1. 4.2mm Pitch Design for Reliable and Convenient Installation

The KH-A42002-2X2A features a 4.2mm pitch design, providing sufficient spacing between contacts while maintaining a compact overall structure. This design helps facilitate PCB layout and assembly. The 2×2P configuration provides four connection points, making it suitable for electronic devices that require multiple electrical connections.

The connector uses a through-hole mounting design and can be directly installed on a PCB and secured through soldering. Compared with some surface-mount structures, the through-hole design provides a straightforward installation method and reliable mechanical fixation, making it suitable for electronic equipment requiring stable board-level connections.

2. 7A Rated Current for Various Electrical Applications

Current-carrying capability is an important consideration when selecting a connector. The KH-A42002-2X2A is rated at 7A and supports both AC and DC current transmission. It can be used for internal power connections and other electrical connection applications that require a moderate current-carrying capacity.

The connector has a rated voltage of 600V AC/DC. Subject to the actual application conditions and relevant design requirements, it can be used in power equipment, industrial control systems, and various electronic products. During actual product design, the allowable operating current should also be evaluated based on factors such as wire size, PCB layout, ambient temperature, and installation conditions.

3. Brass Contacts with Tin Plating for Stable Conductivity

The contacts of the KH-A42002-2X2A are made of brass and finished with tin plating. Brass provides good electrical conductivity and mechanical strength, meeting the basic requirements for connector contacts in terms of electrical performance and structural durability. The tin-plated surface also helps provide suitable solderability and surface protection.

In terms of electrical performance, the connector features a maximum contact resistance of 20mΩ and a minimum insulation resistance of 1000MΩ. It also provides a dielectric withstand voltage of 1500V AC/minute, making it suitable for a range of electronic equipment requiring reliable conductivity and insulation performance.

4. PA66 Insulating Material for Standard Operating Environments

The insulating housing is made of PA66 and features a UL94-V-2 flame-retardant rating. PA66 provides good mechanical strength and heat resistance, making the connector suitable for various common electronic and electrical applications.

The operating temperature range is -25°C to +85°C, covering many applications such as industrial control equipment, smart devices, instrumentation, and general electronic products.

The connector is available in a transparent color. Its 12.8mm board height along the Z-axis and 11.4mm base width along the Y-axis can provide useful dimensional references for PCB layout, mechanical clearance, and internal equipment design.

5. Suitable for Various PCB Wire-to-Board Applications

As a wire-to-board connector, the KH-A42002-2X2A is primarily designed to establish electrical connections between wires and PCBs. Its 4-position 2×2 arrangement provides a compact solution for multiple electrical connections, while the 4.2mm pitch facilitates PCB layout and assembly.
