Reliable 9-Pin RS-232 DB9 Male Connector for Secure Serial Communication: Straight Solder Type for Cable Assemblies
The 9-Pin RS-232 DB9 D-Subminiature Male Connector (straight, wire-solderable) is a robust, industry-standard solution for building or repairing serial cables. Featuring easy-to-work solder cups for individual conductors, a durable metal shell, and precisely aligned pins, it delivers a secure, low-noise connection for asynchronous RS-232 data links. Its compact form factor and high-quality contact plating ensure dependable signal integrity in professional-grade applications.
Engineered for reliability and compliant with RS-232C signaling, this DB9 male connector is ideal for custom cable harnesses used in industrial equipment, embedded systems interfaces, instrumentation, and legacy computing. The straight body format fits most standard backshells/hoods and accommodates common wire gauges for quick, clean hand-soldering.
