By eliminating the traditional ferrite core, Uprox+ Sensors
offer many advantages over the old design. One of the primary
advantages is Factor 1 sensing i.e. the ability
to sense all metals equally:
materials
such as iron, stainless steel, copper, aluminium and brass. Ferrite core sensors are rated by their
ability to sense a mild steel target but suffer huge loss of
sensitivity
(Reduction Factor) when detecting other metals.
(See Reduction Factors).
This concept
also offers extraordinarily high
switching distances, some
250% higher than that of conventional inductive sensors.
Another
advantage with Uprox+ is an increased switching speed, making
them an ideal choice for applications such as rotational speed
monitoring.
As Uprox+
sensors do not have a ferrite core, they are not susceptible to
strong magnetic fields that occur in electric welding processes.
This inherent protection makes them ideal for automated welding
production lines.
Uprox+
affords a high level of EMC protection as not only do they fulfil the present standard EN50082-2
but also exceed the strict requirements of EN61000-4-6 that will
become the proximity switch standard from 2007
onwards.
All Uprox+
sensors have an environmental rating of IP 68 and
provide an extended temperature range.
Conventional
non-flush sensors are very sensitive to metal surfaces around the
sensor body which can render the sensor unusable. The Uprox+
non-flush
sensors provide unique flexibility due to the integrated pre-damping
protection function. Non-flush Uprox+ sensors may be embedded in metal up to
the upper edge of the thread with no more than a 20% reduction
in switching distance. Try this with a standard sensor and it just
stays ON.
Uprox+, reduces the need for costly ‘specials’ meaning less
inventory cost for spares.
