High-precision tension, pressure and flow control applications
The new analogue I/O units from Omron
offer a conversion resolution of 1 part
in 12 000, making them an ideal choice
for high-precision tension, pressure and
flow control applications, and for use with
measurement sensors in quality inspection
systems.The units available are input-only
versions with four analogue inputs, output-
only versions with four analogue outputs
and mixed I/O versions with four analogue
inputs and either two or four analogue
outputs. All versions support the full range
of standard current and voltage signals.
Omron’s new temperature sensors are
offered in two versions.The first has twelve
inputs for use with thermocouples, and is
well suited for use with extrusion mould-
ing machines and large ovens.The second
version has four thermocouple inputs,
two of which can optionally be configured
for use as standard analogue inputs (1 to
5 V, 0 to 10 V, or 4 to 20 mA). This version
allows temperature sensing and analogue
sensing to be combined cost effectively in
a single unit.
Both units deliver high accuracy and
performance, and they are complemented
by Omron’s PID function block and CX pro-
grammer, which make it easy to implement
temperature control systems.

Photoelectric sensors with PMD technology – and Laser Class 1
The tried-and-tested photoelectric O5D sensors from
ifm electronic are distinguished by switch point set-
ting to the nearest centimetre, colour-independent
detection and reliable background suppression.
The PMDLine series even detect shiny surfaces
without any difficulty. ifm has now extended this
sensor family with laser class 1 allowing it to meet
the requirements of applications in the automotive
industry.
In its compact housing, the O5D variant combines
long range, reliable background suppression, visible
red light and high excess gain – plus laser class 1.
Another advantage is its ease of use and switch point
setting to the nearest centimetre via +/- buttons and
display.The O5D family is an intelligent alternative
to standard sensors, since their price and size are
in the same range.
