It mates with the 40-pin front connector receptacle (6ES7392-1AM00-0AA0) and comes as a VPE of 5 units, each with a 2.5 m cable length. Rated at 24 V with a maximum of 30 V, this connector is designed for the signal-level voltages typical of S7-300 digital I/O — not for power distribution. The 40 poles match the full I/O capacity of a 40-channel module, so one connector handles an entire card's field wiring. Each core is 0.5 mm² H05V-K PVC-insulated, blue sheathed, with a 2.2 mm outer diameter per bundled core. That cross-section suits standard PLC signal loads (sensors, actuators, indicators) but is undersized for any load over about 1 A — stay within the module's output current per channel. ## Deployment context This connector lives inside the control cabinet, wired from the screw terminals on the module face to the terminal blocks or junction boxes in the panel. The 2.5 m length is generous for a standard 800 mm deep enclosure — it reaches from the rack to a nearby DIN-rail terminal strip without a splice. The cores are consecutively numbered 1 to 40 on white adapter contacts, matching the module's channel numbering, which saves time during commissioning and troubleshooting.","metaTitle":"Siemens 6ES7922-3BC50-5AC0 Front Connector, 40-Pole, 2.5m","metaDescription":"Siemens SIMATIC S7-300 front connector with 40 single cores, 2.5 m wire length, screw-type terminals, rated 24 V / max 30 V.
