General information
The light curtains of the CML 700i series are designed as measuring and object-detecting, configurable,
multi-sensor units. Depending on the configuration and model, the devices are suitable for a variety of
tasks with various resolutions and can be integrated in different control environments.
The total system of the light curtain consists of a transmitter and a receiver, including the connection and
interconnection cables.
• Transmitter and receiver are connected to one another via a synchronization cable.
• The integrated control panel with indicators and operational controls for configuring the total system
is located on the receiver.
• The shared power supply is provided via connection X1 on the receiver.
