Product Description

Molex 39-29-9043 Mini-Fit Jr Series PCB Header is a high-performance, 4-contact, 4.2 mm pitch, 2-row, shrouded connector for through-hole mounting on printed circuit boards. Offering a rated current of 8A and a voltage rating up to 600V, this connector is designed to support demanding power relationships in industrial and commercial electronic applications.

The nylon housing provides robustness and insulation, while the brass contacts with tin plating guarantee reliable conductivity and corrosion resistance. The connector includes fully isolated terminals to guard against debris and arcing, enhancing safety during operation and handling.

The scoop-proof design protects the contacts during mating, and the polarization and keying features prevent misalignment or mismating, ensuring a secure and precise connection every time. A positive locking mechanism with an audible click confirms proper engagement, and versions are available with PCB retention pegs and mounting flanges for added stability.

This Mini-Fit Jr Series header is well suited for consumer electronics, office equipment, industrial automation machinery, and networking hardware such as rack-mount servers, routers, and switches, where reliable power and signal connections are critical. It operates reliably over a temperature range of -40°C to 105°C and supports through-hole mounting for mechanical strength.

Handles currents up to 8 amps per circuit reliably. Features a 4.2 mm pitch and two rows of contacts for compact installation. Constructed with a nylon housing and brass contacts plated with tin. Provides a positive locking mechanism with an audible click to confirm mating.
