The Siemens 6ES7922-5BJ00-0HC0 is a 40-pole front connector with pre-wired single cores, designed specifically for SIMATIC S7-1500 digital I/O modules. It comes with a screw-type terminal on the enclosure side and an 8-meter cable of 0.5 mm² H05Z-K halogen-free wire, color-coded blue (RAL 5010) with cores numbered consecutively 1 to 40. The connector mates with the 6ES7592-1AM00-0XB0 header on the module.
Rated at 24 V and max 30 V — this is the voltage rating of the connector assembly, not a module rating. The 40 poles match the full I/O count of a standard S7-1500 digital module, so one connector handles all field wiring for that slot. The 8 m cable length gives you a generous reach from the module to the first junction or terminal block inside the cabinet; for shorter runs the extra cable can be bundled, but it adds bulk at the module face. Screw-type terminals (not spring-cage) mean the field wiring is secured with a screwdriver — standard practice in panels where vibration is moderate and technicians prefer a positive clamp. The 0.5 mm² conductor cross-section is sized for signal-level digital I/O (sensors, actuators, 24 V DC loads); it is not intended for power distribution.
This connector is the field-side interface for SIMATIC S7-1500 digital input and output modules in control cabinets. It is suited for applications where a pre-assembled, halogen-free cable is required — common in food-and-beverage, pharmaceutical, and other environments with strict material compliance requirements. The H05Z-K cable sheath is polyolefin-based and halogen-free, reducing toxic smoke in a fire scenario.
