1. Safety instructions
1.1 Symbols
The symbols in these instructions point out risks and have the following meaning:
Warning in case of risks.
Non-observance can result in malfunctioning.
Non-observance can result in malfunctioning and
personal injury.
Information on proper product handling.
1.2 Intended use
• The KINAX 2W2 is a precision instrument. It is used to determine angular po-
sitions, processing and providing measured values of electrical output signals
for the downstream device. Encoders use for this purpose only.
• The angular position transmitter is not intended to measure rotation speed.
• The device is intended for installation in industrial plants and meets the requi-
rements of EN 61010-1.
• Device versions with explosion protection may only be used in the planned
purposes and have to be installed in a housing with an ingress protection of at
least IP20 according to EN 60529. The operation in other explosive atmospheres
is not permissible.
• Manufacturer is not liable for any damage caused by inappropriate handling,
modifi cation or any application not according to the intended purpose.
1.3 Commissioning
• Installation, assembly, setup and commissioning of the
device has to be carried out exclusively by skilled workers.
• Observe manufacturer’s operating instructions.
• Check all electric connections prior to commissioning the
plant.
• If assembly, electric connection or other work on the device
and the plant are not carried out properly, this may result
in malfunctioning or breakdown of the device.
• Safety measures should be taken to avoid any danger to
persons, any damage of the plant and any damage of the
equipment due to breakdown or malfunctioning of the
device.
• Do not operate the device outside of the limit values stated
in the operating instructions.
• Operation of device versions with explosion protection is
only permissible when...
- the details on the type label of the device match the on-
site conditions for the permissible Ex area in use (group
of equipment, equipment category, zone, temperature
class or maximum surface temperature)
- the details on the type label of the device match the
electrical supply network
- the device is undamaged and
- it has been checked that there is no explosive atmos-
phere, oils, acids, gases, vapors, radiation etc. present
during installation.
1.4 Repair work and modifi cations
Repair work and modifi cations shall exclusively be carried
out by the manufacturer. In case of any tampering with the
device, the guaranty claim shall lapse. We reserve the right
of changing the product to improve it.
1.5 Disposal
The disposal of devices and components may only be realised
in accordance with good professional practice observing the
country-specifi c regulations.
1.6 Transport and storage
Transport and store the devices exclusively in their original
packaging. Do not drop devices or expose them to sub-
stantial shocks.

- Transmitter for angular position KINAX 2W2, acc. made to order
- 3 clamps
- 1 Operating instructions in German, French and English
- 1 Type examination certifi cate, only with ATEX-approval
3. Application
The KINAX 2W2 transmitter converts the angular position of a shaft into a
load
independent
direct current signal, proportional to the angular position.
Due to the compact design, the angular position transmitters are particularly suitable
for installation in or mounting / on devices and apparatuses.
Explosion-proof “
Intrinsically safe Ex ia IIC T6
” versions with I.S. meas uring output
rounds off this series of transmitters.
4. Main features
• Compact angular position transmitters for installation or mounting
• Capacitive scanning system
• 4...20mA analog output signal with 2-wire connection
• Drive shaft without stops, rotating
• Low starting troque < 0.001 Nm
• Non-wearing and low-maintenance
• Adjustment / Independent fi ne adjustment of the analog output, zero position
and measuring range
• Characteristic of the output value / Programmable as a linear, V-characteristic,
or any characteristic curve
• Wirh explosion prevention „Ex ia IIC T6 Gb“ according to ATEX available
