Molex Mini-Fit Jr Series Straight Through Hole PCB Header 14 Contact 4.2 mm Pitch 2 Row Shrouded 39-29-9142

Molex 39-29-9142 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-quality 14-contact connector with 4.2 mm pitch and 2 rows, engineered for robust wire-to-board connections in demanding environments.

This PCB header can handle up to 9 amperes per circuit, making it suitable for high current applications such as industrial automation equipment, consumer electronics, office machines, and networking hardware. Its nylon housing ensures electrical insulation and mechanical durability, while the brass contacts with tin plating offer excellent conductivity and corrosion resistance.

The connector incorporates a positive locking mechanism that secures the connection firmly and prevents accidental unmating caused by shock or vibration. The polarization and keying of the housing ensure proper mating alignment, eliminating potential mismatches during assembly. The shrouded design and scoop-proof housing protect the pins from damage due to debris or misalignment and allow mating even at severe angles without harm.

Termination is via solder on a through-hole PCB mount, providing reliable mechanical and electrical connection. The connector operates effectively in a temperature range of -40°C to 105°C, suitable for typical industrial and commercial applications.

Additional design options include versions with snap-in plastic PCB peg locks and mounting flanges for enhanced retention on printed circuit boards. These Mini-Fit Jr headers are compliant with industry standards although not formally approved by specific standards bodies and are manufactured in China.
