Rectangular Connectors - Headers, Male Pins

The 70246-5002 is a rectangular connector developed by Samtec featuring a number of wide varieties of headers and male pin configurations. This connector is mainly used to provide a cost effective electrical connection between two printed circuit boards, a device and a PCB, or a PCB and another PCB. The product is known for its versatility and is available in single and dual header configurations for multiple applications.

Aperture options range from 0.006″ to 0.187″ and the product is rated for an electrical performance of 250V. The design of 70246-5002 enables the connectors to be selectively mated in stacks with no visible interface. This makes it ideal for applications such as switching power supplies and signal routing in controls and automation equipment.

Features and Benefits

• Compact design for higher packing density.
• Zero Visible Interface™ allows mating stacks.
• Low Profile.
• Supports a wide range of frame heights.
• Backpanel mountable.
• Improved Signal Quality.
• Improved Shielding.
• Ground Termination Pad.
• Available in Single and Dual Header Configurations.
• Aperture Options ranging from 0.006″ to 0.187″

Applications

The Samtec’s 70246-5002 is a versatile rectangular connector applicable for a number of applications, notably PCBs, framed controllers, and devices. Specifically, this product is used in the following areas:

• Signal routing in controls and automation equipment.
• Switch gear power supplies.
• Environmental testing.
• Industrial control units.
• Instrumentation equipment.
• Power conditioning systems.

Working Principle

The working of 70246-5002 can be understood by breaking down the process into four individual stages. The first stage is selection of the appropriate link-chain, which consists of a box-style female header, an integrated male pin, and a board retainer with associated fasteners. Each link-chain is designed with N- or T-shaped female header, which are inserted into the through-board hole prior to the male pin. Here, two designs can be used, either the spring-actuated pin or a non-spring-actuated stay-in-place pin. In the second stage, the female header fits into the board receptacle, which is found in the printed circuit board.

In the third stage, the male pin extends from the board receptacle, which is found on the socket head and allows for the transmission of an electrical current. The fourth and final stage is associated with the retention of the socket lid, which keeps the male and female heads securely connected and prevents accidental contact disconnection. Upon completion of the stages, the 70246-5002 rectangular connector is ready to provide high-performance electrical connectivity.

Design Considerations

When designing a printed circuit board with the 70246-5002 rectangular connector, it is important to consider the following factors;

• The MSL level, which should be sufficient for the assembly process. Higher MSL levels will also be required if reliable performance is to be expected over time.
• The sizing of board holes. This should match the size of the female header connector and board retainer.
• The type of board materials. Non-metallic materials are ideal for this product’s internal conductive caps.
• The types of solder used. For surfaces that require a permanent connection, a lead free solder is recommended.
• The current carrying capacity. This depends on the panel thickness and the type of connector assembly used.

Conclusion

The Samtec’s 70246-5002 is a versatile rectangular connector designed to provide a cost effective electrical connection between two PCBs, a device and a PCB, or two PCBs. It is designed with a number of features such as zero visible interface, improved shielding, and improved signal quality. This product is mainly used to provide signal routing in controls and automation equipment and is suitable for a wide range of applications. When designing with the 70246-5002, it is important to consider a number of factors such as the MSL level, sizing of board holes, board materials, types of solder to be used, and current carrying capacity.
