Wire Connector DeLOCK 66321 1 x Serial Sub-D 9 1 x 9 Pin Black Green Silver Yellow

The DeLOCK 66321 wire connector is a compact terminal block adapter designed to connect bare wires to a 9‑pin Sub‑D (Serial) interface. The adapter combines a single male Sub‑D 9 housing with screw terminal contacts and measures approximately 31 mm (W) × 36 mm (D) × 17 mm (H). Its multicolour housing—black, green, silver and yellow—helps identify connections and the unit is supplied in a polybag.

Advantages

The adapter allows direct connection of stripped wires without soldering, providing a fast and serviceable interface between cable conductors and a Sub‑D 9 serial connector. Its compact dimensions suit tight installations and the colour-coded housing assists wiring identification. The screw terminal design enables secure, reusable connections for testing, maintenance or prototype work.

Suitable for (tasks / use cases)

• Connecting bare wires to a Serial Sub‑D 9 port
• Prototyping and development work with serial interfaces
• Industrial and hobby applications such as model railways
• Field testing and temporary wiring where soldering is not desirable

How to use

Strip the insulation from each wire to the appropriate length, insert the conductor into the corresponding screw terminal and tighten the screw to secure the connection. Align the Sub‑D male connector with the mating serial port and fasten as needed. For removal, loosen the screws and withdraw the conductors. Observe correct pin assignment for your serial application when wiring.

Recommendations

Use wires of suitable gauge for the screw terminals and ensure screws are tightened to avoid intermittent contact. Avoid exposing the connector to high moisture or corrosive environments; for permanent installations consider a sealed or soldered connection.
