1.27mm Pitch Pin Headers

Applications of 1.27mm Pitch Pin Headers

Small equipment and devices can highly benefit from the small but robust stature of the 1.27mm pitch pin header as its material is tested for high-vibration and shock requirements of the automotive, industrial, and consumer electronics industries. This 1.27mm pitch pin header is widely used in diverse applications such as:

• Medical Diagnostic and Monitoring equipment
• Communications: Telecoms and Datacoms
• Industrial and Automotive Control and Test
• Retail and Point-Of-Sale equipment
• Mil/Aero and Home Security
• Solar applications
• Weighing systems
• Vehicle infotainment
• Computer peripherals
• Telecommunications
• Heart monitors

Mount Type: Through-hole vs Surface Mount

1.27mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).

Through-Hole (Poke-In)

• Best used for high-reliability products that require stronger connections between layers.
• Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
• Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
• 1.27mm vertical single row header, 1.27mm vertical dual row header, 1.27mm Elevated single row pin header, 1.27mm Elevated dual row pin Header, 1.27mm Right-angle single row header and 1.27mm Right-angle dual row header are some
• examples of Scondar products with through-hole mount type.

Surface-Mount

• The most common electronic hardware requirements are SMT.
• Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
• Cost of processing and handling is reduced.
• SMT components can be mounted on both side of the board.
• Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
• 1.27mm Right-angle Dual Row pin header, 1.27mm SMT Single row pin header, 1.27mm SMT Dual row pin header and 1.27mm Elevated Dual Row Pin Header are Scondar’s SMT pin headers.

Soldering Temperature for 1.27mm Pitch Pin Headers

Soldering SMT pin connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.

Pin-Type: Vertical (Straight) and Right-Angle

1.27mm pitch headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle male header. Vertical or Straight Pin (Male) Header Orientation

• One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called “straight” or “vertical”) or..

Right-Angle Pin (Male) Header Orientation

• Parallel to the board’s surface (referred to as “right-angle” pins).

Each of these pin-types have different applications that fit with their specific configuration.

PCB Connector Stacking

Elevated Pin Header Orientation

• Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.

Profile Above PCB

• This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.

Single, Dual or Multiple Number of Rows

For a 1.27mm straight or vertical male pin header, the standard number of rows that Scondar offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-50 pins while for dual row, the number contacts may vary from 4-100 pins.

Pin Material

The pins of the connector have been designed with copper alloy. With customer’s demand the pins can be made gold plated.

Breakaway design

The pin headers are also equipped with a breakaway design making them fully compatible with their female receptacles.

Custom 1.27mm Pitch Pin Headers

Customizable 1.27 mm pitch pin headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed. Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.

Tape and Reel Packaging for SMT Components

Scondar’s SMT headers are offered with customizable mating pin lengths, in which each series has multiple numbers of circuits, summing up to a thousand individual part number combinations per connector series. The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation. Scondar also offers a range of custom Tape and reel carrier strip packaging cavities.
