1. Safety precautions
·
Use supply voltage and interfaces indicated in the sensor specifications.
·
In connection/disconnection of cables, the micrometer power must be switched
off.
·
Do not use micrometers in locations close to powerful light sources.
·
Sensor windows should be kept clean. Do not clean the glass with abrasive and
aggressive cleaning agents.
·
If the windows are accidentally touched with fingers, they should be wiped
immediately.
2. CE сompliance
The sensors have been developed for use in industry and meet the requirements of
the following Directives:
·
EU directive 2014/30/EU. Electromagnetic compatibility (EMC).
·
EU directive 2011/65/EU, “RoHS“ category 9.
3. Laser safety
Continuous LED light source is installed in the sensor. Sensors belong to Class 1.
4. General information
The sensors are intended for non-contact measuring and monitoring the position of
the edge (edges) of various objects, such as tapes, plates, substrates, etc.
5. Structure and operating principle
The sensor operation is based on the so-called ‘shadow’ principle, Fig.1. The
sensor consists of controller and measuring head which consists of two modules –
transmitter and receiver.
Transmitter module consists of LED (1) and lens (2). Receiver module includes a
photo-detector array (3).
Radiation of the LED (1) is collimated by the lens (2) and directed to the photo-
detector array (3). With an object placed in the collimated beam region, shadow image
formed is scanned with the photo-detector array (3). Controller calculates the position of the
edge of the object.
