Serial Cable EFB Elektronik EK137.3 Beige 3m D-Sub 25

The EFB Elektronik EK137.3 Beige 3m D-Sub 25 serial cable is a 3-metre communication lead designed for devices with a D-Sub 25 interface. The cable delivers a straightforward wired connection for serial data transfer between peripherals, control units, and industrial equipment. Constructed with a D-Sub 25 connector on each end and a neutral beige jacket, it balances unobtrusive appearance with practical reach for desktop, rack, or machinery installations.

Advantages

The cable provides reliable serial signal transmission over a 3 m length with robust connector housings that maintain contact integrity under repeated insertions. Its standard D-Sub 25 interface ensures wide compatibility with legacy and industrial devices that use RS-232/parallel-style connections. The beige outer sheath offers resistance to everyday wear while blending into office and equipment environments.

Suitable for

• Connecting computers, printers, or terminals with D-Sub 25 ports
• Linking PLCs, HMIs, and other industrial control equipment
• Establishing point-to-point serial communications for device configuration or diagnostics
• Replacing or extending existing D-Sub 25 wiring in lab and workshop setups

Key specifications

• Cable length: 3 metres
• Connector type: D-Sub 25 (male/female configuration as per device requirements)
• Color: Beige jacket
• Construction: Shielded multi-core cable suitable for serial data signals
• Intended use: Serial/parallel D-Sub 25 connections for data and control signals

How to use

Identify the D-Sub 25 ports on the devices to be connected and align the connector shells with the port openings. Insert the connectors firmly and secure any thumbscrews or fastening hardware to ensure a stable electrical connection. Route the cable to avoid sharp bends and mechanical strain; allow service loops where necessary. For reliable communication, configure the connected devices to matching serial parameters (baud rate, parity, data bits, stop bits) if applicable.

Recommendations

For optimal performance, avoid running the cable in parallel with high-power AC lines to reduce electrical interference. Inspect connector contacts periodically and replace the cable if the jacket or connector shows signs of damage. When used in industrial environments, secure the cable to strain-relief points and maintain appropriate separation from sources of electromagnetic noise.
