ERP 1000 angle encoders from Heidenhain suitable for measurement, positioning

Heidenhain has introduced the ERP 1000 series of angle encoders, which the company says offer high resolution, high speed, and high contamination resistance for measurement and positioning applications.

Comprising a glass disk bonded to a hub and a scanning unit that scans the fine graduation on the surface of the disk, the encoders are offered with four different disk and segment sizes. The disks can have up to 63,000 lines with accuracy to +/-0.9 arc-seconds and up to 2,600 RPM. A reference mark is included, and multiple scanning units could be used to increase accuracy further.

The scanning units also have the new custom ASIC HSP 1.0, which forces the stabilization of the signals through an advanced LED brightness control. When the scanning unit detects contamination, the LED intensity is increased to help increase the reflectivity and therefore reducing amplified noise.
