KH-A42002-2X3A Wire-to-Board Connector: 4.2mm Pitch and 7A Rated Current

Wire-to-board connectors are mainly used to establish electrical connections between wires and PCBs. They offer easy installation, reliable connections, and convenient maintenance, making them widely used in power equipment, industrial control systems, household appliances, lighting equipment, and other electronic products. Depending on application requirements, wire-to-board connectors are available in different pin configurations, pitches, mounting methods, and electrical specifications.

Kinghelm KH-A42002-2X3A is a through-hole wire-to-board header featuring a 2×3P configuration, 4.2mm pitch, and 6-pin straight-through-hole design. It has a rated current of 7A, a rated voltage of 600V, and an operating temperature range of -25°C to +85°C. The connector uses PA66 insulation material with a UL94-V2 flammability rating, while the terminals are made of brass with tin plating. The overall dimensions include a 12.8mm height above the PCB and an 11.4mm bottom width along the Y-axis, making it suitable for various wire-to-board connection applications.

2×3P Configuration for Multi-Circuit Connections

The KH-A42002-2X3A features a dual-row 6-pin configuration, with three pins in each row and a 4.2mm pitch. This design allows multiple circuits to be connected within a relatively compact PCB area while maintaining a clear and organized pin arrangement.

The connector uses a through-hole mounting method. Its pins can be inserted directly into the corresponding PCB holes and then soldered in place. This mature installation method provides a stable mechanical connection and is suitable for mass production of electronic equipment.

7A Rated Current for Power Connection Applications

The KH-A42002-2X3A has a 7A rated current and supports both AC and DC current transmission. Its rated voltage is 600V AC/DC. In addition, the connector features a maximum contact resistance of 20mΩ, a minimum insulation resistance of 1000MΩ, and a withstand voltage of 1500V AC for one minute.

These electrical specifications make the connector suitable for a variety of conventional electronic equipment. In practical applications, the actual current-carrying capacity should also be considered together with factors such as operating temperature, wire size, PCB design, and the surrounding environment.

PA66 Material and -25°C to +85°C Operating Temperature

The connector housing is made of PA66 material with a UL94-V2 flammability rating. The pins are made of brass and feature a tin-plated surface finish.

The operating temperature range is -25°C to +85°C, covering the requirements of many conventional electronic devices. The transparent housing provides a simple appearance and can be combined with different PCB and wire harness designs.
