The Siemens 6ES7922-5BJ00-0AB0 is a pre-wired front connector for the SIMATIC S7-1500 system, carrying 20 single cores (H05V-K, 0.5 mm²) terminated at screw-type terminals on the enclosure end. It mates with the 40-pole connector base 6ES7592-1AM00-0XB0 and runs 8 m to the field device — a common length for routing from the cabinet backplane to a junction box or marshalling panel. Rated at 24 V with a maximum of 30 V, this assembly is sized for the standard S7-1500 digital I/O module signal levels. The 0.5 mm² conductor cross-section handles the typical 0.5 A per channel load without excessive voltage drop over the 8 m run.
This connector is designed exclusively for SIMATIC S7-1500 digital I/O modules — not for analog signal transmission. The 20 numbered cores (1 through 20) map directly to the module's channel terminals, so the wiring scheme is predictable: core 1 to channel 0, core 2 to channel 1, and so on. The blue PVC sheath (RAL 5010) and 2.2 mm outer diameter per core make bundle identification straightforward during panel wiring. Screw-type terminals on the module end accept the pre-stripped cores without ferrule crimping, which saves assembly time compared to spring-cage variants. The 40-pole connector body snaps into the module front, and the cable exits downward — plan for at least 100 mm clearance below the module row for the bend radius.
