Instead of their excellent performance in medical applications, INTE-AUTO Plastic Connectors also apply in many other fields. With the help of this FAQ guide article, you can get complete knowledge about the INTE-AUTO Plastic Connectors.

The INTE-AUTO Plastic Connector is an excellent solution to transfer data, current, and signals with maximum accuracy and precision from one place to the other.

It consists of two main parts named plug and receptacle.

They are designed with an excellent push pull self-latching mechanism for strong and easy locking and unlocking to avoid accidental disconnects in an efficient manner.

In order to avoid mismatch of different Plastic Connector’s plug and receptacle, INTE-AUTO has designed a coding system or keying system on them.

You can get INTE-AUTO Plastic Connectors of various sizes and contacts that are gold plated with copper to ensure maximum mating cycles.Figure-1-INTE-AUTO-Plastic-Connector

Figure 1 INTE-AUTO Plastic Connector


The INTE-AUTO Plastic Connectors have been manufactured by using excellent quality components whose details are given below:

  • The insulator of the plug and receptacle has been manufactured using Polyphenylene Sulfide (PPS) material that is high-temperature and chemical resistant.
  • The contacts are manufactured using brass plated with gold to ensure thousands of mating cycles.
  • All other components that include an outer shell, collet nut, collet, etc., are manufactured using Polycarbonate (PC) that have low density and provide you with chemical and high-temperature resistance.

Polyphenylene Sulfide (PPS) and Polycarbonate (PC) material have passed the UL certificate that ensures that all connector’s parts are manufactured correctly for higher safety and are eligible for use in the medical industries.

 Figure 2 Plastic Connector’s Components

In order to correctly align the Plastic Connector’s plug and receptacle before connection, INTE-AUTO has designed a unique keying system.

The connector’s plug consists of one or two protrudes (keying system) with key codes named G, A, B, C, H, and J.

For one protrude (keying system), the keying system is called a standard G key with a 0 degree from the center of the plug.

The other key codes have assigned different angles, i.e., the two protrudes (keying system) are spaced apart from different angles, which are measured from the center of the plug.

  • Key code A is 40 degree
  • Key code B is 60 degree
  • Key code C is 80 degree
  • Key code H is 170 degree
  • Key code J is 155 degree

The receptacle also consists of a profile groove like the protrudes (keying system) on the plug that allows the protrudes to insert into them during mating.

Figure 5 Bend Relief and Collet Nut with Different Colors


You can easily assemble the INTE-AUTO Plastic Connectors by following the steps described below:
  • Cut the outer rubber covering of the cable from its end about 0.5 inches and expose its small inner wires.
  • Cut the outer layer of these small wires and expose the inner conductor that the cable uses for transferring data, current, or signals.
  • Pass the cable end from a bend relief, collet nut, and then from the collet.
  • You have to carefully solder the inner conductor of the wires with the insulator contacts.
  • After that, the collet should be put onto the insulator such that the collet’s lug accurately mounts on the insulator’s slot.
  • Now after aligning the collet and insulator, insert them gently inside the outer shell of the plug until they cannot get further inside it.
  • You should now screw the collet nut on the back of the collet and use bend relief at this stage.
  • The Plastic Connector’s plug is then ready to be mated with the receptacle.
  • You should solder the fixed receptacle with the circuit or free receptacle with the cable where you want to send the data, current, or signals.

Plastic Connector's Working Temperature Range

Figure 10 INTE-AUTO Plastic Connector’s Temperature Range

Determine the diameter of the plastic connector and the specifications of the wire. Choose the outer diameter of the wire or cable and the joining requirements with the shell, volume, weight, and if you need to connect to a metal tube or not.

Installation method and shape: After determining the installation size and specifications, identify if you need straight or elbow pins.

Electrical parameter requirements: Connectors are electromechanical accessory that connects electrical circuits together. So, your choice should be based on the electrical parameters of the circuits.

Rated voltage: Connectors should be able to withstand a range of voltages based on the environments they will be used in. Safety requirements and different maximum working voltages should also be considered.

Rated current: To limit the rated current, the temperature rise inside the connector should not exceed the specified rating. Consider this especially for multi-core connectors because individual contacts are derated as current increases.

Aesthetics: The electrical connectors should also look good on a panel. Consider aesthetic design, shape, and color.

Performance: consider IP rating, operating temperature range, mating cycles, and such.

The number of circular push-pull self-locking connectors on the market is growing. Prices quoted by suppliers can be either high or low depending on quality. Customers are confused on which to choose.

So what causes the price difference? Based on our years of experience in the industry, the major factors that affect the price of connectors are:

1. The material of the plastic connector:

The INTE-AUTO circular push-pull self-locking plastic connector shell and inner parts are made of PC (polycarbonate). The insulator generally uses PPS (absolutely no second-hand material).

2. The plating thickness of the push-pull self-locking plastic connector:

To extend connector life, the insulator pins assembly of each push-pull self-locking connector is gold-plated. Gold plating is waterproof, prevents rust, prevents corrosion, and improves conductivity.

The price will vary depending on the thickness of the gold plating. The thicker it is, the higher the cost—1u (mark) gold is the cheapest gold plating layer thickness.

The pins of the INTE-AUTO push-pull self-locking connectors are all plated with thick gold above 8u. This guarantees high quality and durability.

3. The precision of the push pull self-locking plastic connector:

Prices will also depend on contact designs. These designs have specific purposes and will need different assembly methods.

For example, the smallest size 0P series connector in the P series connector is generally more expensive than the 1P series with the same number of pins. This is because the assembly of the connector is done manually.

Assembling the small plastic connector is harder than assembling the larger one. The small connector cannot be assembled faster by hand, so the price is higher.

For example, the P Series connector with many key pin positions will be more complex and more expensive.

4. The type of equipment used to manufacture 

Like many circular push-pull self-locking connectors, the price of automatic lathe processing is much lower than that of core machine processing. This is because the production process of the automatic lathe is not as sophisticated as the core machines’.

5. The number of connectors required

When a customer asks about the price of a plastic connector, the manufacturer will usually estimate the price and delivery date based on the quantity ordered, the specifications required, and the stock availability in the warehouse. If the product demand is small, the cost will increase accordingly. Manufacturers usually give preferential treatment for large order quantities.

Faster service: As a supplier, INTE-AUTO works hard to bring you timely service.

Better cost-efficiency: INTE-AUTO understands the need for continuous cost improvement to reduce your total spending.

Faster delivery time: INTE-AUTO understands that a shorter lead time gives you an advantage in the industry.
