Molex Mini-Fit Jr Series Straight Through Hole PCB Header 20 Contact 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 high-quality electrical connector featuring 20 contacts arranged in 2 rows with a 4.2 mm pitch. This shrouded PCB header is part of the Mini-Fit Junior power connector family, designed to handle up to 9 amperes per circuit, making it suitable for high power applications requiring reliable connections.

The connector housing is molded from durable nylon material, providing excellent electrical insulation and mechanical strength. The contacts are male, made of brass and plated with tin to ensure optimal conductivity and corrosion resistance. The through hole mount type allows for robust soldering to printed circuit boards, enhancing mechanical retention and electrical performance.

Designed for use in demanding industrial and consumer electronics applications, this header incorporates scoop-proof shrouding to prevent damage to contacts during mating at severe angles. It also features polarization and keying to prevent mismating with corresponding receptacles.

The header includes a positive locking mechanism providing a secure mating connection, confirmed by an audible click, thereby reducing the risk of accidental disconnects under mechanical shock or vibration. It operates reliably in a wide temperature range from -40°C to 105°C, accommodating various environmental conditions.

Common applications include consumer white goods, office equipment, industrial automation systems, networking equipment such as servers and switches, and other electronic assemblies requiring high current, compact wire-to-board connections.

Supports up to 9A per circuit for high current handling. 20 contacts in 2-row configuration with 4.2mm pitch. Durable nylon housing with shrouded scoop-proof design. Male brass contacts plated with tin for conductivity and corrosion resistance.

Positive locking mechanism with audible click ensures secure mating. Polarization and keying features prevent misalignment and mismating. Through hole mount type for reliable PCB attachment. Operating temperature range -40°C to 105°C suits various environments.
