It carries 40 poles on a round PVC cable, 8 m long, with 0.5 mm² conductors. The enclosure side terminates on screw-type terminals; the field end uses a connector strip. Rated for 24 V (max 30 V), it handles both analog and digital signal transmission. The 30 V maximum and 24 V rated value tell you this is a 24 VDC signal cable — it's not rated for power distribution. The 40 poles match the standard S7-300 front connector (6ES7392-1AM00-0AA0), so it drops directly into that slot. The 8 m length is generous for routing from the rack to a remote I/O cabinet or junction box. Screw terminals on the enclosure side are field-serviceable; the connector strip on the field side mates to the MTA backplane. The round PVC cable (outer diameter 7.6 mm bundled) is flexible enough for cable tray or conduit runs. This cable and connector assembly is purpose-built for the SIMATIC S7-300 PCS7 MTA system — a process-control variant of the S7-300 used in chemical, pharmaceutical, and water treatment plants. It connects the I/O modules on the S7-300 rack to the MTA termination board, where field wiring lands. The 40-pole density suits high-channel-count analog and digital I/O clusters.","metaTitle":"Siemens 6ES7922-3BJ00-0BB0 pre-assembled front connector MTA","metaDescription":"Pre-assembled front connector MTA (6ES7922-3BJ00-0BB0) for SIMATIC S7-300 PCS7, 40 poles, 8 m cable, 0.5 mm², screw terminals.
