5 Product Features
The length measuring system LMIX22 bases on the proven LMIX encoder system. The system extends the existing
LMIX product series and offers two considerable advantages:
The resolution can be freely selected ( 0)
The sensor is also available with a unique reference pulse ( 5.1 resp. 5.2)
Overview of features:
Distance between sensor / magnetic tape up to 2.0 mm
Differential HTL or TTL Line Driver Outputs
Various resolution with 4 edge triggering available (order designation)
Repeat accuracy +/- 1 increment
Small sensor with integrated evaluation electronic (translator)
Speed proportional output of square-wave signals
Periodic index pulse every 5 millimeters (standard version) or
optional reference pulse output (versions 007 and 027) available
Despite the small dimensions the evaluation electronic (translator) is integrated in the sensor head. Optionally, a
vertically mountable LMIX22 variant is available. This must be specified as option “L” with the order ( 12.1).
Please note the following when ordering option “L”:
The position of the internal sensor board is displaced by 90°. So a horizontal mounting, respectively sensing is
no longer possible!
Further information about the mounting positions:
Standard: horizontal installation ( 7.3.2.1)
Option L: vertical installation ( 7.3.2.2)
5.1 Version LMIX22-007
Instead of a periodical index pulse (channels Z / Z‘), a single reference pulse (channels R / R‘) occurs at the
position where the magnet angle MW-007 (accessorial part 12.5) is installed. For more information refer to
sections 7.4 and 8.2.
5.2 Version LMIX22-027
Instead of a periodical index pulse (channels Z / Z‘), a single reference pulse (channels R / R‘) occurs at a desired position of the magnetic tape ( 8.3). In this case, a dual track magnetic tape (type MB20-50-10-2) must
be used. The desired reference pulse position can be ordered by using the type designation of the magnetic
tape ( 12.3). See also example 8.3.

The channels A and B are phase

The index pulse output occurs
periodically every 5 mm or optionally as a free definable reference pulse (R / R’).
5.3 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.
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.
The translator circuit of the LMIX22 measuring system is already integrated in the sensor head.

6.1 Identification
The type label serves for the identification of the unit. It is located on the housing of the sensor and gives the
exact type designation (=order reference, see type designation) with the corresponding part number.
Furthermore, the type label contains a unique, traceable device number.
When corresponding with ELGO always indicate this data.
