Molex Mini-Fit Jr Series Straight Through Hole PCB Header 20 Contacts 4.2 mm Pitch 2 Row Shrouded 39-29-9206

Molex 39-29-9206 Mini-Fit Jr Series Straight Through Hole PCB Header is a robust electrical connector designed with 20 male contacts arranged in 2 rows with a 4.2 mm pitch. It forms part of the Mini-Fit Junior power connector system, ideal for high current and high density wire-to-board interconnection needs across industrial and commercial electronic equipment.

This PCB header supports a maximum current of 9A per circuit, making it suitable for demanding power applications. Its nylon housing is scoop-proof to prevent damage to pin terminals during angled mating and incorporates polarization and keying features to ensure correct alignment and prevent mismating. Positive locking with audible click ensures a secure connection resistant to shock and vibration.

The connector uses brass contacts plated with tin for effective conductivity and corrosion resistance, terminated with soldering on through-hole mounting. It operates reliably between -40°C and 105°C, backing diverse operating environments. The fully isolated terminals offer protection against debris and arcing, enhancing connector safety and durability.

This Mini-Fit Jr PCB Header series is widely used in consumer white goods, office equipment, industrial control and network equipment such as rack-mount servers, routers, and switches. It provides design flexibility for wire-to-wire and wire-to-board connections in dense electronic assemblies.

Handles up to 9A current per circuit for robust power applications. Durable nylon shrouded housing protects against contact damage at various mating angles. Polarization and keying features prevent connection mismatches.

Positive locking mechanism with audible click for secure mating. Brass contacts with tin plating ensure reliable electrical performance. Wide operating temperature range from -40°C to 105°C. Fully isolated terminals for protection against arcing and debris.
