HEIDENHAIN: Angle Encoders (ERP 880/4080/8080 Series)

The term angle encoder is typically used to describe encoders that have an accuracy of better than ± 5“ and a line count above 10000. In contrast, rotary encoders are encoders that typically have an accuracy of more than ± 10“. Angle encoders are found in applications requiring precision angular measurement to accuracies within several arcseconds.

Examples:

Absolute angle encoders without integral bearing

The angle encoders without integral bearing (modular angle encoders) ERP, ERO and ERA consist of two components—a scanning head and a graduation carrier, which must be aligned with each other during mounting. The eccentricity of the shaft as well as installation and adjustment therefore have a decisive effect on the achievable accuracy.

Modular angle encoders are available with various graduation carriers

Angle encoders without integral bearing are designed for integration in machine elements or components. They are designed to meet the following requirements:

Because angle encoders without integral bearing are supplied without enclosure, the required degree of protection must be ensured through proper installation.
