Variohm EuroSensor signs distribution deal with Avtron for magnetic
technology rotary encoders
Variohm EuroSensor,
the electronic component distributor and manufacturer for specialist
sensors, has added a new range of magnetic technology rotary
encoders to its comprehensive position sensor range following
a new UK and Ireland distribution agreement with the USA based
technology leader, Avtron Industrial Automation Inc.
The agreement
brings Avtron's Wide-Gap™ magnetic sensing technology to
Variohm providing extremely durable, highly safe and exceptionally
reliable solutions for rotary position sensing in oil and gas,
wind turbines, cranes, mining and many other 'heavy' engineering
applications.
As an alternative
to optical encoders which can be fragile and damaged by contamination,
the wide-gap magnetic technology used in Avtron encoders can
'see through' dust , dirt water, oil and grease. The non-contacting
technology uses a rotor system with radial north and south pole
inserts and a stationary, magnetoresisitive sensor. Version are
available as separate rotor/stator units without bearings or
as fully housed and sealed assemblies for severe duty use complete
with support bearings. Diagnostics can be built into the assembly
allowing users to remotely identify problems before costly shutdown
is required.
Avtron's latest
hollow-shaft magnetic encoder, the XT45, is aimed at offshore
oil-rig position sensing applications. It has a 5000 ppr resolution
with full quadrature A,B and Z channel output - and boasts a
severe duty specification that includes a shock rating to 300
g, vibration to 20 g in any direction with an operational temperature
range from -40º C to +100º C. The labyrinth sealed
encoder is rated to IP67 and a polyurethane enamel paint finish
shrugs off dirt, oil, mild acid and salt water contamination.
It has universal 5...24 V operation, a self diagnostic alarm
output and is fully protected from wiring problems and surges.
Variohm EuroSensor
designs, develops and sources a comprehensive range of position,
load, force, vibration and other sensor technologies, and provides
complete pre-sale and post-sale application support for demanding
measurement applications throughout industry, agriculture, construction,
autosports, and research.
