Molex Straight Pin PCB Header, 4 Way, 2.54mm Pitch - 6410 Series - 22-27-2041

Need a reliable way to connect wires to a printed circuit board (PCB)? Use this straight pin header from Molex. It has four contacts for connection to up to four circuits, and its 2.54mm pitch makes it a good choice for saving space on your PCB. The header can withstand a current of up to 4A per contact for use in low-current applications. Its tin-plated brass contacts offer excellent resistance to corrosion, so can rely on it for minimal wear and a long-lasting connection.

• Nylon resin material for impact resistance and durability

• Friction lock holds the header securely in place, even when used with high-vibration machinery

• Through-hole mounting style for simple installation

• Wide operating temperature range of -40°C to +80°C for use in demanding environments

Applications

• Gaming systems

• Home security systems

• Medical equipment

• Industrial automation

Can I safely solder this header?

This header is safe to solder at a process temperature of up to +235°C for a single cycle. It's wave-capable, meaning you can push the header into place during soldering as long as soldering occurs at the through-hole only.
