Molex Mini-Fit Jr Series PCB Header 24 Contacts 4.2 mm Pitch 2 Row Shrouded Through Hole 600V 9A 39-29-9243

Molex 39-29-9243 Mini-Fit Jr Series PCB Header is a high-quality, shrouded power connector designed to provide reliable wire-to-board connections with 24 male contacts arranged in 2 rows and a 4.2 mm pitch. It supports currents up to 9A per circuit and operates at up to 600V voltage, ideal for demanding electronic components and power distribution applications.

The connector features fully isolated terminals that guard against debris and arcing, ensuring long-lasting performance and safety in harsh environments. The scoop-proof housing protects the pin terminals from damage when mated at severe angles, enhancing durability during assembly and maintenance.

Its built-in polarization and keying features prevent incorrect mating with receptacles, reducing error risk during installation. A positive locking mechanism keeps the connector securely engaged with an audible click to confirm perfect mating, vital for industrial and commercial applications subjected to vibration and shock.

This PCB header is constructed with a nylon housing material approved to UL94V-0 or UL94V-2 standards, brass contacts, and tin plating, offering excellent mechanical and electrical performance. It operates within a temperature range of -40°C to 105°C, suitable for various ambient conditions encountered in industrial and consumer electronic devices.

Available with optional snap-in plastic PCB retention pegs and mounting flanges, it ensures stable placement on circuit boards, facilitating efficient manufacturing processes. Common applications include consumer white goods, office equipment, industrial automation machinery, network devices such as routers and switches, and rack-mount servers, where secure, high-current connections are essential.
