Product Description

Customizable PCB Connector for Board-to-Board and Wire-to-Board Applications

The 1.27 mm / 2.00 mm / 2.54 mm Pitch Female Header, Side Entry Type is a configurable PCB connector designed for applications where the mating direction needs to be horizontal or parallel to the PCB.

Available in three common pitch options—1.27 mm, 2.00 mm and 2.54 mm—the connector can be configured with different pin counts, rows, insulator heights, contact plating and termination dimensions according to the customer's PCB layout and mating requirements.

The side-entry structure is particularly useful when a conventional vertical female header would interfere with enclosure height, PCB stacking, cable routing or adjacent components.

It can be used as a mating receptacle for male pin headers in board-to-board, wire-to-board and internal PCB interconnection applications.

Why Choose This Side Entry Female Header?

1. Three Standard Pitch Options for Different PCB Layouts

The biggest selection advantage is the availability of three widely used pitch configurations:

• 1.27 mm (0.050") – for compact and relatively high-density PCB layouts
• 2.00 mm (0.079") – a compromise between board density and mechanical spacing
• 2.54 mm (0.100") – widely used for conventional PCB interconnection and standard pin-header designs

This allows engineers to select the pitch based on PCB space, mating header, signal density and mechanical clearance, rather than redesigning the connector interface around a fixed pitch.

Commercial female-header product families also commonly define 1.27 mm and 2.54 mm versions with different pin counts and row configurations.

2. Side-Entry Structure for Horizontal PCB Interconnection

Unlike a conventional vertical female header, the side-entry female header changes the mating direction to the side.

This can be useful when the equipment enclosure has limited vertical clearance.

Typical design considerations include:

• PCB stacking;
• Horizontal module insertion;
• Restricted enclosure height;
• Parallel PCB arrangement;
• Cable or harness routing;
• Connection to a perpendicular PCB.

For equipment designers, this means the connector can be evaluated as part of the mechanical architecture, rather than simply as an electrical component.

3. Custom Dimensions for Real PCB Designs

Standard connector dimensions do not always match a customer's PCB.

For OEM and ODM projects, we can configure the connector according to the required:

• Pitch;
• Pin count;
• Number of rows;
• Insulator height;
• Contact length;
• PCB tail length;
• Mating height;
• Plating;
• Mounting method;
• Housing dimensions.

This is particularly useful for projects where the connector must fit an existing PCB footprint or mechanical enclosure.

Industry suppliers also commonly offer customized pin length, PC-tail length, and insulator height for female-header products.

THT or SMT Side Entry?

The mounting method should be determined during the PCB design stage.

Applications

Consumer Electronics

Suitable for internal PCB connections in:

• Consumer electronic devices
• Smart home equipment
• Display equipment
• Control panels
• Embedded electronic devices

The compact 1.27 mm option can be considered where PCB space is constrained.

Industrial Control Equipment

Side-entry female headers can be used in:

• PLC-related equipment
• Industrial controllers
• Measurement instruments
• Control boards
• Automation equipment
• Industrial communication modules

The selection should be based on the required electrical rating, environment and assembly method.

Communication Equipment

Potential applications include:

• Network equipment
• Communication control boards
• Interface modules
• Signal-processing boards
• Embedded communication systems

For compact communication equipment, the 1.27 mm or 2.00 mm pitch can be evaluated when PCB density is an important design consideration.

Automotive Electronics

Potential applications include:

• Automotive control modules
• Display control boards
• Instrumentation electronics
• Vehicle interface modules
• Infotainment-related PCB assemblies

Automotive applications should be evaluated against the actual temperature, vibration, electrical, and environmental requirements rather than relying only on the connector's nominal configuration.

Medical and Measurement Equipment

The connector can also be considered for:

• Test instruments
• Measurement equipment
• Control electronics
• Diagnostic equipment
• Industrial meters

For these applications, engineers should specify the required material, contact plating, electrical rating and environmental conditions during quotation.
