Norcomp 25 Way Straight Female D-Sub Connector 2.77 mm Pitch Through Hole, 5A, 500V, 4-40 Board Lock, 171-025-213R911

The Norcomp 171-025-213R911 is a high-quality, straight D-Sub connector, offering 25 contact ways and engineered for robust board-level interconnects in industrial and commercial electronic applications. This model features a standard 2.77 mm pitch, through hole mounting type, and includes a female connector gender with a 4-40 board lock for stable PCB installation.

Engineered for reliability, this connector handles a current of up to 5 amperes and can withstand voltages up to 500 volts, meeting the rigorous needs of electronic interface systems. The solder termination ensures a secure and electrically sound connection, minimizing performance losses and providing longevity in soldered assemblies.

The connector’s shell is made from nickel-plated steel for superior strength, corrosion resistance, and electrical shielding. Contacts are constructed from brass and finished with high-conductivity gold flash plating, resulting in low contact resistance and enhanced signal transmission.

With an operating temperature range from minus 50°C to 100°C, the 171-025-213R911 is well suited for both industrial and laboratory settings, including control panels, instrumentation, test equipment, and computer interface applications. The insulator, made from glass-filled thermoplastic, withstands soldering processes up to 260°C, ensuring mechanical stability during assembly and operation.

This D-Sub connector provides a secure interface due to its 4-40 board lock integrated mounting hardware. Its nickel shell incorporates grounding indents, enhancing both electromagnetic compatibility and retention force, especially in environments with vibrations or repeated connections and disconnections.

Common applications include use in industrial automation, data acquisition devices, laboratory equipment, factory machinery controls, and PCB assemblies requiring reliable, high-density connector interfaces. It is especially suited for standard density D-sub configurations in commercial and industrial installations.

For engineers and system integrators seeking precision and dependability, the Norcomp 171-025-213R911 offers a proven connector solution aligned with modern electronics and automation requirements.
