by α
  • Code C has 60 degrees angle and is represented by α

For INTE-AUTO F Series Self-Locking Connectors, a half-shell shape keying system is designed that contains one or two half-shells as protrudes with codes 1, 2 and 3.

Sometimes there is a need to transfer data, signals or current in an area where the temperature is exceptionally high.

In such areas, a low-quality manufactured connector can never perform well and can never provide you with precise measurements and results.

You can get benefits from INTE-AUTO Self-Locking Connectors in high-temperature environments.

They not only transfer your data, current and signals in an efficient way but also provide you with excellent results flawlessly.

INTE-AUTO Self-Locking Connectors can work at a maximum temperature of about +250 degrees Celsius.

Figure 10 Working Temperature Range for INTE-AUTO Self-Locking Connectors

Figure 10 Self-Locking Connector Working Temperature Range

The military operations are very tough, and they have to perform their duties in all types of hot, cold, soft and harsh environments.

To work in such critical situations, they use the latest technology machines and vehicles that require the quick transfer of data, current, signals, and fluids flawlessly and efficiently.

INTE-AUTO Self-Locking Connectors provide quick and easy connection and disconnection solutions.

In harsh military situations, INTE-AUTO Self-Locking Connectors help them transfer data and current through the latest machines and vehicles faster and more securely.

If you need to transfer data, current, signals or fluid in an environment where high vibrations occur, then INTE-AUTO Self-Locking Connectors is best for you.

The plug and socket of these connectors tightly fit with each other through the self-latching mechanism such that the high vibrations never break the connection nor disturb the flow.

You can implement INTE-AUTO Self-Locking Connectors in applications having 10Hz to 2000Hz vibrations.

These connectors can easily resist this vibration range under IEC 60512-4 test 6d standard.

When current flows through a wire, electromagnetic radiations surround it that can affect the flow of data, signals, or current flowing through another wire near it.

360 degrees screening or 360 degrees EMC shielding is used to avoid electromagnetic radiation from the surroundings.

INTE-AUTO Self-Locking Connectors are 360 degrees EMC shielded so that your data, current, signals or fluid are protected against external interferences.
