- optical sensor
Length of wave emitted : 890 nm.
Power of light emitted : Depends on the distance sighted.
at 1 cm: 0.5 mw/cm²
at 50 cm: 2 mw/cm²
Minimum power of light received : 10 µW/cm²
Ratio of reflective surface/target surface : > 5 %
Detection distance : from 1 to 50 cm
Sighting angle in relation to the perpendicular of the target : 0° ± 15°
- mechanical adaptor
Accessory which makes it possible to transform the optical sensor into a sensor in
mechanical contact with the moving part.
- pointed tip accessory
This tip allows measurement by contact at the end of the axle of a rotating system.
It is a rubber cone which is fitted to the output axis of the adaptor.
Minimum diameter of the measurement axle : 5 mm
- cylindrical tip accessory
This tip allows measurement by contact at the end of the axle of a rotating system.
It is a rubber cylinder which is fitted to the output axle of the adaptor. It allows the
measurement of the rotational speed of shafts with a diameter less than 5 mm or
with a flat end.
- wheel tip accessory
This tip allows the measurement of linear speed by direct contact with the moving
part.
It is a rubber non-deformable wheel which fits onto the output axis of the adaptor.
Diameter of the wheel : 30.183 mm
Development of the wheel : 10 cm ± 0.1 mm
