The Siemens 6ES7923-3BF00-0HC0 is a shielded connection cable for the SIMATIC ET 200SP HA distributed I/O system. It runs 5 meters from a 37-pole D-sub connector to bare ends with wire end sleeves, labeled for 32 channels, using 0.34 mm² conductors.
What the ratings mean for fit
The 37-pole D-sub on one end and bare ends on the other mean this cable is meant to bridge the ET 200SP HA interface module to a field termination or junction box — you land the bare ends on your terminal block and the D-sub plugs into the I/O module. The 5 m length covers most cabinet-to-field runs without excess slack. The 0.34 mm² conductor cross-section (roughly 22 AWG) is sized for the signal-level currents on digital and analog I/O channels — not for power distribution. The wire end sleeves on the bare ends make for clean, reliable terminations on spring-cage or screw terminals.
