50 Position Connector Receptacle, Center Strip Contacts Surface Mount Gold

The DF40HC series connector is a high-density, low-profile board-to-board interconnect solution designed for compact electronic assemblies requiring reliable signal integrity and mechanical robustness. This connector is intended for parallel board stacking applications where space constraints demand minimal height and fine contact pitch. It provides secure mating with precise alignment features and is optimized for high-speed signal transmission in advanced electronic systems such as portable devices, embedded modules, and industrial electronics.

Mechanical Characteristics

The connector features a slim, rectangular form factor suitable for high-density PCB layouts. It incorporates a fine-pitch contact arrangement to maximize signal routing efficiency within a limited footprint. The housing is constructed from high-temperature thermoplastic material to support standard reflow soldering processes. Contacts are designed to ensure consistent normal force, enabling stable electrical connection under vibration and mechanical stress. The mating interface includes polarization features to prevent incorrect insertion and to guide proper alignment during assembly.

Electrical Characteristics

The connector is engineered to support reliable signal transmission across multiple contact points with low contact resistance and stable impedance characteristics. It is suitable for both signal and low-power applications. Contact plating is optimized to maintain conductivity and minimize wear over repeated mating cycles. The design supports high-speed data transfer by reducing crosstalk and maintaining signal integrity across adjacent contacts.

Environmental Characteristics

The component is designed to operate within standard industrial temperature ranges and is compatible with lead-free reflow soldering processes. Materials used in construction comply with common environmental and regulatory standards for electronic components. The connector maintains performance under typical environmental stresses such as humidity, temperature variation, and mechanical vibration.

Materials and Finishes

The insulating housing is manufactured from a high-performance thermoplastic with appropriate flammability rating. Contacts are formed from copper alloy and plated with a noble metal finish over a suitable underlayer to ensure durability, corrosion resistance, and consistent electrical performance.

Application Notes

This connector is intended for use in applications requiring compact stacking of printed circuit boards with reliable electrical interconnection. Proper PCB layout, including pad design and solder mask considerations, is essential to ensure optimal performance. Care should be taken during handling and assembly to avoid damage to fine-pitch contacts. Designers should follow recommended land patterns and assembly guidelines provided by the manufacturer to achieve consistent solder joints and mechanical stability.
