New Low Profile Encoders from HEIDENHAIN Perfect for Small Motors
These new encoders distinguish themselves not only by their short overall length but also by their modern opto-ASIC based photoelectric scanning with integrated interpolation. Thanks to the electrical output at TTL levels with differential signals, these encoders can be connected to almost all standard subsequent electronics for control of digitally controlled servo motors (up to edge lengths of 40 mm and 55 mm), and are useful in various applications in the Automation industry.
Currently available, the HEIDENHAIN ERN 1023 encoder has an overall length of 35.2 mm max and an IP 64 rating, making it especially useful in hazardous environments; the
HEIDENHAIN ERN 1123 encoder has an overall length of 30.3 mm max and an IP 0 for general use.
Both encoders have mounted stator couplings and blind hollow shafts. Choice of appropriate commutation signals is available to the buyer as the amount depends upon the number of poles of the motor to be controlled.
