M.1016.2568

M.1016.2568 is a Danaher component in the Block IO Analog Modules series. Its cable uses twisted-pair construction to help reduce interference between signal lines. It contains four 24 AWG conductors, providing separate paths for transmit and receive signals. Each pair is individually shielded to limit exposure to external electrical noise.

The connection uses a 9-pin male D-sub connector. The transmit pair connects to pins 3 and 4 and carries outgoing signals through white and black wires. The receive pair connects to pins 5 and 6 and carries incoming signals through red and black wires. This color coding helps distinguish the transmit wiring from the receive wiring during installation and maintenance.

The cable shield connects through pin 7 or the connector shell, providing a path for shielding continuity and noise control. Pin 7 serves as the dedicated shield pin. Pins 1, 2, 8, and 9 are not connected, separating unused connector positions from the active transmit, receive, and shield connections.
