ENI11HD Series Heavy-Duty Incremental Rotary Encoder [Movie]

The heavy-duty incremental rotary encoders of the ENI11HD series guarantee reliable measurement results in harsh environments. Versatile in many applications, the encoder is also used in speed feedback for large asynchronous motors. Its exceptionally sturdy design withstands extreme environmental conditions, such as heat, cold, dirt, constant vibrations, severe shocks, and electromagnetic interference.

The ENI11HD heavy-duty incremental rotary encoders offer comprehensive protection against shaft currents. The series is insensitive to electromagnetic emissions. Its extreme resistance to vibrations and shocks makes this a highly resilient component that guarantees high process reliability and minimal failure risk. Its 4 × 90° swiveling junction box simplifies handling and allows cables to be installed quickly in the field.


  • Resistance to shaft currents increases bearing life
  • Flexible installation with four-position connection access
  • Robust construction provides extreme shock and vibration resistance
  • High degree of protection, IP66/IP67 and IP69K, for use in harsh applications
  • Reliable operation under very high EMC conditions
