Serial Cable EFB Elektronik EK137.1 Beige 1m D-Sub 25

The EFB Elektronik EK137.1 Beige 1m D-Sub 25 serial cable is designed to provide a reliable connection between devices that use a 25-pin D-Sub (DB-25) serial interface. With a one-meter length and a neutral beige jacket, the cable suits desktop and rack environments where a compact, unobtrusive link is required. The construction focuses on consistent signal transmission and mechanical durability to support routine data communication tasks.

Advantages

This serial cable offers stable data transfer for RS-232-compatible equipment using a full-size D-Sub 25 connector. The one-meter length balances flexibility and tidiness near workstations or equipment racks. The beige outer jacket blends with many office and industrial settings while providing basic protection against wear. Durable connector housings and secure mating reduce the risk of intermittent connections during operation.

Suitable for

• Connecting legacy serial printers, terminals and modems with D-Sub 25 ports
• Linking industrial controllers, measurement devices or PLCs that use 25-pin serial interfaces
• Point-of-sale systems and laboratory equipment requiring DB‑25 connections
• Service and maintenance tasks where a short, reliable serial link is needed

Key specifications

• Cable length: 1 meter
• Connector type: 25-pin D-Sub (DB-25) at each end
• Color: beige outer jacket
• Conductor arrangement: multi-core serial cable suitable for RS-232 signal levels
• Typical use: point-to-point serial communications

How to use

Connect each end of the cable to the corresponding DB‑25 serial ports on the two devices, ensuring correct orientation and secure seating of the connectors. Tighten any captive screws or fastening mechanisms to maintain a stable physical and electrical connection. After connection, configure the serial parameters (baud rate, parity, data bits, stop bits and flow control) on both devices to match, then verify communication using the appropriate terminal software or device diagnostics.

Recommendations

For consistent performance, avoid routing the cable alongside high-voltage power lines or heavy electromagnetic noise sources. Use the shortest practical length to reduce potential signal degradation and check connector screws periodically to prevent looseness. When installing in industrial environments, ensure the cable is protected from sharp edges and excessive bending to extend service life.
