Products Description

This product features a male-to-male configuration with a 45° right-angle design (viewed from the front of the connector, the cable exits to the right). The pin arrangement consists of 5 pins on the top row and 4 pins on the bottom, specifically optimized for extending serial connections within confined spaces. The internal wiring utilizes 28 AWG stranded tinned copper conductors, paired with aluminum foil shielding and a tinned copper braided mesh to effectively suppress EMI/RFI interference, thereby ensuring stable data transmission at baud rates ranging from 9600 bps to 115,200 bps.

It employs a full-pin, 1:1 straight-through wiring scheme (pins 1 through 9 connected directly), ensuring compatibility with standard RS232 serial communication protocols, and has successfully passed EMI compliance testing. This cable is suitable for applications requiring the extension of DB9 serial signals-such as industrial PCs, router consoles, and POS terminals-and is particularly well-suited for installation in tight locations where traditional straight connectors cannot be accommodated, such as along cabinet sidewalls or on the rear panels of equipment.

Purchase Advisory

Important Tips：

This product features a male-to-male configuration with a 45° right-angle design. It utilizes a right-side cable exit orientation, with a fixed pin arrangement where the 4-pin row is positioned above the 5-pin row.

Please note that the orientation of 45° DB9 connectors is not universally interchangeable. Before purchasing, you must verify the orientation of your device's interface, the required cable exit direction, the vertical arrangement of the pins, and the necessary connector gender (Male-to-Male).

If the orientation does not match, proper installation may be impossible, or the connector may physically interfere with the device's structure. Please ensure you carefully verify these details before making your selection.

FAQ

Q: How is the cable exit direction defined for this 45° right-angle extension cable?

A: The term "45° Right-Angle" refers to the cable exiting from the right side of the connector when viewed from the front of the interface (specifically, a 45° bend to the left resulting in a right-side cable exit). Combined with a pin configuration where "5 pins are at the top and 4 pins are at the bottom," this design is ideal for cable routing in confined spaces with specific directional requirements.

Q: If I accidentally purchase the wrong angle, can I simply twist the cable to make it fit?

A: No. The 45° angled head is permanently fixed via injection molding; attempting to forcibly twist it will damage the connector. Before purchasing, please be sure to verify the pin orientation (top/bottom placement), the required cable exit direction, and whether a male-to-male interface is indeed necessary for your device.

Q: Does the "5 pins at the top, 4 pins at the bottom" design imply that the alignment notch on the DB9 housing is also located at the top?

A: Yes. A standard DB9 male connector housing features a trapezoidal alignment protrusion (a "D-shaped" notch). On this product, when the 5-pin row is positioned at the top, this alignment notch is also located at the top. Consequently, for proper insertion into a device's female port, the female port's corresponding D-shaped notch must also be oriented upwards. If your device's female port is installed with a 180° rotation (meaning the 5-pin slot is at the bottom), this product cannot be inserted.

Q: Will the connector come loose if used in a high-vibration environment?

A: A: The connector housing on this product features threaded locking holes (4-40 UNC) on both sides. When fastened to the corresponding screw posts on your device, this provides vibration resistance and prevents accidental disconnection. If your device lacks screw posts, you can utilize the locking slots to wrap electrical tape around the connector for additional reinforcement. Once secured, the cable is suitable for use in environments such as vehicles, vibration test platforms, and similar settings.

Drawing

Please carefully examine the device interface diagrams or actual product photos to verify the DB9 pin orientation (5 pins on top, 4 pins on the bottom), the 45° right-angle cable exit direction, and the male-to-male connector configuration. This ensures that you avoid purchasing the wrong item-and subsequently being unable to install it-due to discrepancies in these specific details.
