Precise.
Mechanics, sensing unit and electronics of OptoPulse EIL580
encoders are ultra precise. The excellent signal quality will
substantially enhance productivity and the level of control in your
application.
Precise mechanics
Precision-manufactured mechanics with two high-quality, pre-
loaded bearings is the basis for optimum radial and axial runout
properties. The slotted hollow shaft fi rmly adheres to the motor
shaft, will reduce vibration and allows for higher shaft toleran-
ces.
Precise sensing technique and electronics
The innovative optical sensing technology ensures ultimate
accuracy and constantly high signal quality t hroughout the entire
temperature range from -40 to +85 °C.
The heart is a monolithic OptoASIC with high integration density,
especially conceived for use in encoders. The code disc with
high-precision increments provides reliable measuring results
without any interpolation errors. The limited number of discrete
components adds on reliability and decisively improves shock
and vibration characteristics. The encoder electronics provides
an overall-immunity against strong magnetic fi elds which for
example prevail at magnetic brakes.
