## Summary description

The Tecline D-Sub 9p F/F connector features a durable blue and stainless steel design. It includes two D-Sub 9p connectors, ensuring reliable connections for various applications. Ideal for data transmission, this connector is built to withstand wear and tear, making it a dependable choice for both professional and personal use.

## Long description

The Tecline D-Sub 9p F/F Connector Tecline 50403 is a double female D-Sub adapter designed to join two 9-pin D-Sub (DB9) cables without altering signal wiring. The unit combines a blue plastic shell with stainless steel fastening elements to provide a compact, durable joiner suitable for serial data and control signal connections. Its two female D-Sub 9-pin ports enable straightforward extension or coupling of male-ended cable assemblies for RS-232, RS-485 and similar low-voltage communication lines where a standard DB9 interface is used.
Advantages
The connector's metal fastening hardware ensures secure mechanical contact and reliable alignment between connected cables while the molded blue housing resists everyday impacts and abrasion. Its passive, gender-changing adapter design requires no power or configuration, preserving pin mapping and signal integrity when linking two male DB9 connectors. The compact form factor minimizes added bulk inline and enables placement in tight installations.
Suitable for
 Extending or joining serial RS-232/RS-485/TTL DB9 cable runs
 Temporary field connections and quick equipment swaps
 Industrial control panels and test bench cabling
 Legacy computer and instrumentation interfaces
Key specifications
 Connector type: Female-to-female D-Sub 9-pin (DB9) adapter
 Number of ports: 2 female DB9 ports
 Housing material: blue molded plastic
 Fastening: stainless steel screws and thumbscrews for secure mating
 Function: passive passive gender adapter, preserves pin mapping

How to use
To use the Tecline D-Sub 9p F/F Connector, align the male DB9 plug on each cable with the female ports, then engage the fastening screws to secure the connection. Ensure the pins align correctly and avoid forcing connectors together to prevent bent pins. The adapter is intended for low-voltage signal connections; do not use it where power-carrying or high-voltage circuits are present without appropriate isolation. Remove the adapter by loosening the thumbscrews and gently separating the cable ends.
Usage recommendations
Use the adapter in dry, clean environments and inspect connectors periodically for bent pins or corrosion. For long-term or vibration-prone installations, verify screw tightness and consider strain relief on cable entries to reduce mechanical stress on the adapter and connected equipment.
