It runs 2 m long, carries 50 conductors at 0.14 mm² each, and terminates in IDC connectors — one 4 × 16-pole front connector module on the cable side and a 1 × 50-pole connection module on the enclosure side. Rated for 24 V nominal operation with a maximum rating of 60 V, it handles the signal levels typical of 24 VDC digital inputs and outputs without analog signal transmission. ## Integration into a SIMATIC panel This cable bridges the gap between the front connector on an S7-300 or S7-1500 digital I/O module and a 50-pole connection module mounted on the enclosure wall or DIN rail. The round PVC sheath (outer diameter 10.3 mm) is unshielded — fine for digital signals inside a steel enclosure, but not for analog or noise-sensitive circuits. The IDC connectors on both ends mean termination is factory-set; no field stripping or crimping. The 2 m length gives enough slack to route through a cable duct or wireway without coiling excess. The 24 V rated value matches the standard control voltage for SIMATIC S7-300 and S7-1500 digital I/O modules — 24 VDC is the rail voltage these modules expect on their input circuits and output drivers. The 60 V maximum means the cable insulation and connector spacing are rated for that ceiling, so it won't break down if a nearby 48 VDC sensor line shares the same duct. The 50-pole count on the enclosure-side connector matches the standard 50-pin ribbon-cable interface used on many S7-300/1500 connection modules; the 16-pole front connector side breaks it into four groups for the module's front connector rows.","metaTitle":"Siemens 6ES7923-5BC00-0EB0 Pre-assembled Round Cable, 2 m, f","metaDescription":"Active production Siemens 6ES7923-5BC00-0EB0 pre-assembled round cable, 2 m, 50-pin IDC, for SIMATIC S7-300/1500 digital I/O modules.
