M12 B-coded 5-pin connectors are used for PROFIBUS DP fieldbus connections on sensors, drives, and I/O modules. The B-code key prevents mating with A-coded connectors used for other protocols.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VP | Positive supply voltage +5V | PWR |
| 2 | RxD/TxD-P | Receive/transmit data positive | BUS |
| 3 | DGND | Data ground | GND |
| 4 | RxD/TxD-N | Receive/transmit data negative | BUS |
| 5 | Shield | Cable shield | GND |
