Molex Mini-Fit Jr Series Straight Through Hole PCB Header 12 Contacts 4.2 mm Pitch 2 Row Shrouded 39-28-9128

Molex 39-28-9128 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-performance connector designed for wire-to-board power interconnections. Featuring 12 contacts arranged in 2 rows with a 4.2 mm pitch, this shrouded header provides superior protection against damage and misalignment.

Engineered for demanding industrial and electronic applications, the connector supports currents up to 9A per circuit and withstands voltages up to 600V. Its fully isolated terminals minimize risks caused by debris and mishandling. The scoop-proof housing design prevents damage to pin terminals during angled mating operations.

Polarization and keying features ensure correct orientation and prevent mismating, while the positive locking mechanism guarantees a secure connection resistant to shock and vibration. An audible click confirms full mating engagement, enhancing installation confidence.

Available variants include models with snap-in plastic PCB peg locks and PCB mounting flanges, allowing tailored mechanical fixation on circuit boards. Constructed with durable nylon housing and gold-plated brass contacts, the connector delivers excellent mechanical and electrical reliability.

This PCB header series is ideal for industrial automation equipment, office machines, consumer electronics, and networking devices requiring high current and density in wire-to-board connections. Operating temperature ranges from -40°C to 105°C ensure suitability in harsh environments.

Handles up to 9A current per circuit, ensuring reliable power transmission. Features fully isolated terminals to protect against debris and damage. Scoop-proof housings prevent contact damage during mating. Includes polarization and keying to prevent misalignment and mismating.
