Other applications well suited for our inductive measuring encoders can be for multi-head position feedback for machine tool, Pan and Tilt Camera.

The IP67 rating which is the degree of protection that is insensitive to contamination, allows our encoders to not only offer precision but also robustness.

AMO – angle measuring encoders are available for outside scanning and inside scanning. Reference marks are integrated in the measuring ring and can be configured with just one, multiple, or distance coded.

There is an extremely wide range of applications for the AMO angular measuring encoders, ranging from precision rotary tables, medical applications, high-dynamic torque motors, spindles, to the toughest applications in the machine tool field, where precision and robustness are required.

For high accuracy applications, we recommend the angular measurement encoders with multi-head scanning.

Ring scales

Stainless steel ring scales or ring scales installed on hubs are available in a range of sizes, with hubs available in standard sizes. Ring scales can be supplied in any diameter with the circumference an integer of the scale pitch. Custom shapes and sizes are available.

There are a series of rings on hubs available in standard diameters. Any customer specific diameter design from 80mm to any size is possible. All flanges and measuring rings are offered in different accuracy classes.

Scanning head

The scanning heads are IP 67 rated and have a high degree of protection and immunity to contamination.

AMO offers the miniature scanning head with external electronics and heads with integrated electronics. Outputs are TTL (RS422) or 1Vpp Sine Wave.

Typical applications

• Direct drive torque motors
• Rotary tables
• Rotary axes
• C-axis and 4/5 axes on machine tools
• Printing machines
• Sheet metal and machine tool machines
• Medical equipment
• Robotic
