Figure 1.1: Scheme of the METIRIO family encoders
In Particular the following specificaions are identical for the METIRIO Readhead and all other read-
head housing variants:
• Optical Specifications
• Electrical analog and digital specifications
• Alignment Tolerances
The METIRIO A1 comprises an aluminum housing with mounting threads, the integraded ME-
TIRIO Readhead, a cable with strain-relief and a connection plug. The METIRIO A1 can be further
integraded into taylored external housings, to match any mounting requirement.
An encoder consists of a readhead combined with a measuring scale. It is intended that the read-
head is connected to a motion controller which provides the power supply and is capable to inter-
pret and further process the encoder output signals. The readhead outputs analog incremental
and reference signals related to the relative displacement of the scale in the measuring direc-
tion. These signals have to be digitized and further processed by the motion controller in order to
perform closed-loop movement. The motion controller is not part of the METIRIO product family.
Compatible motion control systems are for example the controllers of the SmarAct MCS 2 family.
METIRIO is an analog 1D encoder.
