The Siemens 6ES7922-4BF00-0AE0 is a front connector with single cores for SIMATIC S7-400 systems, specifically the 48-pole strip used with MS, MSP, and MR units (6ES7492-1CL00-0AA0). It carries 46 single cores of 0.5 mm² cross-section, each H05V-K PVC-insulated, terminated with crimp connections at the module end and numbered consecutively from 3 to 48 for clear field wiring identification.
Rated for 24 V nominal with a maximum of 30 V, this connector is designed for digital signal transmission on digital I/O modules — not for analog signals. The 5 m cable length gives enough reach to route from the rack to a field terminal strip inside a standard enclosure, with the blue sheath and RAL 5010 color making it visually distinct from power cables during panel troubleshooting.
The connector uses crimp-type terminals, so you will need the appropriate crimp tool for 0.5 mm² conductors. The 48-pole header on the module side mates with the 6ES7492-1AL00-0AA0 connector body.
