INTE-AUTO SP21 Connectors are the latest technology-based instruments that connect two devices and precisely complete the data and current transmission process.

The plug and socket are two of their major external components having a plastic outer shell.

The wires in the cable are directly soldered with the plug, and a socket is used to mount the device panel.

These contacts are made with brass material and then gold-plated for maximum protection.

SP21 Connectors are the largest SP series connectors such that they can engage a cable having a diameter range between 4.5 mm to 12 mm.

They use an excellent bayonet threaded coupling system in order to tightly mate and un-mate the plug and socket.

Once these connectors are mated, the connection can never break by accidental disconnects until you un-mate the plug and socket.

You can get multipole configurations for INTE-AUTO SP21 Connectors, and they are also available in different sizes and pin connections.

Figure 2 INTE-AUTO SP21 Connector’s Components

INTE-AUTO SP21 Connectors can be easily applied to various applications due to the strong bayonet threaded coupling system in these connectors.

In order to learn the use process of INTE-AUTO SP21 Connectors, you should follow the steps below:

• First of all, you must disassemble the plug, i.e., you should untighten the front and back locking nut and separate the central part of the plug.
• Now remove the locking nut from the plug contact’s part.
• Cut the cable using a razor and expose small inner wires.
• Now cut the small wires to expose the internal conductor.
• Pass the cable from the back locking nut and then from the plug’s central part.
• Solder the small wire’s conductors with the plug contacts.
• Now again, attach the front locking nut with the plug contact’s part.
• Then tighten the plug contact’s part and front locking nut with the plug’s central part.
• Tight the plug’s back locking nut by rotating it in the clockwise direction.

Now the plug is ready to be mated with the socket.

You should repeat the above steps in order to connect the socket with the cable or device.

• Now insert the plug contacts carefully into the socket holes until they cannot go further.
• At this stage, you should rotate the plug’s front locking nut in the clockwise direction in order to tighten the connection.

Now the connector is ready to transfer data and current.

Yes, it is necessary to use dust caps in INTE-AUTO SP21 Connectors.

The sockets have designed caps in order to achieve waterproof and dust proof facility.

INTE-AUTO SP21 Connectors are already protected from dust particles and water using double silicone rings installed into them.

Dust caps are installed to give extra protection to the connectors when you are not using them.

The dust caps can protect the contacts so that the contacts can have a longer lifetime, they never affect the rate of data and current transmission
