RS232 DB9 Male-Male Serial Cable

This RS232 DB9 male-male serial cable is a standard communication cord for connecting RS232-enabled devices in industrial, networking and legacy equipment environments. It is commonly used to establish serial connections between computers, USB-to-serial adapters, network switches, routers, PLCs, CNC machines, industrial controllers, POS terminals, serial printers and other legacy RS232 peripherals.

The cable uses DB9 9-pin male connectors on both ends with straight-through wiring configuration, making it suitable for most general-purpose serial communication applications that require direct pin-to-pin connection. The molded connector housing provides strain relief and durability for frequent plugging, while the metal shielded shell helps reduce electromagnetic interference in industrial and cabinet environments.

Constructed with tinned copper conductors and shielded PVC jacket, this DB9 serial cable offers stable signal transmission and good resistance to EMI/RFI interference. It supports standard RS232 communication parameters including baud rates up to 115200bps, with compatibility for both low-speed configuration and general serial data transfer.

It is widely used for network device console access, industrial equipment debugging, PLC programming, CNC machine tool data exchange, POS terminal connection, serial printer communication and laboratory test system wiring. The cable is plug-and-play with standard RS232 ports and does not require additional drivers when used with a compatible serial port or USB-to-RS232 adapter.

Standard lengths of 1m, 1.5m and 3m are available from stock. Custom cable length, wire gauge, jacket color, connector type and private-label packaging are supported for bulk OEM orders.
