Product details

The Siemens 6ES7922-3BC50-0AF0 is a 20-pole front connector with pre-terminated single cores for SIMATIC S7-300 digital I/O modules. It carries 20 individually numbered cores (H05V-K, 0.5 mm²) in a blue PVC sheath, terminated with crimp connections at the module end and stripped at the field end. Rated at 24 V with a maximum of 30 V, the 2.5 m cable length suits panel layouts where the I/O module sits within arm's reach of the terminal block row.

The connector mates with the S7-300 front-panel receptacle (matching connector 6ES7392-1AJ00-0AA0) and is designed specifically for digital signal transmission — not for analog modules. The 20 poles are numbered consecutively 1 through 20 on white adapter contacts, matching the core numbering.

Frequently asked questions

Where can I buy 6ES7922-3BC50-0AF0 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the maximum voltage rating for 6ES7922-3BC50-0AF0?

The maximum voltage is 30 V, with a rated value of 24 V for the digital I/O signal path.

What is the wire length and conductor size?

The cable length is 2.5 m, with each of the 20 single cores having a conductor cross-section of 0.5 mm² (H05V-K).

Will 6ES7922-3BC50-0AF0 work with analog S7-300 modules?

No — this front connector is specified for digital signal transmission only and is not suitable for analog signal modules.
