Slot bracket cable Intos DB25 female to 26-pin header, 0.34 m, silver

The Intos slot bracket cable provides an external DB25 female Sub-D connector mounted on a silver-coloured metal bracket and terminated with a 26-pin IDC header on a 0.34 m cable. It is intended to be fitted into a standard PC expansion slot to expose an internal 26-pin parallel/IO header as a 25-pin external connector. The assembly is lightweight (48 g) and supplied as a single unit in bulk packaging. The cable supports typical parallel, serial-adapted or custom I/O wiring schemes when matched to a compatible motherboard header or adapter board.

Advantages

The metal slot bracket offers a secure and standardized external mounting for the DB25 female connector while the short 0.34 m cable keeps internal routing tidy. The 26-pin IDC termination provides a direct connection to compatible motherboard headers or daughter boards without the need for soldering. The product’s straightforward pin mapping enables predictable signal routing for parallel port implementations or custom I/O arrangements. Its compact design and light weight simplify installation in standard desktop PC cases.

Suitable for

• Connecting an internal 26-pin parallel or I/O header to an external DB25 female port
• Providing an external interface for legacy parallel devices or custom I/O modules
• Integration with adapter boards or cable assemblies that follow the specified IDC–Sub‑D pinout
• Use in desktop PC expansion slots where a rear-panel DB25 connector is required

Key specifications

• Cable length: 0.34 m
• External connector: DB25 female (25-pin Sub-D)
• Internal connector: 26-pin IDC (ribbon-type header)
• Bracket material and colour: silver-coloured metal
• Weight: approximately 48 g
• Pin mapping (IDC to Sub-D): 1→1, 2→14, 3→2, 4→15, 5→3, 6→16, 7→4, 8→17, 9→5, 10→18, 11→6, 12→19, 13→7, 14→20, 15→8, 16→21, 17→9, 18→22, 19→10, 20→23, 21→11, 22→24, 23→12, 24→25, 25→13; pin 26 on the IDC is not connected

How to use

Power off the PC and remove the case cover. Insert the metal bracket into an available rear expansion slot and secure it to the chassis using the slot screw. Align the 26-pin IDC header with the corresponding internal header on the motherboard or adapter board, ensuring correct orientation according to the board’s silk-screen or documentation, then press the IDC connector onto the header until fully seated. Replace the case cover and power on the system. Verify the external DB25 connector is recognized or that signals are present according to the connected device and the host configuration.

Usage recommendations

Confirm the motherboard or adapter header pinout before connecting to avoid damage to devices. Use this cable for low-frequency parallel or custom I/O signals; avoid relying on it for high-speed differential interfaces. If signal integrity or shielding is critical, consider using a shielded cable or additional ground connections and keep the cable length short and routed away from high-power or high-frequency sources.
