The Siemens 6ES7922-5CB00-0HB0 is a pre-assembled front connector for the SIMATIC S7-1500 system, terminated with 20 single cores on a 40-pole screw-type terminal block. The cable is 10 m long, each core is 0.5 mm², and the sheath is halogen-free H05Z-K in blue (RAL 5010). It is designed specifically for digital I/O modules — it is not intended for analog signal transmission.
Rated at 24 V with a maximum of 30 V, this connector handles the standard 24 VDC control voltage of the S7-1500 backplane and I/O modules. The 40-pole connector (6ES7592-1AM00-0XB0) mates with the module's front interface; the 20 cores are numbered consecutively 1–20, with the white adapter contact marking the core number — so you get one signal per core, not a shared return. The screw-type terminal on the enclosure side accepts 0.5 mm² wire, which is the rated cross-section; no need to strip or ferrule differently than the factory termination.
This front connector is the wiring interface between the S7-1500 digital I/O module and the field devices — sensors, actuators, pushbuttons, indicator lights. The 10 m cable length gives enough reach to route to a nearby junction box or terminal strip inside the panel. The halogen-free sheath (H05Z-K) matters for panels that must meet fire-safety requirements in public buildings or process plants.
