    13/31 8 Electrical Connections LCI1220 and LCI1620 sensors are powered by using a PushPull type 4-pin cable with Harting Power connector. For input signals which can be used for synchronization purposes 10-pin PushPull type cables with Harting Signal Connectors is used. The sensor communicates with PC via Optical cable with SFP+ 10G transceiver modules.
