It terminates field wiring to the module via a screw-type terminal block on the enclosure side, with 20 individually numbered cores (H05V-K, 0.5 mm²) bundled in a blue PVC sheath. The cable runs 2.5 m from the connector body to the bare ends — enough to reach a standard DIN-rail marshalling point or terminal strip inside the panel. Rated at 24 V with a maximum of 30 V, this connector handles the standard S7-300 backplane voltage for digital signals — 24 VDC nominal, 30 V absolute ceiling. The 0.5 mm² conductor cross-section is sized for the signal-level currents typical of digital inputs and outputs; it is not rated for analog signal transmission. ## Integration Notes The connector mates with the 20-pin receptacle on S7-300 digital I/O modules (part number 6ES7392-1AJ00-0AA0). The screw-type terminal on the enclosure side accepts the pre-wired single cores; core numbers 1 through 20 are printed on white adapter contacts, matching the module's terminal assignment. The blue sheath (RAL 5010) and PVC insulation are standard for the S7-300 signal cable family.","metaTitle":"Siemens 6ES7922-3BC50-5AB0 Front Connector, 20-pin Screw, 2.","metaDescription":"Siemens 6ES7922-3BC50-5AB0 front connector for SIMATIC S7-300, 20-pole screw-type, 2.5m single cores 0.5mm².
