D-Sub 9 M/M-connector EFB Elektronik EB410

The EFB Elektronik D-Sub 9 M/M Connector (EB410) is a compact gender changer with two 9-pin D-Sub (DB9) male connectors. It enables conversion between compatible serial and parallel D-Sub plugs, providing a space-saving solution for connecting devices with D-Sub interfaces. Constructed with a metallic housing, this adapter is intended for reliable data transmission and repeated use in electronics and communication setups.

Advantages

This mini gender changer offers a compact footprint while preserving signal integrity for standard RS-232 and other D-Sub applications. Its metal construction increases mechanical durability and wear resistance. The simple M/M configuration allows direct coupling of two female-ended cables or ports without additional cables or adapters.

Suitable for

• Connecting two DB9 female cables or ports
• Adapting serial RS-232 devices with D-Sub interfaces
• Temporary patching in electronics repair or testing
• Space-limited installations requiring a compact gender changer

Key specifications

• Model: EFB Elektronik EB410
• Connector type: 9-pin D-Sub (DB9) male to male
• Quantity of pins: 9 per connector
• Housing: metallic
• Applications: serial/parallel D-Sub connections (e.g., RS-232)

How to use

Align each DB9 male connector with the corresponding female D-Sub port or cable and push gently until secure. Ensure correct orientation to avoid bending pins. Use the adapter for direct connections between two female-ended cables or to bridge compatible ports on equipment. Do not force the connectors; if resistance is felt, check alignment and pin condition.

Recommendations

For reliable long-term use, avoid excessive mechanical stress on the adapter and secure connected cables to reduce strain on the DB9 pins and housing. Inspect contacts periodically for damage or corrosion and replace the adapter if any bent pins or degraded connections are detected.
