The Siemens 6ES7923-5BC50-0DB0 is a pre-assembled round cable shielded for the SIMATIC S7-1500 system, connecting a front connector module to a connection module via 50-pole IDC connectors at both ends. Rated at 24 V with a maximum of 60 V, it carries 32 channels for both digital and analog I/O signals — meaning one cable handles the full signal set for a mixed I/O module without separate analog and digital runs. The 2.5 m length and 11 mm outer diameter with a braided shield make it a clean drop-in for a standard S7-1500 cabinet layout; the PVC sheath and black jacket match the usual panel aesthetic.
The 50-conductor, 0.14 mm² cross-section cable terminates at both ends with IDC connectors — one mates to the cable-side front connector module, the other to the connection module. No field wiring or stripping needed; it's a factory-terminated assembly. The braided shield covers the full 2.5 m run, which keeps common-mode noise off analog signals in mixed I/O cabinets. Shield grounding at the panel end only is the standard practice here. Rated for 0 to 60 °C during operation and -30 to +70 °C storage, so it handles the thermal range inside a ventilated enclosure without derating concerns.
