Siemens 6ES5727-2CB00 Connecting Cable

The Siemens 6ES5727-2CB00 connecting cable links SIMATIC S5 processors to external operator panels. This cable carries both data signals and power supply voltage for connected devices. It connects directly to the AS511 interface on S5 CPUs. You can use this cable as a direct replacement for worn or damaged units.

Detailed Technical Specifications

The Siemens 6ES5727-2CB00 connecting cable measures 2.5 meters in total length. Its outer diameter reaches 6.5 mm across the shielding jacket. The cable weighs approximately 0.18 kilograms for easy handling. This assembly uses flexible PVC insulation for repeated bending.

Key hardware parameters include:

Application and Installation

The Siemens 6ES5727-2CB00 connecting cable links S5 CPUs to OP text displays. This cable also connects to PG programming devices for upload and download operations. It carries both the AS511 data signal and 24 V power. Consequently, the connected device needs no separate power supply.

Signal Integrity and Reliability

This cable rejects electromagnetic interference from motors and drives. Its dual shielding reduces crosstalk between adjacent signal pairs. The Siemens 6ES5727-2CB00 includes a drain wire for chassis grounding. Therefore, you achieve reliable communication in noisy industrial environments.

Always power down both devices before connecting or disconnecting this cable. Tighten the locking screws on both connectors securely. The cable features a flexible jacket for tight bend radius installations. Furthermore, the molded strain relief prevents wire breakage at the connector entry points.
