Incremental Rotary Encoders suit small servo motors.

Press Release Summary:

Measuring 35 mm in diameter, HEIDENHAIN 1000 and 1100 Series feature block commutation tracks and opto-ASIC based photoelectric scanning with integrated interpolation. HEIDENHAIN 1023 has overall length of 35.2 mm and IP64 rating, making it useful in hazardous environments, while HEIDENHAIN 1123 encoder has overall length of 30.3 mm and IP0 rating for general use. Both models feature mounted stator couplings and blind hollow shafts.

Original Press Release:

New Low Profile Encoders from HEIDENHAIN Perfect for Small Motors

SCHAUMBURG, IL - For high quality speed control at competitive prices, HEIDENHAIN Corporation now introduces new low profile incremental rotary encoders with block commutation tracks, especially suitable for use in small-dimensioned servo motors. These new rotary encoders of the HEIDENHAIN 1000 and 1100 series come equipped with an industry-standard 35 mm housing diameter.

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 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 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.

More information about the new low profile ERN encoders is available by clicking on HEIDENHAIN catalog "Encoders for Servo Drives" (page 42) or by contacting HEIDENHAIN at (847) 490-1191 or HEIDENHAIN CORPORATION, 333 E. State Parkway, Schaumburg, IL 60173. HEIDENHAIN can also be accessed directly via the Web at

HEIDENHAIN CORPORATION is the North American subsidiary of DR. JOHANNES HEIDENHAIN GmbH, a leading international manufacturer of precision measurement and control equipment.
