Mapping Sensors
BWM Series
The BWM series mapping sensors are optimized for glass substrate detection with double scan method and excellent optical detection performance. The sensors can detect thin glass substrates with low levels of light reflection and support CC-Link and EtherCAT communication protocols. Users can easily check the teaching area using the installation instruction mode. The mapping sensors can be used to detect display panels on transport cassettes.

    Double Scan Method for Stable Glass Substrate Detection

    The master and slave units contain both emitter and receivers which allow detection of light amount from both sides, offering high optical detection performance. This double scan method allows detection of thin glass substrates with low levels of light reflection.


    Installation Instruction Mode and Auto Teaching Function

    The installation instruction mode allows users to check if the detection target object is in proper position using the output indicators. The auto teaching function allows all sensing channels to be set in uniform light amount for optimal sensitivity setting.


    Sensing Level Setting to Minimize Influence from Bent Glass or Scattered Reflections

    The sensing level setting allows optimal sensing with minimal influence from bent glass or scattered reflections. The sensing level can be set in 9 different sensitivity levels for stable detection in various environment settings. If the mapping sensor or cassettes are bent, sensitivity adjustments can be made without removing the glass substrates.


    CC-Link, EtherCAT Communication Protocol Support

    The units offer support for CC-Link or EtherCAT communication support and also offer options for connector type connection or terminal type connection.


    Mutual Interference Prevention Function

    When 2 or more units need to be installed near each other, users can set different frequency for each unit to prevent malfunction from mutual interference.


    Check Operation Status with Bright Indicators

    The bright indicators allow users to easily check operation and communication status even from long distances.
