An encoder is a position sensing device. They are used to sense rotary motion and they provide feedback, via an electrical signal, to a processor, controller, or computer. Therefore they are used in automated machinery and test systems in conjuction with friction and measuring wheels, ball screws, timing pullies, rack and pinion actuation, etc..

just about anything you can think of that combines motion and automation

Rotary encoders serve as measuring sensors for rotary motion, and for linear motion when used in conjunction with mechanical measuring standards such as leadscrews. Areas of application include:

• Electrical drives
• Machine tools
• Printing presses
• Woodworking machines
• Robots and handling devices

HEIDENHAIN rotary encoders convert rotary motion to electrical signals by photoelectrically scanning DIADUR circular graduations. The measuring signals are evaluated either in numerical controls (NC) and programmable logic controllers (PLC), or simply in a digital position display unit. Thanks its a wide range of mechanical and electronics features, the HEIDENHAIN rotary encoder program offers a the suitable rotary encoder for virtually any application - from simple positioning tasks to the highly dynamic control of electrical drives. The rotary encoders of the ERM product family feature magnetic graduations on drums.

ECN 1313 by HEIDENHAIN

Compact absolute rotary taper shaft encoder with integral bearing and mounted stator coupling with 1Vpp and EnDat output and IP 40 protection

HEIDENHAIN's ECN rotary encoders have an integral bearing and a mounted stator coupling. The encoder shaft is connected directly to the measured shaft. During angular acceleration of the shaft the stator coupling must absorb only that torque resulting from friction in the bearing. ECN rotary encoders therefore display high dynamic performance and high natural frequencies.


Incremental signals - 1 VPP
Line count - 512 or 2048
Data interface - EnDat
Absolute position values - 8192 (13 bits)
Power supply - 5V
