3M 3000 Series Straight Through Hole PCB Header, 20 Contacts, 2.54 mm Pitch, 2 Row, Shrouded N3428-6302RB

3M N3428-6302RB 3000 Series Straight Through Hole PCB Header is engineered for reliable power and data transmission with 20 contacts in a two-row layout and 2.54 mm pitch spacing. Its copper alloy contacts with gold plating resist corrosion and ensure consistent electrical performance. The shrouded housing provides four-wall protection to prevent damage from rough handling and contaminants, making it suitable for industrial and aerospace applications.

The header is designed for both board-to-board and wire-to-board connection systems and features a through-hole mount with solder tail terminations to securely fasten to printed circuit boards. Its thermoplastic polyester casing withstands high temperatures up to 260°C, supporting lead-free soldering processes commonly used in modern electronics manufacturing.

This connector operates reliably across a broad temperature range of -55°C to 105°C and accommodates a current rating of 1A and voltage up to 25V. The rolled pin design enhances retention on PCBs even under vibration, making it ideal for use in demanding environments including control dashboards, single board computers, aerospace components, and LED signaling systems.

The 3M 3000 Series headers also feature ejection latches for secure yet easily removable connections, and polarisation keys are optionally available to prevent mismating. The shrouded design combined with multiple polarisation slots allows for quick, precise alignment and robust connectivity. These headers meet the demands of industrial, electronic, and aerospace manufacturing sectors.

Constructed with copper alloy contacts for superior conductivity and durability. Gold-plated contacts provide excellent corrosion resistance and stable signal quality. Shrouded four-wall casing protects contacts from damage and contaminants.

Suitable for 20 contacts in two rows with a 2.54 mm pitch standard spacing. Thermoplastic polyester housing withstands high lead-free soldering temperatures up to 260°C. Through-hole mount type with solder tail termination for strong PCB integration.

Operating temperature range from -55°C to 105°C supports harsh environmental conditions. Designed for versatile board-to-board and wire-to-board connector systems.
