Product Description
Molex 39-28-8200 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-quality 20-contact electrical connector with a 4.2 mm pitch arranged in 2 rows. It features a shrouded, straight orientation and is designed to provide secure wire-to-board connections for power distribution needs up to 9A per circuit and 600V operating voltage.
The housing is made from durable nylon material, providing scoop-proof protection to prevent pin contact damage when mated at severe angles. The fully isolated terminals reduce the risk of arcing and damage caused by mishandling or debris. Contact material is brass with tin plating, ensuring reliable conductivity and corrosion resistance.
The connector incorporates polarization and keying features to prevent misalignment and mating errors. A positive locking mechanism supplies a secure connection and an audible click confirms proper mating, which is critical for applications subjected to shock or vibration.
This PCB header is suitable for a range of industrial and commercial electronic applications, including consumer white goods, industrial automation equipment, networking hardware such as rack-mount servers, routers, and switches. Versions of this connector also include options with snap-in plastic peg locks and mounting flanges for enhanced PCB retention.
The connector is rated for operation between -40°C and 105°C, suitable for harsh environments and demanding reliability requirements. It meets industry standards for power connectors though it does not have explicit certifications.
