Serial Cable EFB Elektronik EK125.3 Beige 3m D-Sub 25-pin to 9-pin

The EFB Elektronik EK125.3 is a 3-meter shielded serial cable with a 25-pin D-Sub plug on one end and a 9-pin D-Sub plug on the other. The cable is finished in beige and is intended for reliable serial data connections between devices that use D-Sub connectors.

Advantages

Shielding reduces electromagnetic interference for more stable data transmission. Factory-mounted D-Sub connectors ensure correct pin alignment and reduce installation time. The 3 m length provides flexibility for typical desktop, rack or equipment-room setups while maintaining signal integrity.

Suitable for

• Connecting RS-232 devices with 25-pin and 9-pin D-Sub interfaces
• Serial communication between PCs, industrial controllers and measurement equipment
• Use in office, laboratory or workshop environments where a medium-length serial connection is required

Key specifications

• Cable type: shielded serial cable
• Connector A: D-Sub 25-pin (male/female as per product plug configuration)
• Connector B: D-Sub 9-pin (male/female as per product plug configuration)
• Length: 3 m
• Colour: beige

How to use

Connect the D-Sub 25-pin end to the device with a matching 25-pin serial port and the D-Sub 9-pin end to the device with a 9-pin serial port. Ensure connectors are firmly seated and fasten any connector screws to secure the connection. Configure serial communication parameters (baud rate, parity, data bits, stop bits) in the connected devices to match for proper data exchange.

Recommendations

For best results, route the cable away from heavy power lines and motors to minimize interference. If communication errors occur, check connector seating and verify that serial port settings on both devices match.
