Angle measurement system

Angle professional encoders
The term angle encoder is typically used to describe encoders that have an accuracy of better than ± 5" and a line count above 10000. These devices are used in applications such as NC manufacturer of rotary tables, swivel heads of device tools, dividing apparatuses, high-precision angle measuing tables, precision devices in angular metrology, professional antennas and telescopes.

Shaft encoders
Rotary encoders from HEIDENHAIN serve as measuring sensors for rotary motion, angular velocity and also, when used in conjunction with mechanical measuring standards such as lead bolts, for linear motion. Application areas include electrical motors, machine tools, professional printing machines, woodworking machines, textile machines, professional robots and handling devices, as well as various types of measuring, testing, and industrial inspection devices.

With incremental angle encoders and rotary encoders, the current position is determined by starting at a datum and counting measuring steps, or by subdividing and counting signal periods. Incremental encoders from HEIDENHAIN feature reference marks, which must be scanned after switch-on to reestablish the datum. Incremental rotary encoders with commutation signalssupply the angular shaft position value - without requiring previous traverse - with sufficient accuracy to correctly control the phases of the rotating field of a permanent-magnet three-phase motor.
