"Everything is relative
and only that is absolute"
according to the famous French philosopher Augusto Comte,
To examine his theory further, he believed that nothing
is as it seems and that all things are subjective realities
to the observer. Or put more simply, he considered that
everything is relative to each person, from their viewpoint
only.
In
this month´s e-Matters we would like to explore this whole
topic in a little more detail, so we would ask you, dear
Reader, to consider this question. Is one millimetre too
much or too little and does it matter or not?
For most of us, the answer to this question would be completely
dependent on the context. For example, one millimetre
would be crucial in many surgical procedures but when
calculating the actual distance between Paris and London
a measurement this small would be less significant.
However, in the automation industry a single millimetre
can often be the difference between a machine working
or not!
So
millimetres aside, we hope that you will find our
June edition of e-Matters of interest.

D-M9W
- our direct mounted type, solid state auto-switch for
accurate stroke end detection
|
Spot
at a glance the correct stroke position and avoid annoying
machine stoppages |
Typically
when an actuator is exposed to constant vibration,
any attached auto switches can move slightly and
this movement could cause real problems as the
switch could stop sensing the cylinders stroke.
However, if you use our new auto switch -Series
D-M9W - any switch movement can be detected in
its early stages thanks to its dual colour indicator
light.
|
|
 |
|
Even
the smallest movement will be clearly visible, as
the auto switch´s indicator light will turn from
green - within the optimal sensing range - to red
when the auto switch is outside its optimal exposure
range.
These high quality auto switches really do provide
extremely accurate, reliable and highly visible
stroke detection at a glance making potential machine
downtime due to auto switch slippage a thing of
the past. |
| The
performance of our Series D-M9W is clearly
explained in the chart below. |
|
 |
|
| |
|
As
you can see, even a single millimetre can make the
difference between perfect auto switch positioning
including optimum machine performance or time consuming
and expensive malfunction.
Our Series D-M9W auto switches can be selected when
ordering an actuator and are compatible with the
vast majority of our extensive actuator ranges.

Are
you aware of the existence of static electricity in your
factory?
All matter, whether solid, liquid or a gas is composed
of particles so small that they cannot be seen - even
with the most powerful microscopes. These particles are
called atoms and they are the building blocks of all chemical
elements. The word "atom" is Greek and it means "cannot
be split". But we now know that atoms can be separated
and that they split into protons, neutrons and electrons.
The protons and the neutrons form the atom´s nucleus.
Protons have a positive charge, whereas neutrons are neutral.
Electrons have a negative charge and they orbit the nucleus
like the planets orbit the sun.
Some
materials hold the electrons very tightly - so they cannot
move very easily - and these materials types are called
insulators e.g. plastic, cloth, glass or dry
air.
On the other hand, materials that allow the electrons
to move easily are called conductors and most metals fall
into this category.
Static
electricity is in fact generated whenever two materials
touch and then separate. One material charges positively,
and the other negatively. The charge which is generated
may not be noticed as often there is an electrically conducted
path which can dissipate the static electricity harmlessly
away. The build up of static electricty depends on whether
the rate of charge dissipation is greater than the rate
of charge generation. If the charge generation is greater
than the dissipation rate static electric charges build
up leading to electrostatic discharge (ESD).
|
|
Whilst
this explanation maybe a little basic...,
In your factory this phenomena could be
happening in processes such as:
Four
main ways to help prevent the build up of
Static Electricity
- Grounding or Earthing
- Humidity control
- Conductive Products
- The use of products
such as Ionizers - electrical devices that
help balance the charge by ejecting Ions.

way to fight against this invisible threat!
