Description
Overview
The TL50 contrast sensor line offers
the best solution for all the applications
where cost reduction is requested,
without compromising the excellent
detection performances. The optimised
optics of these sensors, the RGB
LED emission with automatic colour
selection and the very fine resolution,
allow the detection of the weakest
contrast of colours or grayscale
between mark and background, or
between different objects or surfaces.
The high resolution is not a limit for
the detection speed, reaching 33 ms
response time and 15 kHz switching
frequency. Thanks to the compact
dimensions and multiple fixing
holes with metallic inserts present in
standard positions, the sturdy ABS
plastic housing is fully compatible
and can replace the most traditional
contrast sensors, as well as offering an
interesting cost reduction.
The special PMMA plastic lens, that
can be fixed either in an axial or lateral
position, is suitable for sensor use in
the food industry, where the presence
of glass parts must be avoided.
