TURCK
has introduced the high speed Q25 inductive linear
sensor to the automation market. The internal measuring
frequency is user selectable and can be as high as 5 kHz
resulting in accurate measuring speeds of five metres per
second. This high measuring frequency allows the Q25 to
provide real time monitoring and measuring, resulting in
more precise control than previously available in other
linear measurement systems.The Q25 inductive linear posi-
tion sensors do not require a magnetic position device and
are unaffected by metal debris commonly found in many
industrial applications.The sensors provide high resolution
and can be used to accurately measure lengths up to 1 m.
“We developed the high speed Q25 inductive linear sensor
in response to requests for a faster response time” saidMarty
Cwach, product manager at TURCK. “With faster response
time for a linear position sensor, our customers will be able
to improve machine speed and production efficiency.”
TURCK’s linear inductive sensor operation is based on
the RLC resistance inductance capacitance principle. Unlike
potentiometric or magnetostrictive technologies, the sensors
incorporate precisely manufactured printed emitter and re-
ceiver coil systems.The emitter coils are activated with a high
frequency ac field and produce an inductive RLC circuit with
the positioning element.The element is inductively coupled
with the receiver coils, which are arranged so different volt-
ages are induced in the coils, depending on the position of
the actuator.The voltages serve as a measure for the sensor
signal. Q-track sensors deliver maximum measuring spans,
with minimal blind zone and high resistance to EMI/ RFI
noise interference.
The high speed integrated processor converts the signals
into a 25 bit grey code SSI signal which can be connected to
by an 8 pin M12.The Q25 high speed inductive linear sensors
are a very compact design as compared to other designs
based on magnetostrictive technologies. TURCK offers the
Q25 in 10 standard measuring lengths starting at 100 mm
with 100 mm increments up to 1 000 mm. The Q25 has ex-
tremely short blind zones of only 29 mm on each side, is IP67
rated along with a wide temperature range of -25 to 70°C.

Machine builders can easily implement required safety functions while
improving productivity with the Allen-Bradley Guardmaster 440C-CR30
safety relay from
Rockwell Automation
.
Users can programme the safety relay through the free Connected
ComponentsWorkbench software fromRockwell Automation. Connected
ComponentsWorkbench software reduces programming time and helps
increase productivity by allowing users to create, control and monitor a
safety system in the same software environment as their standard con-
trol.The Guardmaster 440C-CR30 safety relay meets PLe, SIL 3 according
to EN ISO 13849-1 and IEC 62061. It is ideal for applications requiring
four to nine safety circuits and control of up to five zones.
“Machine builders across all industries are seeking safety solutions
that go beyond meeting compliance requirements to help significantly
increase both configuration and operation productivity,” said Christo
Buys, business manager control systems, Rockwell Automation sub-
Sahara Africa. “The flexible, compact Guardmaster 440C CR30 safety
relay configured via Connected ComponentsWorkbench software meets
their needs for improved safety, uptime and productivity.”
The distinct graphical user interface and drag-and-drop capabilities
of the software help guide users through a simple process of selecting
certified safety function blocks for the safety relay. Once programmed, an
embedded Modbus interface allows the safety relay to easily communi-
cate diagnostic data toAllen Bradley Micro800 controllers, Allen-Bradley
PanelView graphic terminals or Allen Bradley CompactLogix controllers.
Leveraging the embedded communication capabilities and the soft-
ware allows users to easily monitor, troubleshoot and quickly modify
their applications, including performing partial or conditioned shut-
downs, as needed. Five status and 16 user-configurable LEDs on the
safety relay’s faceplate provide local diagnostics to further aid in status
reporting and troubleshooting.
With 22 on-board safety I/O points, including six configurable I/O, the
Guardmaster 440C CR30 safety relay is the ideal solution for applica-
tions requiring multiple safety zones.Without growing the footprint, the
safety relay also can be expanded with two standard Micro800 plug-in
modules to support 16 additional standard I/O points, saving valuable
safety I/O points for user safety systems.
