The Siemens 6ES7922-5BC50-0AC0 is a pre-wired front connector for the SIMATIC S7-1500 platform — specifically the 40-pole variant that mates with the 6ES7592-1AM00-0XB0 connector base. It comes as 40 individual single cores (H05V-K, 0.5 mm²), each numbered consecutively from 1 to 40 with a white adapter contact marking, bundled in a blue PVC sheath with a 2.2 mm outer diameter per core. The screw-type termination on the enclosure side means you land each wire under a screw clamp — no special tooling beyond a standard screwdriver. Rated at 24 V with a maximum of 30 V, this connector is built for the signal-level voltages typical of S7-1500 digital I/O modules — not power distribution. The 2.5 m cable length gives enough reach to route through a swing-panel hinge or across a backplane without a junction box. Operating temperature range is 0 to 60 °C; storage from -30 to +70 °C.
This connector is sized for S7-1500 digital I/O modules — both input and output cards. It's not rated for analog signal transmission, so keep it on discrete 24 VDC field wiring. The 40 channels match the density of a standard 40-pin S7-1500 module; you get one numbered core per channel, which simplifies troubleshooting and re-termination during commissioning. The RAL 5010 blue sheath is the standard Siemens I/O cable color — easy to spot in a crowded cabinet.
