Siemens 6ES7922-3BF00-0AB0 SIMATIC TOP Connect Front Connector 20-Pole 5m PLC Connection Module

The Siemens 6ES7922-3BF00-0AB0 is a pre-assembled 20-pole front connector for SIMATIC S7-300 digital I/O modules, terminating 20 individual 0.5 mm² H05V-K cores in a screw-type version with a 5 m cable length. It plugs into the module in place of the standard front connector and brings each of the 20 numbered cores out to field terminals for direct wiring of sensors and actuators.

Technical Specifications

Selection Notes

This is the 20-pole variant, sized for S7-300 digital I/O modules with up to 20 channels; a 40-pole version exists for modules with more channels. Pick the single-core screw version over a modular TOP connect junction system when each channel needs to land on its own numbered terminal or relay rather than a shared connector block, and confirm the 5 m length covers the run from module to terminal strip before specifying it.

Applications

Hard-wiring SIMATIC S7-300 digital input or output modules to a cabinet terminal strip without a modular TOP connect junction system, for point-to-point connection of sensors, actuators, and other discrete I/O at up to 30 V DC / 1.5 A per core.
