InLine Serial Cable DB9F to DB25M S-19255A 0.33m

This InLine Serial Cable DB9F to DB25M S-19255A 0.33m is a short, shielded connection cable designed for serial data communication between devices with 9‑pin female and 25‑pin male D‑sub ports. The moulded plugs provide strain relief and consistent pin alignment while the compact 0.33 m length makes the cable suitable for installations with limited space. The neutral grey jacket blends into office, industrial or lab environments and the cable supports reliable point‑to‑point RS‑232 style connections for configuration, data logging and device control tasks.

Advantages

The moulded DB9F and DB25M connectors reduce wear at the connector interface and help maintain a stable connection over repeated plug cycles. Short cable length minimises signal attenuation and clutter in dense setups. The cable’s construction provides mechanical protection and keeps pin alignment consistent, which simplifies setup and reduces troubleshooting related to poor connections.

Suitable for

• Connecting legacy serial equipment such as modems, printers and industrial controllers
• Point‑to‑point RS‑232 communications for configuration and diagnostics
• Short runs in rack, bench or workstation environments where space is limited

Key specifications

• Connector A: 9‑pin D‑sub female (DB9F)
• Connector B: 25‑pin D‑sub male (DB25M)
• Length: 0.33 metres
• Jacket colour: grey
• Connector style: moulded plugs with strain relief

How to use

Align the keyed D‑sub connectors with the device ports and insert straight to avoid bending pins. Securely fasten any screws on the DB25M connector if the equipment provides thumbscrews or cage nuts to maintain a stable mechanical connection. Use the cable for direct serial links between a host and a peripheral; verify baud rate, parity and flow control settings on both devices to ensure communication parameters match before starting data transfer.

Usage recommendations

For optimal reliability keep the cable length as short as required for the installation, avoid sharp bends and excessive twisting, and route the cable away from high‑voltage or high‑frequency sources to reduce interference. Inspect the moulded connectors periodically for damage and replace the cable if pins are bent or the moulding is cracked.
