M70LL Laser Distance Sensor

Transcription

1 M7LL Laser Distance Sensor for automated manufacturing with Ethernet interface to connect with PLC The analog sensors of series M7LL use a PSD for their receiver optics. This assures a position measurement at high-speed movements. Replacable protection glasses and a robust casing allow the use even in dirty environments.» 1 khz Measuring frequency for high-speed measurements Applications: Roundness Measurement: The sensor is mounted in a defined distance to the rotating object. Even smallest deviations from roundness are recognised due to a displacement measurement. IC check: To avoid error during placement the ICs are detected by a M7LL laser sensor. Bent or absent pins are realised and can be signaled to the machine control. Thus waste will be recognised immediately and the appropriate corrective action can be initiated without delay. Ethernet interface Analog output Ranges.5 mm up to 2 mm Measuring frequency 1 khz Low noise Reliable results also with white/black transition Replacable protection glasses Thickness Measurement: Two sensors are measuring onto the top and the bottom side of the target. The thickness of the object results from the measured distance values. Vibration Measurement: The M7LL measures die deflection of a membrane at vibrations up to 1 khz.
