KH-2FH90-2X2P-H6.35 Right-Angle Female Header: Small-Pitch Connectivity for Compact Circuit Design

In today's rapidly evolving electronics industry, electronic devices are becoming increasingly compact and highly integrated. As an essential component of circuit systems, connectors play an important role in the overall stability and reliability of electronic equipment. Their structural design, mounting method, and electrical performance can directly affect the performance of the entire system. Especially in PCB applications where board space is limited, small-pitch and high-density pin headers and female headers can effectively save PCB space while providing stable signal and power connections.

The above specifications show that the KH-2FH90-2X2P-H6.35 is designed specifically for the connection requirements of compact electronic equipment. Its 2mm pitch and dual-row configuration provide a relatively high connection density within limited PCB space, while the right-angle design offers greater flexibility for different PCB layouts.

III. 2×2P Dual-Row Design for High Connection Density and Space Efficiency

The KH-2FH90-2X2P-H6.35 features a 2×2P contact configuration with a dual-row design, providing a compact pin arrangement. Both the contact pitch and row spacing are 2mm. Compared with conventional female headers with larger pitches, this design can achieve a higher connection density within the same PCB area, making it suitable for compact control boards, module boards, consumer electronics, and other applications where PCB space is limited.

The dual-row configuration not only supports multiple contact connections but also improves PCB space utilization. For applications where multiple connectors need to be arranged on a limited board area, the compact design provides additional space for overall circuit layout and component placement.

IV. Right-Angle Design for Greater PCB Layout Flexibility

In terms of mounting configuration, the KH-2FH90-2X2P-H6.35 adopts a 90° right-angle design. Compared with conventional vertical female headers, the right-angle configuration changes the connection direction, allowing mating connectors or wires to be routed horizontally along the PCB.

This design is particularly suitable for equipment where vertical space is restricted or side-entry connections are required. By making better use of horizontal space, the connector can help reduce the amount of vertical space occupied by the mating components, contributing to a more compact internal device structure.

At the same time, the right-angle configuration provides engineers with more options during PCB layout design, making it easier to balance electrical connection requirements with mechanical structure and assembly requirements.

V. 2mm Pitch and Square-Hole Design for Reliable Mating

The product features a 2mm pitch and square-hole contact structure, allowing it to mate with compatible pin headers and other corresponding connectors. The 2mm small-pitch design helps reduce the PCB footprint of the connector, while the square-hole structure provides a stable contact interface when used with compatible mating components.

Although connectors are relatively small components, their long-term operating stability is important to the reliability of the overall electronic system. In equipment that requires repeated mating cycles or long-term operation, selecting properly matched connectors can help reduce connection-related issues and maintain stable system performance.

VI. 4mm Insulator Height for Compact PCB Applications

The KH-2FH90-2X2P-H6.35 features a 4mm insulator height. The height of the insulating body is an important dimensional parameter when selecting and designing connectors. In practical product development, it should be considered together with PCB thickness, surrounding component heights, enclosure dimensions, and other mechanical requirements.

The 4mm insulator height provides a compact overall configuration while meeting the structural requirements of the connector. For electronic devices with limited internal space, a compact connector design can better accommodate high-density component layouts and leave more usable space for PCB design.

VII. 1.5A Rated Current for Various Connection Requirements

In terms of electrical performance, this model has a rated current of 1.5A. When operated within the specified design conditions and application requirements, it can be used for corresponding signal connections and low-power power connections.

Rated current is one of the key parameters that engineers need to consider when selecting a connector. In practical applications, other factors such as operating voltage, ambient temperature, load conditions, number of contacts, and PCB design should also be taken into consideration to ensure reliable connector performance.

Therefore, when selecting the product, it is recommended to match the connector specifications with the actual electrical parameters of the circuit and avoid operating beyond the connector's rated conditions.

VIII. Wide Operating Temperature Range for Different Working Environments

The KH-2FH90-2X2P-H6.35 has an operating temperature range of -40°C to +105°C, covering a relatively wide range of operating conditions. For industrial control systems, automation equipment, communication devices, and other electronic products operating under different ambient temperatures, the temperature capability of a connector is an important factor in determining its suitability for a particular application.

The wide operating temperature range provides support for applications under various environmental conditions. However, during actual use, the connector should still be selected according to the operating environment of the complete equipment and the specific application requirements. Installation and operation should also comply with the applicable design specifications and product requirements.

IX. Product Applications

As a compact connector component, the KH-2FH90-2X2P-H6.35 is mainly intended for applications requiring 2mm pitch, dual-row, right-angle connections. Its compact size and flexible configuration make it suitable for different PCB layout requirements.

Based on its structural characteristics, this model is particularly suitable for electronic products where PCB space and connection direction are important considerations. During product development, engineers can select the appropriate installation configuration according to the available internal space, PCB layout, and required connection direction.

Depending on the specific circuit requirements, the product can be considered for applications including control boards, interface boards, electronic modules, instrumentation, communication equipment, and other electronic devices requiring board-to-board or PCB-level connections.
