E3321 Serial Cable DB9M  DB9M

Reliable Data Communication: DB9 Male to DB9 Male Serial Cable (1.4 / 3 / 5 Meter) 

Ensure stable and secure data transmission with our premium DB9 Male to DB9 Male Serial Cable. Also known as an RS232 cable, this connector is the industry standard for connecting various serial peripherals to computers, PLC systems, and industrial machinery.

Key Performance Features:

• Secure Thumbscrew Connection: Each connector is equipped with integrated thumbscrews, ensuring a vibration-proof and secure connection that won't accidentally pull loose during critical data transfers.

• Fully Molded Strain Relief: The connectors are fully molded to the cable jacket, providing superior durability and protecting the internal wiring from damage caused by bending or pulling.

• High-Quality Shielding: Constructed with internal shielding to minimize EMI/RFI interference, ensuring clean signal integrity over longer distances.

• Versatile Compatibility: Designed for use with legacy hardware, industrial controllers, and modern serial-to-USB adapters.

Technical Specs 

• Connector A: DB9 Male (9-Pin).

• Connector B: DB9 Male (9-Pin).

• Available Lengths: 1.4 / 3 / 5 Meters.

• Wiring Configuration: Straight-through (Standard serial data link).

Typical Applications

• Industrial Automation: Connecting PLCs (Programmable Logic Controllers) to HMI panels or programming terminals.

• Networking Hardware: Serving as a console cable for older routers, switches, and server hardware.

• Legacy Peripherals: Connecting serial printers, barcode scanners, and laboratory equipment to PC systems.

• Scientific Equipment: Ideal for data logging from specialized scales, sensors, and meters that utilize the RS232 standard.

Top 3 Customer Questions & Concerns ‍

1. Is this a "Straight-through" or "Null Modem" cable?

   • This is a standard Straight-through DB9M to DB9M cable designed for general data links between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment).

2. Will this work with a USB to Serial adapter?

   • Yes! If your laptop lacks a native serial port, you can use this cable as an extension for your USB-to-DB9 adapter to reach your equipment.

3. Can I use the 5-meter version for high-speed data?

   • RS232 is inherently a lower-speed communication standard compared to USB. However, our 5M cable is shielded to maintain signal quality at standard baud rates over the full length.
