Page 67 Sturdy Rotary Encoder New from Heidenhain
Schaumburg, IL — An increasing number of applications require mul- titurn versions of absolute encoders that are low in cost and as sturdy as resolvers, but with features beyond what resolvers can provide. Heiden - hain’s new EBI 1135 absolute induc- tive 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 hous- ing 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 res-
olution 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 with- out optical components (glass scale, LED), which can be handicapped by

contamination, vibration, shock and high temperature. The higher permis- sible axial scanning gap tolerance of ±0.3 mm, the expanded voltage range of 3.6 to 14V and, compared with mul- titurn scanning with a mechanical transmission, the greatly expanded multiturn value range of 65,536 dis- tinguishable revolutions increase the reserves in the application available to
the customer. Contact: Heidenhain Corp., 333

New Horizons in Bond Testing
The Nordson DAGE 4000Plus is the most advanced bondtester on the market, representing the industry standard in bond testing.
Florence, KY — Ticona Engineering Polymers has extended its Vectra® portfolio of halogen-free liquid crys- tal polymers (LCP) to include a new family of high-flow, high-perform- ance thermoplastics for use in today’s electronic portable devices. Vectra FIT70 for compact cam-
era modules (CCM) and Vectra FIT72 for thin-wall connectors are 35 percent glass- and mineral-filled LCPs. Both new Vectra FIT LCP grades provide high flow and improved flatness and each is designed to meet specific customer requirements. The new family of high-flow
Vectra LCPs is already in use in CCM products for mobile handset camera applications from Hysonic Co. Ltd. in South Korea, a manufac- turer of electro-mechanical actuator systems for optical application devices.
Vectra LCP is widely used by
customers to make halogen-free, eco- friendly connectors, bobbins, switch- es and relays that meet Restriction of Hazardous Substances Directive (RoHS) and European Waste Electrical and Electronic Equipment (WEEE) directives. In addition, cus- tomers and original equipment man- ufacturers are striving to accelerate the production of green and safe products.
