The Siemens 6ES7922-3BD20-0AG0 is a 40-pole front connector with pre-terminated single cores, purpose-built for SIMATIC S7-300 digital I/O modules. It terminates the field wiring to the module via a crimp connection, delivering 40 individually numbered conductors (H05V-K, 0.5 mm²) in a 3.2 m blue PVC sheath. The connector mates with the S7-300 front-pin header (mating connector 6ES7392-1AM00-0AA0) and secures signal continuity from the backplane to the field device. Rated for 24 V nominal with a maximum of 30 V. Conductor cross-section is 0.5 mm² over a 3.2 m run.
The 40 single cores are numbered consecutively 1–40 via white adapter contacts. Crimp connection for 0.5 mm² conductors. Operating temperature range 0 to 60 °C; storage range -30 to +70 °C. The PVC sheath (H05V-K) is rated for fixed installation within control panels — not for continuous flexing or cable-track duty.
