Molex Mini-Fit Jr Series PCB Header 4 Contact 4.2 mm Pitch 2 Row Shrouded 39-29-3046

Molex 39-29-3046 Mini-Fit Jr Series PCB Header is a high-performance connector designed for power and signal board connections in industrial and commercial electronic systems. This PCB header features 4 brass male contacts with tin plating, arranged in 2 rows with a 4.2 mm pitch, housed in durable nylon material providing insulation and mechanical protection.

Designed for through-hole mounting, this connector provides a secure and stable mechanical bond to the PCB, suitable for applications requiring high current handling capability of up to 9 amperes per circuit. The shrouded housing protects the contacts from debris and accidental damage, and includes polarization and keying features to prevent incorrect mating, enhancing assembly reliability and preventing system faults.

The connector can operate safely in a wide temperature range from -40°C up to 105°C, making it suitable for harsh environments encountered in industrial automation, power supply units, office equipment, and consumer white goods. The snap-in plastic retention pegs and mounting flanges versions provide flexibility for PCB design and assembly processes.

Additional features include a positive locking mechanism that emits an audible click when fully mated, ensuring operator feedback and vibration-resistant connection stability. Rated for 600 volts, this PCB header is an excellent choice for high current and high voltage applications requiring compact and reliable wire-to-board connections.

Applications include industrial network equipment, data communication hardware such as servers and switches, office machinery, and consumer electronics requiring secure power distribution and signal integrity within PCB assemblies.

Supports up to 9A current per circuit for reliable power delivery. Constructed with nylon housing and brass male contacts plated with tin for durability. Through-hole mount type ensures secure PCB connection. Shrouded housing design protects contacts and prevents misalignment.

Operating temperature range from -40°C to 105°C suits diverse environments. Equipped with polarization and keying to prevent mismating with receptacles. Positive locking mechanism with audible click ensures secure mating.

Rated for 600V voltage allowing high voltage applications.
