The Siemens 6ES7922-4BF00-0AD0 is a 48-pole front connector with 46 single cores, purpose-built for SIMATIC S7-400 MS/MSP/MR units (mating with 6ES7492-1AL00-0AA0). Screw-type terminals on the enclosure side, 5 m of H05V-K cable, each core 0.5 mm², numbered 3 to 48. Rated 24 V, max 30 V. This is the cable-assembly version — not a bare header — so you're wiring straight into the I/O module's termination without a separate breakout board.
The 48 poles (46 used channels) map directly to the S7-400 module's I/O terminals — one core per channel, no sharing. Screw-type terminal on the enclosure side means you land field wiring with a standard screwdriver, no special tooling. 5 m cable gives enough reach from the rack to the cabinet door or a mid-panel junction point. The 0.5 mm² cross-section is fine for digital signals at 24 V; if you're running 24 VDC sensors or valve solenoids, this handles the current. Not rated for analog signal transmission — digital I/O only.
