This is the part that bridges the module's backplane bus to the field wiring — the spring-cage termination means you push in a ferruled or solid conductor and it locks without retightening, which is the preferred termination in high-vibration panels and for faster installation on multi-channel I/O racks. ## What the 40-pin spring-contact termination means for the panel The 40-pin count matches the wide S7-300 signal modules (SM 331 analog input, SM 332 analog output, SM 321/322 digital I/O with 32 channels). Spring contacts eliminate the screw-torque check during commissioning — the cage clamps the conductor when you push it in, and the release requires a screwdriver to open the spring. For a dairy or beverage line where the panel sees daily washdown humidity, the spring contact avoids the corrosion creep that can loosen a screw terminal over time.","metaTitle":"Siemens 6ES7392-1BM00-0AA0 Front Connector","metaDescription":"Siemens 6ES7392-1BM00-0AA0 SIMATIC S7-300 front connector for signal modules with spring contacts, 40-pin.

It does not fit the narrower 20-pin modules (which use the 6ES7392-1AM00-0AA0 variant).
