AMOSIN® – General Information

A new powerful generation of linear and angular measuring systems – unlike any optical or magnetic encoder, has been developed based on our AMOSIN ® Inductive technology, where high-precision is achieved by scanning stainless steel photolithographically etched structures with sophisticated inductive sensors and processing the signals with proprietary integrated electronics (ASIC).

The AMOSIN ® length measuring systems can be supplied as open non-contact encoder or as a non-contact guided linear guideway rail as an alternative to encapsulated (extrusion) optical encoders.

The angle measurement systems are Ring Scales with open hollow large bore thru holes and have non-contact inductive scanning of the graduation pattern ring with no coupling or mechanical connection, for easier application to rotary feedback applications.. The AMOSIN ® systems offer high resolutions up to 0,125 microns on the circumference and accuracies to ± 3 µm / m, with an IP 67 rating that is extremely resistant to environmental influences such as dust, moisture and have an extremely high shock and vibration resistance.

Our high accuracy inductive angular encoders are comparable to the opto-electronic measurement systems in accuracy and resolution, due in part to the manufacturing process of the rigid stainless steel scale tape measure that provides an excellent sensor signal output with sine wave accuracy deviations of <0.1% (harmonic content as a measure of the achievable interpolation within a period of pitch). The measuring principle is described below. The measuring system does not include any magnetic parts and is, in contrast to magnetic measurement systems, totally resistant to any kind of electromagnetic interference and has no hysteresis.

Following the principle of the data acquisition of the position measurement systems are divided into the following categories:

Incremental measuring systems
Absolute measuring systems
The wide range of applications of AMOSIN ®-length and angle measuring systems covers a wide range of applications from extremely precise positioning in quality control machines, assembly machines, metalworking machine tools, to direct driven linear motor axes where high dynamic stiffness is required.
