Dual sensor IND type
IND units combine
two distinct inductive proximity sensors in a single,
double insulated,
IP 67 housing. One
sensor provides a
signal when the
valve is open, the
other when it is
closed. The units
are invaluable for
confirming that
power-operated
Clearly visible position
indicators:
LEDs indicate current position
and switching status as well as
markings located on the target
puck.
Robust housing:
IND type sensors incorporate two
distinct inductive elements in a
housing sealed to IP 67. The
tough housing will also withstand impacts allowing their use
in any application.
Compatible with
VDI / VDE 3845:
All IND sensors are compatible
with VDI / VDE 3845 guidelines
meaning they are simple to fit
to nearly any actuator.
Connection opportunities:
Versions with integrated AS-i
chips allow simple addition to
AS-i networks, M12 cabled
versions and units with a
terminal chamber mean that
ifm’s INDs are the simplest
choice for valve control.
4
Unit with terminal chamber:
Two captive screws above the cable
gland enable easy opening and closing
of the terminal chamber.
The wiring can be maintained if the
sensor is replaced, thanks to the
removable terminal block.
As an option, a solenoid valve can be
triggered.
Position feedback on
quarter-turn actuators.
By using state-of-the-art production
technologies it has become possible to
incorporate the latest AS-i technology
with sensors and switching outputs in
a space-saving housing.
All these features facilitate mounting,
set-up and maintenance for the user
and increase uptime of the whole
AS-Interface system.

VDI / VDE 3845 is a
guideline which
defines, amongst
other things, the
mechanical mount-
ing arrangements
for fitting switch
boxes to actuators.
The IND units have
been specifically
designed to conform to and take
advantage of this
guideline, allowing them to be
fitted to the majority of actuators
with the minimum
of effort.
Positionfeedback on
quarter-turn actuators
and manual valves
are in the appropriate position for
correct and safe
operation in all
types of process
plant.
Many accessories are available including target
pucks for most valve actuators. The selector
facilitates the selection of pucks for different
quarter-turn actuators.

Namur IND units used with quarterturn valves installed on an oil tanker.
Sensors with ATEX Cat. 1D/1G/2G were
chosen because of the installation
inside an explosive area.

Feedback system
efector valvis IX type
Requirement:
Everywhere in the
food industry
valves are used for
shutting off, monitoring and controlling. They are decisive components
for the safety, accuracy and reliability of plants.
Implementation:
Conventionally,
magnetic or inductive proximity
switches assume
this task. They
signal end stops
such as ”open” or
”closed” to the
controller by
means of a switched signal.
AS-i integrated:
AS-Interface from ifm is the ideal
way to communicate feedback
from multiple valves and is incorporated, as standard, in the
efector valvis.
Freely programmable:
With 3 switching outputs, the
efector valvis gives reliable
indication of the valve piston’s
position: open, closed or seat lift.
For a comprehensive selection
of accessories and adapters for
efector valvis see www.ifm.com.
Simple set up:
Uncomplicated programming by
pushing a button replaces
mechanical adjustment to the
respective valve positions.
Adapters:
Rising stem valves differ of
course, so a range of adapters for
many valve types, for example
Alfa Laval, Südmo, GEMÜ and
Georg Fischer, are available.

Easy position setup due to freely
programmable switching outputs.
They transmit the actual limits of
travel to the controller.
Continuous position feedback on single,
double seat and diaphragm valves.

Positionfeedback on
quarter-turn actuators
However, the detection of intermediate positions is
of increasing interest. It allows the
detection of
cleaning cycles for
rising stem valves
as well as the
visualisation of unintended operating states by
means of continuous valve detection. This is the
only way to meet
the growing
requirements of
modern process
visualisation.
Positionfeedback on
rising stem valves
or inside switchboxes
With thanks to different adapters,
efector valvis can be mounted on
various valve types. In this case it is
installed on an ON-OFF diaphragm
valve. I.e. two switching points have
to be set up. By missing the “Seat”
position out, the sensor realises that
only two switching points are needed.
efector valvis was designed for
feedback of the valve positions on
rising stem valves with a stroke of up
to 80 mm. The sensor is fitted over
the valve spindle and continuously
measures the stroke. This shows an
installation on double seat valves, all
three switching points are used.

Inductive sensors
IF, IG, II and IS type

quarter-turn actuators
Position feedback on
rising stem valves or

Robust:
Food-grade:
Housing materials such as
stainless steel in combination
with PEEK or pure stainless
steel sensors.
The sensors undergo a hard test program of temperature cycle, steam
boiler, vibration, shock and temperature
This procedure guarantees the highest
operational reliability for any
conditons in the food industry.
Flexible:
Common housing types and
lengths for installation in different applications. Increased
sensing ranges ensure flexible
installation for mechanical
tolerances.
Ingress-resistant:
The ingress resistance to
protection rating IP 69K prevents
moisture penetration.
Safe connection:
ecolink EVT – the ideal connector
for hygienic and wet areas:
PVC cables and housings plus
stainless steel coupling nuts
provide protection to IP 69K.
The common valve boxes can be used
with the square-shaped sensors of
type IS.
Customer-specific versions such
as platinum connectors facilitate
installation.
