About the Siemens 6ES7392-1BM01-0AA0

The Siemens 6ES7392-1BM01-0AA0 is the spring-loaded version of the 40-pole S7-300 front connector; its screw-terminal twin is the 6ES7392-1AM00-0AA0. It fits 40-pin signal modules such as the 32-channel SM 321 and SM 322. Siemens's data sheet gives conductor cross-sections of 0.14 to 0.75 mm² (AWG 24 to 19) and a 6 mm stripped length, and Siemens names it as the spring-loaded connector for the SM 322 relay module 6ES7322-1HF10-0AA0. Siemens's data sheet marks it as a spare part.

What is the 6ES7392-1BM01-0AA0 used for?

It carries the field wiring onto a 40-pin S7-300 signal module: the cables land on the connector, which plugs onto the module's front.

Lifecycle and successor

Discontinued.
