GENERAL PRODUCT INFORMATION
Due to their design of 0.7 mm to 2.2 mm and their
simple adaptation to customer requirements, mem-
brane potentiometers from ETI Systems are the
perfect solution for restricted installJtion conditions.
The technical specifications ofthe membrane
potentiometers correspond to those of conventional
precision potentiometers or even surpass these.
They offer an attractive cost advantage and are easy
to use.
Standard elements of 50 mm to 500 mm are avail-
able, as well as very favorably priced customer-
specific variations. In particular, the good repeat
accuracy, the easy to achieve redundancy and the
problem-free integration represent decisive
advantages. The potentiometer
follows
the shape and
function of the specific application: linear, circular
or customer-specific shapes are available, on
request also with non-contact connection.
Depending on various parameters, the service life
comprises
1
million cycles to 20 million cycles and
the
repeat accuracy 1 mm to O.5mm. The standard
products are sealed to
IP
42 with an
loptional
sealing
to IP67
lNEMA4X.
HOW DOES
IT
WORK?
Membrane potentiometers are used as voltage dividers and
consist of several layers, which are seperated by a spacer.
These layers are connected to each other through mechanical
or magnetical pressure and create a contact. The contact can
be made either by hand or by using a mechanical wiper
(see
picture). It is also possible to have a non-contact operation by
using a magnet instead of a wiper.
CUSTOMIZED DESIGN
There are virtually no limitiations when it comes to the
customization of membrane potentiometers. No matter if
linear, rotary or custom shaped with membrane technology
almost any customer requirement can be fullftlled.
