Preliminary information
This guide is designed to provide the most complete information the operator needs to correctly and
safely install and operate the linear encoders with guided profile of the
SMAG series
that provide
SSI
interface
and Gray output code.
The SMAG sensors are engineered to measure linear displacements in industrial machines and
automation lines.
The measuring system consists of a magnetic tape mounted on a rigid profile and a magnetic sensor. The
tape has a coded sequence of poles; the distance between two poles is referred to as “pole pitch”. The
sensor moves along the magnetic tape (or, on the contrary, the magnetic tape is moved under the
sensor), thus the sensor detects the displacement and issues an output signal equivalent to the one
generated by an absolute encoder or an optical linear scale.
The sensor must be compulsorily paired with the
MTAG magnetic tape
. The measuring length is from
115 mm (4.528”) to 570 mm (22.441”), see the order code.
For technical specifications please refer to the product datasheet.
To make it easier to read the text, this guide can be divided into some main sections.
In the first section (from chapter 1 to chapter 3) some general information concerning the safety, the
mechanical installation and the electrical connection as well as tips for setting up and running properly
and efficiently the SMAG linear e MTAG are provided.
In the second section, entitled
SSI Interface
(chapter 4), you can find detailed information on the SSI
interface.
