The Siemens 6ES7922-4BD20-0AE0 is a 48-pole front connector for SIMATIC S7-400 I/O modules, delivering 46 individually numbered single cores (0.5 mm², H05V-K) terminated via crimp connections at the module end. The 3.2 m cable length gives enough reach from the rack to a panel-side junction point without excess coil — sized for standard 19-inch cabinet depths. Rated at 24 V with a maximum of 30 V, this connector handles the signal-level voltages typical of S7-400 digital I/O cards. The 46 channels match the channel count on 48-point I/O modules (two pins are keying/mechanical).
Integration with S7-400 I/O
This connector mates with the 48-pin receptacle 6ES7492-1CL00-0AA0 on S7-400 digital input/output modules. The crimp termination suits panel builders who pre-wire cables on a bench, then snap the connector onto the module during rack assembly — no screw terminals to torque inside a tight cabinet. Cores are numbered consecutively from 3 to 48 in the white adapter contact, matching the module's pin assignment. The blue PVC sheath (RAL 5010) and 2.2 mm outer diameter per core keep wire identification clear during troubleshooting. Operating temperature range of 0 to 60 °C covers most control-room environments; storage range of -30 to +70 °C allows for unheated warehouses during project staging.
The 6ES7922-4BD20-0AE0 carries a mature lifecycle status — still in the Siemens catalog for new installations and spares, not flagged for phase-out.
