3 Product Features
The EMIX2 is an incremental magnetic length measuring system. The sensor technology and translator circuit are
placed in the same small housing. The magnetic tape can also be fixed into a guiding rail by using the provided
adhesive tape. The EMIX2 can be installed up to a maximum distance of 0.8 mm to the magnetic tape.
Overview of features:
Direct contactless measurement
The distance between sensor and measuring tape can vary between 0.1 and 0.8 mm
Measuring length theoretical unlimited
High resolution of 0.01 mm
Repeating accuracy +/- 0.01 mm
Very robust against pollution
3.1 Functional Principle
The basis of the magnetic incremental encoders consists of a scanning technology, which scans the north and
south poles on the coded magnetic tape and produces a single Sine/Cosine wave for each pole.
The complete sine/cosine signal process is interpolated electronically. Depending on refinement of the interpolation, together with the pole distance of the magnetic tape, the resolution of the measuring system is determined.
The magnetic tape ( 4.4) has a pole pitch of 2 mm. A special evaluation electronic (translator) processes the
sine/cosine wave into square output signals from the signal information of the magnetic tape. These square
signals are equivalent to conventional optical rotary- or linear encoder outputs.
