Arcs and curved axes: all they take is the right encoder
Don’t settle for any transducer: incremental SMR5H and absolute SMLA encoders
are specifically designed for accurate installation and measurement
on arcs and curved surfaces up to 360°.
Following several custom requests, Lika Electronic has developed
a specific range of contactless encoders ideally
suited for installation on round axes up to 360° & arcs
with virtually any diameter.
SMR5H is a quadrature incremental encoder specifically
engineered for installation on the inner side of arcs from
176 mm / 7” min. diameter up. It will be available also for
full circumference soon. SMR5H is compact, has a shallow
profile (15 mm / 0.59” depth) and even better is curved-shaped;
this allows it to fit into arcs with constrained and tight
mounting space (such as inside a torque motor enclosure)
and guarantees quickness and ease of installation. It is contactless
and encompasses a proven magnetic technology
fully integrated into a rugged and hermetically encapsulated
housing with IP67 protection rate. Thus it is ideally
suited to operate in aggressive industrial environments and
provides virtually wear & maintenance-free operation under
tough conditions such as when dirt, moisture, oil, vibrations
and shocks are present. The sensor generates square wave signals
with complementary signals through either Push-Pull
(HTL) +10-30Vdc or Line Driver (TTL) +5Vdc output circuits.
Resolutions are on request. As an additional advantage,
SMR5H is equipped with built-in sensor to provide the Reference
signal. Furthermore it is fitted with integral LEDs to signal
power on status and reference sensing. Please note the
lateral cable outlet to save space and increase convenience.
When it comes to highest precision needs on curved surfaces
up to 360° SMLA absolute encoder is the perfect
match. It offers resolutions up to 14 bits over 400 mm / 15.7”
measuring length (longer travels available soon). Output circuits
can be SSI or BiSS-C and they both provide alarm bits.
The magnetic sensing technology allows for non-contact
and frictionless measuring principle with no components
subject to wear or fatigue. Furthermore SMLA affords excellent
durability under adverse conditions and temperatures
(-25°C +85°C, -13°F +185°F) thanks to the encapsulated
electronics and its IP68 protection aluminium enclosure.
This guarantees reliability over time and longer operating
life. Remarkable speeds up to 15,000 rpm and 16 m/s can
be achieved.
High performance and resolution enable a typical use
in industrial applications that need the greatest precision
and accuracy such as in fast pick & place robots and delta
robots as well as in 3D printers, but it is suitable also for
electronic assembly systems and precision material handling
equipment to move highly fragile products. It is effectively
used also to measure the rotation of the rollers on folding
machines.
Lika Electronic is able to supply all-in-one measuring systems
with incremental or absolute encoder and custom
curved structures on request.
