Rotary encoder for robotics, automation

Heidehain EBI 1135 absolute inductive rotary encoder can provide feedback for position and speed control of servo drives.

03/20/2012


Heidehain's New Rotary EncoderIn robotics and automation technology, rotary encoders and resolvers serve on servo drives as feedback systems for position and speed control. 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 fits this bill.

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 13 mm and a housing outside diameter of only 37 mm, 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 EBI 1135 rotary 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 14 V 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.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
