Novotechnik’s
long-range absolute linear position sensors now available with
CANopen interface
Recently announced
by the German sensor specialist Novotechnilk, and available from
Variohm EuroSensor - its exclusive UK distributor, the long-range
TP1 and TH1 absolute linear sensors now have a CANopen interfacing
option.
Both of these models feature Novotechnik’s magnetostrictive
technology which provides touchless and wear-free linear position
measurement with up to 1 micron resolution over the entire travel
range up to 4250 mm. As a more robust alternative for long range
optical encoders, the TP1 has an enclosed housing and touchless
position detector that can be either fixed or floating, whilst
the TH1 comprises separate rod and ring-shaped position marker
components that allow integration into fluid power cylinders
or mobile machinery.
The CANopen fieldbus
option complies with CiA DS-301 V4.2.0 and device profile DS-406
V3.2, and includes position and speed signals for one or two
sensors. The industry standard profile provides a dependable,
robust and standardised option for data transfer with high immunity
to interference and straightforward set-up and installation.
The combination of CANopen and the extremely high durability
of the touchless technology, which is insensitive to shock and
vibration, brings new levels of reliability to demanding industrial
machinery and automation applications.
Both models offer
IP67/68 protection as standard and an integrated teach-in function
provides a calibration tool that, without external equipment,
can be built into the customer’s machine set-up. Throughout
the TP1 and TH1 series, a wide choice of electrical and mechanical
interfacing options are available, and custom options are available
on request.
