It mates to the 6ES7392-1AJ00-0AA0 connector housing on the module face, so you pull the cable into the cabinet and land the 20 individually numbered cores (AWG 20, 0.5 mm²) at your terminal strip or junction box. The screw terminals on the enclosure side accept field wiring; the cable side is factory-terminated. Rated 24 V with a maximum of 30 V, it's sized for the 24 VDC digital signals typical of S7-300 input and output cards. The 30 V maximum and 24 V rated value match the standard S7-300 digital I/O bus voltage — 24 VDC nominal, with headroom up to 30 V for transient tolerance. The 20 poles and 20 channels cover a full 20-point digital module; if you're wiring a 16-channel card you'll have four unused cores, but the connector is the same physical part. The 3.2 m cable length is enough to reach a nearby DIN-rail terminal block inside a standard 800 mm enclosure; for longer runs you'd need an extension or a junction box. Core numbering runs 1 to 20 in white on the adapter contacts, which matches the S7-300 module pinout, so you can land each signal without a separate wiring diagram. ## Cable construction and environmental limits The cable sheath is blue PVC (RAL 5010), outer diameter 2.2 mm per bundled single core, with a multi-conductor braid design. The PVC jacket is rated for general industrial environments — not oil-resistant or continuous-flex rated, so avoid routing through cable tracks or areas with coolant mist. The cable transmits digital signals only; it is not suitable for analog signal transmission.","metaTitle":"Siemens 6ES7922-3BD20-0UB0 Front Connector, 20-Pole, 3.2m, S","metaDescription":"Siemens 6ES7922-3BD20-0UB0 front connector with 20 single cores, 3.2 m length, screw-type terminals for SIMATIC S7-300 digital I/O modules.
