Microconnect SCSEHN3B serial cable Black 3 m DB9 M DB9 F

The Microconnect SCSEHN3B is a 3 m serial cable with DB9 male to DB9 female connectors designed for reliable RS-232 style communication between devices. The cable is RoHS certified and supplied in a black finish. With a lightweight construction and standard DB9 pinout it is intended for connecting serial peripherals, industrial controllers, legacy equipment and other devices that use a DB9 serial interface.

Advantages

The cable offers a straightforward DB9 M to DB9 F configuration that matches common serial ports and reduces the need for adapters. Its 3 metre length provides flexibility in equipment placement while keeping signal paths direct. RoHS certification confirms compliance with environmental restrictions on hazardous substances. The slim, lightweight design and black exterior simplify routing and integration into existing installations without adding significant bulk.

Suitable for

• Connecting PCs or laptops with DB9 serial ports to serial peripherals
• Linking industrial controllers, PLCs or instrumentation with RS-232 ports
• Interfacing legacy hardware such as modems, label printers or barcode scanners
• Temporary or permanent cabling where a 3 m reach is required

Key specifications

• Connector type: DB9 male to DB9 female
• Length: 3 m
• Weight: 58 g
• Color: black
• Compliance: RoHS certified
• Package dimensions: 275 mm x 159 mm x 31 mm

How to use

Ensure both devices are powered down or set to an appropriate state for hot-plugging if supported. Align the DB9 male connector with the DB9 female port on the device, insert gently and secure any retaining screws if present to ensure a reliable mechanical and electrical connection. Route the 3 m cable to avoid sharp bends and sources of strong electromagnetic interference. After connection, power on the devices and confirm serial communication parameters (baud rate, parity, stop bits) match on both ends.

Recommendations

For stable data transfer, use the cable in environments within specified equipment tolerances and avoid running it parallel to high-voltage power lines. If extended shielding or noise protection is required, consider using additional ferrite cores or shielded routing. Verify device settings and, when practical, secure connector screws to prevent accidental disconnection.
