11 lengths available from 0.5 m to 30 m for flexible RS232 serial connections; plug and play. 28 AWG conductors with doublelayer shielding and goldplated pins for stable, fast data transmission and reliable contact. DB9 three optional interfaces: male to male, male to female, and female to female. The male end provides pins and the female end provides holes. Metal connector shells are resistant to insertion and extraction, wearresistant, and corrosionresistant for durable use. Compatible with standard RS232 DB9 devices for direct data communication without adapters or converters. Suitable for a range of environments and applications where a robust RS232 connection is required. Use scenarios: Connecting a PC or laptop to legacy serial devices such as modems, barcode scanners, CNC controllers, PLCs, or other equipment with a DB9 port for data transfer or configuration. Development and testing with serial devices or embedded systems that use RS232 interfaces, enabling reliable terminal access and debugging. Providing serial console access to network equipment or industrial controllers that feature a DB9 RS232 port for setup, monitoring, or maintenance. Ideal for installations where different end configurations are needed, thanks to the three interface options (maletomale, maletofemale, femaletofemale) with a pinend male and holeend female.
