## Long description

EFB Elektronik EK137.2 is a 2 m serial cable with a 25-pin D-Sub connector in beige, designed to connect devices that use a 25-pin D-Sub serial interface. The cable provides a reliable wired link for data transfer and control between compatible equipment, supporting common RS-232 and parallel-style connections used in industrial and office environments. Its 2 metre length balances reach and signal integrity for typical desk-to-device and short-run industrial installations.
Advantages
The cable features a standard male/female D-Sub 25 interface for compatibility with a wide range of legacy and industrial equipment. Constructed with shielding and durable insulation, it reduces interference and mechanical wear in everyday use. The neutral beige colour makes it unobtrusive in mixed-cabinet or office setups, while the fixed 2 m length simplifies routing and avoids excess cable management in many setups.
Suitable for
 Connecting industrial controllers, CNC machines and laboratory instruments with a 25-pin D-Sub serial port
 Linking legacy printers, plotters or parallel-interface devices that use D-Sub 25 connections
 Workstation to serial-device connections in offices, workshops and service areas
 Short-run signal and data connections inside equipment racks or between adjacent cabinets
Key specifications
 Cable length: 2 m
 Connector type: D-Sub 25 (25-pin)
 Connector colour: beige
 Signal standard: compatible with RS-232 and parallel-style D-Sub 25 interfaces
 Construction: shielded cable with insulated jacket for reduced interference
How to use
Connect the D-Sub 25 connector to the corresponding 25-pin port on each device, ensuring secure seating and, where present, fastening the connector screws to prevent accidental disconnection. Verify that both devices use compatible signal levels and pinouts (RS-232 or parallel-style) before powering equipment. Route the cable away from strong electromagnetic sources and sharp edges to preserve signal quality and cable integrity.
Usage recommendations
For stable communication, confirm device settings (baud rate, parity, handshaking) and inspect connectors periodically for bent pins or loose screws. Use the 2 m length for short-range connections; if longer runs are required consider signal repeaters or alternative interfaces. Avoid kinking the cable and keep it away from high-voltage lines to reduce noise and extend service life.
