MUCH MORE THAN CONTACTLESS LENGTH MEASUREMENT
With the VO330570, ipf electronic presents an inline
incremental encoder that detects all moving objects without
contact, regardless of material and color. As the device works
with infrared light of laser class 1, no special safety precautions
are required during installation. Due to the very high sensing
rate of 0.9ms, the VO330570 is particularly suitable for
detecting materials in very high-speed processes.
The VO330570 is also capable of performing a trigger function,
i.e. emitting a start pulse, e.g. for marking devices, as soon as
a previously defined increment value is reached. The sensor is
parameterized via a free PC software (interface: Micro-USB),
whereby the units pulse/mm, m/min and mm are available.
The particular advantage of this optical system is the
contactless measurement, as no mechanical components are
used, meaning that the solution works without slippage and
is gentle on the material. In contrast to measuring wheels and
other mechanical methods, the VO330570 thus achieves a
higher measuring accuracy (± 0.3%), whereby the distance to
the surface to be sensed can be variably selected within the
device sensing range of 15 to 60mm.
For measurement, the sensor is mounted in a position in which
it can sense the surface of the products or materials vertically
from above, e.g. on a rotating shaft, on a conveyor belt or
over moving objects such as foils, cardboard boxes, plates,
packaging, etc.
The VO330570 is suitable for almost all materials and surfaces.
Even with reflective and smooth surfaces, the sensor is able
to provide optimum measurement results. The electrical
connection is made via a 6-pin M8 plug contact (voltage range 5
to 30V DC). Status messages are provided via 2 LEDs integrated
in the aluminum housing. (he)
