The Siemens 6ES7922-5BG50-0UC0 is a 40-pole front connector with a 6.5 m multi-norm braided cable, terminated in single cores with screw-type terminals, designed for SIMATIC S7-1500 digital I/O modules. It mates with the 6ES7592-1AM00-0XB0 connector on the module side. Rated for 24 V nominal, 30 V maximum, with 0.5 mm² conductors.
The 40 poles match the full complement of an S7-1500 digital I/O module (e.g., 32 DI + 8 spare or 16 DO + 24 signal). The 6.5 m cable length gives enough reach to route from the module in a cabinet to a junction box or terminal strip without a splice. Screw-type terminals on the field end accept 0.5 mm² cores — standard for 24 V control signals — and the cores are numbered consecutively 1 to 40, which simplifies wiring verification against the I/O map.
