The 644740-1 Rectangular Connectors - Headers, Male Pins is a device intended for connection between two electrical circuits. It consists of two mating female and male ends, as well as a plastic housing. Available in several different sizes, the 644740-1 allows for both power and signal connections. It is commonly used in applications such as large printed circuit boards, back-plane assemblies, control panels, and rack mount equipment.

The 644740-1’s construction consists of two shell sizes, plated steel machined contacts, and a one-piece locking latch mechanism. The machined contacts are smooth and feature an 8mm pitch. The latch taper and thread are compatible with regular and reverse-taper receptacles. As for the plastic housing, it includes double-hinged clamshell covers, and it is UL 94V-0 rated for excellent resistance against environmental conditions and chemicals.

Users should take into consideration that the 644740-1 is intended for a low power current of up to 3A, and a frequency range of 0 – 10GHz. The device features excellent contact reliability thanks to the coaxial self-grounding effect. Plus, the 644740-1’s robust plastic housing resists scrapes, dents, and fatigue. This means it does not require support or shielding during operation.

The 644740-1’s working principle is based on the electrical connection between two points. The male end features four contact tips which extend outward, allowing for easy insertion into the mating female connector. When locked in place, the four contact tips provide an electrically and mechanically secure connection which is hard to disrupt without causing significant damage to the connector and the circuit.

Thanks to its low power current application, the 644740-1 is often used in printed circuit boards, back-plane assemblies, control panels, and rack mount equipment. Additionally, its robust plastic housing makes it suitable for medical applications, as well as for harsh industrial environments. Further, due to its small size, the 644740-1 is a great choice for space-saving designs.

The 644740-1 Rectangular Connectors - Headers, Male Pins offers excellent contact reliability, a robust plastic housing, and easy mating. This makes it ideal for use in several types of applications, including medical/industrial settings, printed circuit boards, and rack mount equipment. Plus, its one-piece locking latch mechanism makes installation effortless and its UL94V-0 rating promises superior environmental and chemical resistance.
