ACT 20m Serial RS-232 Straight-Through Cable DB9 Plug to Socket AK2322

In industrial control rooms and legacy IT closets, technicians often need to bridge a 20-meter gap between a server’s DB9 male port and a peripheral with a DB9 female socket. This ACT AK2322 serial cable solves that problem with a straight-through, 1:1 pin configuration that preserves signal integrity over long runs. The 9-pin D-sub male connector plugs directly into your PC, while the female end accepts a modem, printer, or any RS-232 device. Its robust construction resists wear from frequent reconnection, making it a dependable link for point-of-sale terminals, CNC machines, and network switches.

Why choose it

The 20-meter length gives you flexibility to position equipment far from the host without signal boosters. Straight-through wiring ensures that transmit and receive lines align correctly, eliminating the need for null-modem adapters in most direct connections. The metal-shell connectors provide shielding against electromagnetic interference, which is critical in electrically noisy environments like factory floors. ACT’s manufacturing consistency means every pin is soldered and tested, so you can trust this cable for mission-critical data transfers.

Ideal use cases

• Connecting a PC to a serial printer or plotter across a room
• Extending a console connection to a network switch or router
• Linking industrial sensors or PLCs to a central controller
• Setting up a point-of-sale system with a barcode scanner
• Bridging legacy lab instruments to a modern computer

Good to know

The cable supports standard RS-232 signaling up to typical baud rates, though maximum distance may vary with speed. For best performance, avoid sharp bends and keep the cable away from high-voltage lines. The DB9 connectors are compatible with any standard 9-pin serial port, and the male-to-female gender combination covers the most common extension scenario. If you need a longer run, consider a signal booster or lower baud rate.
