Do not wear rings, necklaces or other jewelry.
PROTECTIVE GLOVES
…for protecting the hands against abrasion, wear and other injury of the skin.
PROTECTIVE HELMET
…for protection against injuries of the head.
4.4 Demounting and Disposal
Unless acceptance and disposal of returned goods are agreed upon, demount the device considering the safety instructions of this manual
and dispose it with respect to the environment.
Before demounting, disconnect the power supply and secure against re-start. Then disconnect the supply lines physically and discharge
remaining energy. Remove operational supplies and other material.
Disposal: Recycle the decomposed elements: Metal components in scrap metal, Electronic components in electronic scrap, Recycle plastic
components, dispose the remaining components according to their material consistence.
Local authorities and waste management facilities provide information about environmentally sound disposal.

5 Product Features
The GMIX1A is a magnetic, incremental linear encoder for measurement of lengths and distances. The evaluation electronics are
housed in a separate box where the square wave output signals
are indicated via LEDs. Another LED is used to indicate the operating status.
Various settings can be made via a 6-pin DIL switch, which is
located in the evaluation box (see 8.1):
The output levels (TTL Line driver or HTL push / pull)
The configuration of speed monitoring VMAX
The resolution of the measuring system
5.1 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 MB20-50-10-1-R has a pole pitch of 5 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.

The output level can be switched between HTL and TTL via the internal DIL switch.
The index pulse Z is only output as a single channel (not inverted).
