Molex Straight Pin PCB Header, 3 Way, 2.54mm Pitch - 6410 Series - 22-27-2031

Attach wires to your printed circuit board (PCB) with this straight pin header from Molex. The nylon material provides good electrical insulation for safety, while the tin-plated brass contacts are highly conductive, so they offer good connectivity. As this contact material also resists rust build-ups, it ensures a long-lasting, durable connection, even when used in demanding environments. Thanks to the unit's solder termination method, you're assured of a secure connection that keeps moisture and dust out to maintain optimal performance.

• Designed for through-hole mounting for ease of installation

• Straight body orientation for simple organisation of connections

• Current rating of 4A per contact for use in low-current applications

• Polarised to mating part to ensure proper insertion and reduce the risk of damage to the connection

• Compatible with housings in Molex's 2695, 6471 and 7880 series for added versatility

Applications

• Automotive machinery

• Home appliances

• Data and communications

• Medical technology

Will this header come loose easily?

This header has a straight friction lock mechanism to keep the connection securely in place once mated. This means it won't easily disconnect, even when subjected to heavy-duty vibrations from machinery.
