Series 4000 angle encoders from Heidenhain Corp. is available in seven diameters for use on rotary systems, spindles, and other motors.

Schaumburg , IL —Expanded Series of ERA 4000 angle encoders from Heidenhain Corp. is intended for use on a wide range of rotary motion systems, spindles, and other motors. Product family is said to offer high accuracies, multiple easy and stable mounting methods, and reference marks that can be distance-coded to provide semi-absolute positioning.

ERA 4x80 is mounted using a centering collar method. Low-profile encoder system requires no centering methods; precision machined centering collar mates with the precision-machined shaft of the motion system. ERA 4x81 is a weight-reduced T-profile version mounted using the 3-point centering method. The three centering marks are placed on the ring at 120-deg intervals to point to the exact center of the ring while on the manufacturing device; then the encoder gratings are written onto the ring so that when the centering marks are used during installation, non-circular geometries of the ring and gratings are eliminated. ERA 4x82 uses the 3-point centering method for installation and has the highest accuracy of the series.

All versions use the same scanning unit per diameter and have a movable faceplate to allow the best signal possible to be obtained from small, easy adjustments. Faceplate maintains position even under severe machine vibration. Series comes in seven diameters from 52.65 to 331.31 mm and grating periods of 20, 40, or 80 microns. Electrical output is available in 1 V (peak-to-peak) analog interface.
