Both the low cost EM58 series and the high resolution HS58/HM58 series from Lika Electronic are available with Profinet IO interface today. PROFINET is the 100% Ethernet compatible open standard for Industrial Ethernet. Spreading increasingly and rapidly at all levels, Ethernet industrial technology enables improved performances and allows to meet efficiency and productivity requirements in any complex industrial system. Real time communication, deterministic synchronization, high speed up to 100 Mbit/s full duplex over long distances, flexible network topologies, complete diagnostics, IT integration are among the key benefits. Profinet IO encoders from Lika Electronic fully comply with the Encoder Profile Specifications V4.1 version 3.162 based on the PROFIdrive profile. Furthermore they fulfill the requirements of the Application Classes 3 and 4, thus they support both the RT real-time transmission mode and the IRT isochronous real-time mode to meet precise and deterministic data exchange needs (jitter less than 1 µs and cycle time down to 1 ms). The standard TCP/IP channel is used for parametrization, configuration and acyclic read/write operations. The most frequent network topologies can be implemented and even mixed together including Star, Line, Tree and Ring structures. The number of nodes is virtually unlimited. Profinet encoders support the standard telegrams 81, 82, 83 and 84: full scaling, preset, code sequence, position and velocity readout, diagnostic information etc. functions are implemented. EM58 is the low cost multiturn version offering 27-bit resolution (8192 cpr x 16384 rev.). H- high resolution series comes in both singleturn (18-bit resolution, 262144 cpr) and multiturn (30-bit resolution, 65536 cpr x 16384 rev.) versions. Mechanically they afford standard 58-mm flange diameter housing with both hollow (Ø 14, 15 mm) and solid (Ø 6, 8, 9.52, 10, 12 mm) shafts. Capable of 6.000 RPM and working temperatures between -25°C and +85 °C (-13°F +185°F) they provide IP65-rated protection. M12 D-coding connector and AWG 22, cat. 5 cable outputs are available: they comply with Profinet standards and allow for simplified and safe connectivity, thus saving time and money whilst minimizing the risk of errors. LEDs for visual diagnostic information are further used. Ethernet family absolute encoders are also available with EtherCAT interface. Read more at .
