Molex Mini-Fit Jr Series Straight Through Hole PCB Header, 8 Contacts, 4.2 mm Pitch, 2 Row, Shrouded 39-29-9089

Molex 39-29-9089 Mini-Fit Jr Series PCB Header is a high-performance, shrouded straight through hole connector designed for PCB applications requiring reliable wire-to-board connections. This 8-contact header features a 4.2 mm pitch and two rows, constructed with a durable nylon housing and brass contacts plated in gold to ensure conductivity and resist corrosion.

These Mini-Fit Junior connectors can carry up to 9A per circuit, making them highly suitable for high current and high-density electronic applications across industrial automation, consumer white goods, office equipment, and networking hardware such as rack-mount servers, routers, and switches.

Designed with fully isolated terminals and scoop-proof housings, the connector protects against debris, arcing, and physical damage during handling. The housings include polarization and keying mechanisms to prevent misalignment or mating errors, supported by a positive locking feature that ensures a secure connection with an audible click to confirm mating.

The connector uses a wire-to-board interface with male contact gender and solder termination for mounting to printed circuit boards. It supports operating temperatures from -40°C to 105°C and withstands voltages up to 600V, making it reliable for harsh and demanding environments.

Versions are available with additional PCB retention pegs and mounting flanges for enhanced mechanical security. The product is manufactured in Mexico and does not carry specific approvals but aligns with industry standards for power connectors and PCB Headers.

Rated for up to 9A current per circuit. Fully isolated terminals prevent arcing and damage. Scoop-proof housing avoids contact damage during severe angle mating. Polarized and keyed to ensure correct mating orientation. Positive locking mechanism with audible click for secure connection.

Straight orientation with 4.2 mm pitch and 2-row contact layout. Compatible with through hole PCB mounting and solder termination. Operating temperature range from -40°C to 105°C. Gold-plated brass contacts enhance durability and conductivity.

This Mini-Fit Jr Series PCB Header connector is ideal for power and signal interconnections in industrial, laboratory, HVAC, networking, and manufacturing equipment requiring reliable, high current wire-to-board connections.
