Product details

What this connector does in an S7-400 rack

The Siemens 6ES7922-4BD20-5AD0 is a 48-pole front connector for SIMATIC S7-400 digital I/O modules, delivering 46 signal cores via a 3.2 m pre-wired cable with screw-type terminals on the enclosure end.

Wiring and signal routing

Each of the 46 single cores is 0.5 mm² H05V-K wire, numbered consecutively from 3 to 48, with a blue PVC sheath (RAL 5010). The 48th pole on the connector is the 48th core; the first two positions are unused in this variant. Rated for 24 V nominal with a maximum of 30 V, this connector is suited for digital I/O signals — not analog transmission. The screw terminals accept field wiring on the enclosure side.

This front connector is in mature production. No official replacement or cross-reference is listed — confirm the BOM position count and mating module before committing.

Frequently asked questions

Is 6ES7922-4BD20-5AD0 compatible with SIMATIC S7-400?

Yes, it is designed for SIMATIC S7-400 digital I/O modules, specifically the 48-pole strip for MS/MSP/MR units (6ES7492-1AL00-0AA0). It handles digital signals only — not analog.

What is the difference between 6ES7922-4BD20-5AD0 and 6ES7922-4BD20-5AA0?

The 6ES7922-4BD20-5AD0 has a 3.2 m cable length, while the 5AA0 variant typically has a shorter cable. Both are 48-pole screw-type front connectors for S7-400. Confirm the cable length needed for your cabinet layout.

How can I order the Siemens 6ES7922-4BD20-5AD0 front connector?

This part is in mature production and sourced to order against your BOM quantity.
