Siemens 6ES7922-3BC50-0AC0 Front Connector Cable Assembly

Siemens 6ES7922-3BC50-0AC0 Front Connector Cable Assembly is a pre-assembled front connector for SIMATIC S7-300 digital I/O modules. It features a 40-pole front connector connected to 40 single-core wires (0.5 mm², H05V-K), all terminated in a screw-terminal configuration and supplied in a 2.5 m length. The assembly is designed to connect directly to a digital I/O module in the S7-300 family, reducing wiring effort and cabling errors by about 50% compared with conventional field-wiring approaches. The part number denotes a 2.5 m front-connect cable for a 40-contact interface, suitable for automation setups using S7-300 DI/DO modules in industrial control panels and machine automation environments.
