Serial cable DELOCK 84539, D‑Sub 25‑pin to D‑Sub 25‑pin, beige, 20 m

DELOCK 84539 is a 20 m beige serial cable with D‑Sub 25‑pin connectors on both ends, designed for RS‑232 and other legacy serial interfaces that use a 25‑pin D‑Sub connector. The cable offers a long, wired connection suitable for linking industrial controllers, networking equipment, printers or serial consoles where an extended reach is required without signal repeaters. Its neutral beige jacket and standard D‑Sub 25‑pin terminations ensure compatibility with equipment that retains the full 25‑pin serial pinout.

Advantages

This serial cable provides a straightforward, passive connection for devices using a 25‑pin D‑Sub interface, minimizing the need for adapters or custom wiring. The 20 m length supports installations where devices are spaced far apart, avoiding intermediate active components. Standard, rugged D‑Sub 25‑pin housings on both ends simplify mating with compatible ports and support stable mechanical contact in fixed installations.

Suitable for

• Connecting RS‑232 industrial controllers and PLCs to operator panels or PCs
• Linking legacy networking equipment and serial consoles during configuration and maintenance
• Wiring serial printers and peripheral devices that use a 25‑pin D‑Sub interface
• Temporary or permanent cable runs in workshops, server rooms, or production lines

Key specifications

• Connector type: D‑Sub 25‑pin to D‑Sub 25‑pin
• Cable length: 20 m
• Cable colour: beige
• Interface compatibility: RS‑232 and other 25‑pin D‑Sub serial implementations
• Cable construction: shielded multi‑core cable for serial signal transmission (standard passive wiring)

How to use

Connect each D‑Sub 25‑pin connector to the corresponding 25‑pin serial port on the devices to be linked, ensuring secure seating and screw fastening where applicable. Route the cable to avoid sharp bends, high‑voltage lines or sources of electromagnetic interference that could affect serial communication. For long runs, verify signal integrity and correct pin mapping on both devices; no active repeaters are required for standard RS‑232 signalling within typical device tolerances.

Usage recommendations

For reliable operation, keep the cable away from heavy power cabling and motors to reduce interference. Confirm that both devices support the full 25‑pin D‑Sub wiring or adapt pinouts as needed before installation.
