It carries 40 conductors on a 40-pole IDC connector at one end and a 50-pole connector at the module end, routing 32 digital I/O signals between the backplane and the field termination. Rated at 24 V with a maximum of 60 V, the cable is sized for the signal levels typical of S7-1500 digital input and output cards. The 2 m length covers the span from the I/O module to a nearby connection module inside the same cabinet. ## Cable construction and handling Each conductor is 0.14 mm², PVC-jacketed, with an overall sheath diameter of 10.3 mm. The cable is unshielded — fine for digital signals inside a grounded steel enclosure, but not suitable for analog signal paths or runs near variable-frequency drives without additional screening. Both ends terminate in connector strips (IDC on the cable side, connector strip on the enclosure side), so the cable drops in without field wiring. The 40-pole IDC connector mates to the I/O module; the 50-pole connector attaches to the connection module. The 2 m fixed length and 40-pole IDC interface are specific to the S7-1500 64 I/O architecture — verify the connection module pole count (50 poles at the module end) before committing the line.","metaTitle":"Siemens 6ES7923-5BC00-0GB0 Pre-assembled Round Cable, 2 m, 4","metaDescription":"Pre-assembled round cable for SIMATIC S7-1500, 2 m, 40-pole IDC connector, 32 channels, rated 24 V / max 60 V.
