SMG: the miniature modular encoder for toothed-wheels and racks
Lika Electronic continues its commitment to expanding the application specific product range
by introducing to the market the new SMG incremental modular encoder for toothed-wheels
and racks.
SMG is the incremental modular
encoder from Lika Electronic specifically designed to sense a variety of
toothed profiles with different pitches in both rotary and linear
installations such as toothed-wheels and racks. It features a very
compact and space-saving bearingless design with dependable
magnetic scanning. The magnetoresistive sensor head measures only
about 40 x 20 h mm (1.57” x 0.79”)
with a very shallow profile (17-mm
/ 0.67” thickness). The extremely
small dimensions enable the encoder to be easily mounted on spindles, drives and electric motors.
SMG is contactless and wear-free;
furthermore it is insensitive to dust,
water, oil, grease and interferences
thanks to the rugged metal enclosure and the full circuitry encapsulation (IP68 protection rate). Thus it
offers virtually maintenance-free
enduring service even in the most
demanding conditions and under
moisture, vibrations and mechanical stresses. SMG is designed to provide either AB digital signals with
complementary through Line Driver
output circuit or sine-cosine signals
through 1Vpp output circuit.
An additional Reference signal can
be provided on request. The pulse
frequency is up to 200 kHz.

New SMA: Lika's linear encoder at its best
SMA magnetic linear encoder delivers finer resolution at faster speed over longer measuring
length: it is perfect for motion feedback applications and linear motors that require
high-precision positioning and velocity control.
SMA is the linear absolute encoder capable of gaining the top of
Lika's range thanks to the many
new features and improvements.
It is ideally suited for applications
where small size and fine resolution
are mandatory such as linear
motors, product handling equipment, pick & place robots and lines,
electronic assembly systems, printing and measuring machineries,
electro-medical
instruments,
machine tools. This slim magnetic
scale system is designed to provide
both the absolute and the incremental information. Fitted with a
polymer ferrite composite media,
the magnetic scale is magnetised
with two tracks: a true absolute
track for position information and a
2-mm (0.08") pole pitch incremental track for speed feeback.
It has been narrowed to a width of
only 10 mm (0.39") while the measuring length has been lengthen up
to 8 m (26.2 ft). The scale is insensitive to dust, oil, grease, water and
most common chemical agents;
thus the measuring system is claimed to reliably operate in the most
aggressive industrial environments.
Also the dimensions of the sensing
head have been minimized; the
enclosure is very compact and slim
yet preserves its durability. It encapsulates the Hall sensors, the incremental sensor and the miniaturized
electronics and guarantees IP67rated environmental protection
along with immunity to contaminants as well as interferences.
By virtue of the non-contact operation SMA is virtually wear and
maintenance-free and ensures
unparalleled reliability over time.
The new advanced sensor produces
high resolution up to 1 µm and
enables velocities up to 7 m/s
(23 ft/s).
The encoder delivers absolute information through the BiSS-C or SSI
interface and the incremental
information through the NPN o. c.
output circuit. SMA encompasses
only first-rate components and
high-flex cables especially suited
for use in cable drag chains, tested
for more than 1 million cycles.
