Molex Mini-Fit Jr Series Straight Through Hole PCB Header 24 Contacts 4.2 mm Pitch 2 Row Shrouded 39-29-9242

The Molex 39-29-9242 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-performance connector designed for demanding electronic applications requiring reliable and secure wire-to-board connections. This model features 24 male contacts arranged in 2 rows with a 4.2 mm pitch. Its nylon housing is shrouded and scoop-proof, providing excellent protection to the pin terminals against damage during mating. The connector's fully isolated terminals prevent ingress of debris and reduce the risk of arcing or electrical faults.

Operating at voltages up to 600V and currents up to 9A per circuit, this PCB header supports a wide range of industrial and commercial applications including consumer white goods, office equipment, industrial automation, rack-mount servers, and networking devices such as routers and switches. It is engineered with polarization and keying features to prevent incorrect connections, while a positive locking mechanism and audible click guarantee secure and reliable mated conditions even under shock and vibration.

The termination type for this connector is solder through hole, enabling strong mechanical and electrical attachment to printed circuit boards. Constructed from brass contacts plated with tin, it offers excellent conductivity along with corrosion protection. Its operational temperature range from -40°C to 105°C ensures performance in harsh environments. Versions with PCB retention pegs and mounting flanges are available for enhanced PCB retention and mounting flexibility.
