What is Pin Header
A pin header (or simply header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings.Male pin headers are cost-effective due to their simplicity. The female counterparts are sometimes known as female headers (also as pin sockets), though there are numerous naming variations of male and female connectors.
Pin Header Connectors
Pin header connectors comprise several different means of connection. Generally, one side is a series of pins which are soldered to a PCB, and they can either be at a right-angle to the PCB surface (usually called "straight") or parallel to the board's surface (confusingly referred to as "right-angle" pins). Such connectors come in a variety of pitches, and may have any number of individual rows of pins.
Headers are a simple connector that can be used in a wide variety of applications, from industrial to consumer electronics. Pin headers consist of one or multiple rows of metal pins aligned into a molded plastic base. Pin headers come in a vast selection of options related to the number of pins or rows, pitch, height, and mounting orientation. Pin headers offer inexpensive, reliable, robust solutions to effectively connect one PCB to another. Pin headers are known as the male side of this connector solution. Their corresponding counterpart is known as the female header.
According to the standard classification of pin connectors in the electronics industry:
According to the spacing, it can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm, and 0.8mm. Depending on the number of rows, there are single row needles, double row needles, triple row needles, etc; According to the packaging rules, there are SMT (horizontal/vertical mounting), DIP (direct insertion/bending insertion), etc; Divided by installation method: 180 ° indicated by S, 90 ° indicated by W, SMT indicated by T table
Industrial Control And Automation
Pin header used in industrial automation systems connect:
● Inputs and outputs to/from PLCs and controllers.
● HMIs and their integrated touch panels.
● System components like drives, power supplies, safety controls, sensors, etc.
● External circuits for power, controls, management, etc.
Removable connections aid troubleshooting and replacement of components in automation systems.
Smart Home Devices
Even in smart home devices and appliances, you will see headers used for:
● Connecting integrated touchscreen panels.
● Linking components like control boards, sensors, Wi-Fi modules.
● Providing serviceability access to internal electronics.
● Power and data ingress/egress.
Header pin usage spans the spectrum from complex industrial equipment down to consumer smart home tech.
3 Tips To Consider When Ordering Pin Header For Your Assembly
1. Identify a Supplier Who Can Achieve Your Desired Custom Pin Design
Before placing an order, you will need to have your design concept ready. Custom pin header achieve different connection purposes. You can sketch your idea on paper or 2D or 3D CAD for more accurate visualization for final customization.
The main questions to ask yourself when it comes to designing a custom pin from scratch are:
Are You Customizing An Entire New Design Or Part Of An Existing Pin Design?
As mentioned earlier, there are several custom pin designs already. However, when customizing a custom pin, you probably have a unique connection need that the existing contact pin header aren't meeting, either in part or as a whole.
Define the need for a custom pin and the specifications you'll require for the new prototype. This initial consideration is crucial as it helps you and your supplier to explore the best practical ways and methods you can adopt to create the custom pin in design and cost.
What Materials Will It Take To Create The Custom Pin?
The material a contact pin comes in plays a paramount role in its connectivity to other machine parts, service applicability, and final production cost. These materials include those that create the base metal of the pin and any plating you may want on your custom design.
Consider the different properties of different materials and the various ways in which these materials work together to be more effective and applicable for the part of the machine under development.
2. Know What Your Assembly Requires in Terms of Production
Once you have the design ready, the next important consideration is where to get your custom pin header produced. Again, you'll want to share this responsibility with a manufacturer who understands every aspect of your design.
An experienced manufacturer should be able to produce quality custom pins that are devoid of flaws. Choose a manufacturer with systems in place to create custom pins including vision inspection processes to ensure your custom pin header diameter, length, thickness, and other parameters as you envision in your design.
Pin header come in varying sizes and shapes, and tolerances in their dimensions guarantee their geometrical tolerances and applicability are accomplished. Choose a company that understands your design concept and can advise and produce a working custom pin that meets the dimensional needs of your connecting parts or machines.
The method by which your custom pin is produced bears a lot of weight on supply and the final cost of production. Depending on the intricacy of your design, you can opt for either of these production methods:
Swaging
The swaging method is best known for producing accurate and efficient custom designs with minimal to zero material losses during manufacturing. This method uses a metal, cold-forming, swaging press and die to progressively form a solid wire or strip of metal into a custom pin design.
Stamping
The stamping method involves using a stamping press and progressive die to shape metal into the desired design. Stamping involves more physical actions on the metal than swaging to achieve the desired. These actions or processes include blanking or punching the metal to for shaping and creating flanges where necessary, embossing, blanking, and coining the metal to achieve dimensional accuracy.
Screw Machining/Turning
The screw machining/turning method involves feeding metal rods through a turning press producing loose piece interconnect pins and contacts. This process creates a lot of metal scrap which adds cost to this fabrication pin forming option.
The above methods produce quality custom pin header but at different timelines and cost implications. Analyze the best equipped and economically and environmentally suited to build your custom pin design, and prepare your order based on the ability of the manufacturer to create and deliver in a time and cost-conscious manner.
3. Ask Your Manufacturer About any Additional Cost Implications
With a ready design and production processes in mind, the next thing to do is consider the cost implications for producing the custom pins. Manufacturers will quote for you based on the method and materials they use to create your custom pin. A low-cost quote does not necessarily equal quality production, and neither does a high quote.

FBelec Pin connector
Pin, a kind of connector, English Name: pin header.
This connector is widely used in PCB circuit boards in electronics, electrical appliances and instruments. Its function is to act as a bridge between blocked or isolated circuits in the circuit and undertake the task of current or signal transmission. It is usually used together with the busbar to form a plate-to-plate connection; or it is used together with the electronic harness terminal to form a board-to line connection. It can also be used for plate-to-plate connection independently.
Due to different specifications required by different products, there are many types and specifications of pin arrangement, which are classified according to the standard of pin arrangement connector in the electronic industry.
According to the spacing, it can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm and 0.8mm.

The jack structure can prevent misinsertion. 254 / I series square pin section is 0.64 × 0.64mm。 The above two pins adopt blunt edge angle design, which can be applied to the field of high frequency technology. The contact part of pinhole is plated with gold, with corrosion resistance, low contact resistance and high reliability.
Pin header / male pin header
Row pins are generally widely used in the connection of PCB boards, with the reputation of universal connector. Generally, they are paired with connectors such as bus bar, wire end, etc. With the competition in the pin connector market, some manufacturers start with electroplating (imitation gold) and materials (green clad steel, alloy, etc.) to reduce costs, but also reduce the service characteristics and service life of products.Header Connector socket.
