Unshielded connecting cable for SIMATIC S7-300/1500 between front connector module and connection module 16x0.14 mm2 with IDC connectors, length = 4.0 m The 16-pin round cable (unshielded) with a length of 4m represents the link between the front connector and connection module. This pre-assembled cable enables interference-free and safe signal flow. This means that even complex installations remain manageable and can be checked in the shortest possible time, which is particularly affordable for maintenance and extensions. This pre-assembled connecting cable is part of the fully modular connection of SIMATIC TOP connect for the fastest and safest system cabling. In addition to low wiring effort, sources of error in the cabling can be significantly reduced. Sensors and actuators from the periphery are connected to the connection modules of SIMATIC TOP connect and connected to the SIMATIC S7-1500 via a connecting cable and front connector module.
