Molex Mini-Fit Jr Series Straight Through Hole PCB Header, 4 Contact, 4.2 mm Pitch, 2 Row, Shrouded 39-29-0043

Molex 39-29-0043 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-quality connector designed for demanding industrial and electronic applications. It features 4 brass contacts with gold plating, arranged in 2 rows with a 4.2 mm pitch, providing reliable electrical connections capable of handling currents up to 9A per circuit at voltages up to 600V.

The connector housing is made from durable nylon material, featuring fully isolated terminals to protect against environmental contaminants and electrical arcing. The scoop-proof design reduces the risk of damage to the contact pins even when mated at severe angles, enhancing durability and reliability.

Polarization and keying features ensure precise alignment and prevent incorrect mating with the receptacle, thereby increasing safety and operational dependability. A positive locking mechanism provides a secure connection with an audible click confirming proper mating, which helps to avoid accidental disconnects in environments prone to vibration or shock.

Mounting is via a through hole PCB method, supporting wire-to-board interfacing commonly used in consumer white goods, industrial automation, office equipment, rack-mount servers, and network devices. Additional versions are available with snap-in plastic PCB peg locks or PCB mounting flanges for enhanced mechanical retention.
