The Siemens 6ES7922-3BF00-0AB0 is a 20-pole front connector with single cores, purpose-built for SIMATIC S7-300 digital I/O modules. It terminates at a screw-type terminal block on the enclosure side and runs 5 m of bundled single cores (0.5 mm² each, H05V-K, blue PVC sheath) to the field wiring. The connector mates with the 6ES7392-1AJ00-0AA0 receptacle on the module face. Rated for 24 V (maximum 30 V), it handles the signal levels typical of S7-300 digital inputs and outputs — no analog signal transmission. The 20 cores are numbered consecutively 1 to 20, with a white adapter marking the core number, so panel wiring matches the module pinout without guesswork.
Integration notes
The screw-type terminal accepts 0.5 mm² conductors (the supplied cores are already 0.5 mm² H05V-K). Operating temperature range is 0 to 60 °C; storage from -30 to +70 °C. The blue sheath (RAL 5010) and 2.2 mm outer diameter per core make it easy to identify and route in a crowded cabinet.
