The cable runs 2.5 m from the connector body to the bare ends, so it reaches a standard DIN-rail terminal block inside the same enclosure without a splice. Rated at 24 V with a maximum of 30 V, it is sized for the 24 VDC control voltage typical of S7-300 digital input and output modules. The connector body mates with the 40-pin receptacle on the module face (6ES7921-3AH20-0AA0), and the crimp termination at the module end means you push the cores into the cage clamp — no screwdriver needed on the connector itself. The 24 V rated value and 30 V maximum are the voltage limits for the signal wiring inside the cable sheath — not a power rating. The 0.5 mm² conductor cross-section handles the typical 10–20 mA per channel of S7-300 digital I/O without voltage drop over the 2.5 m run. The blue PVC sheath (RAL 5010) and numbered cores make panel wiring traceable back to the module channel. The 40 poles match the full channel count of a 32-channel digital I/O module plus the预留 pins for the module's internal bus and power supply. The crimp connection at the module end is the standard for S7-300 — no soldering, no screw terminals on the connector body itself.","metaTitle":"Siemens 6ES7922-3BC50-0AG0 front connector, 40-pole, 2.5m ca","metaDescription":"Siemens SIMATIC S7-300 front connector with 40 single cores, 0.5 mm², 2.5 m cable length, rated 24 V, max 30 V.
