Sturdy Rotary Encoder New from Heidenhain
Inductive scanning rotary encoder.
Schaumburg, IL — An increasing number of applications require multiturn versions of absolute encoders that are low in cost and as sturdy as resolvers, but with features beyond what resolvers can provide. Heidenhain's new EBI 1135 absolute inductive rotary encoder nicely fulfills this need.

Within the new EBI 1135, the fast EnDat 2.2 pure serial interface is used for transmission of a high-resolution absolute position value to improve transmission reliability, in particular in environments with high electromagnetic noise potential (e.g. on welding robots). With an overall length of less than 13mm and a housing outside diameter of only 37mm, the EBI 1135 is one of the world's smallest rotary encoders and is therefore predestined for use on highly dynamic servo motors with small dimensions for automation technology and industrial robots.

The encoder attains a total resolution of 34 bits (singleturn: 18 bits, multiturn: 16 bits). Its modular design without ball bearing and a battery-buffered revolution counter permit very compact dimensions.

The new encoder distinguishes itself in particular with optimized inductive scanning together with a sturdy design. This becomes possible in particular because it functions without optical components (glass scale, LED), which can be handicapped by contamination, vibration, shock and high temperature. The higher permissible axial scanning gap tolerance of ±0.3 mm, the expanded voltage range of 3.6 to 14V and, compared with multiturn scanning with a mechanical transmission, the greatly expanded multiturn value range of 65,536 distinguishable revolutions increase the reserves in the application available to the customer.
