Lika Electronic's SMAR4 absolute modular encoder is remarkably small: the PCB readhead is one of the smallest on the market and measures only a few millimeters. The SMAR4 combines an open PCB readhead with the MRA and RMU magnetic rings with axial or radial magnetization in a very compact assembly. The through bore of the rings ranges from 8 to 70 mm. This design can be easily integrated into high-performance, space- and weight-critical applications such as robotic joints, robots and cobots, humanoids, surgical robots, electro-medical and laboratory devices, and OEM equipment.
SSI and BiSS Interfaces
The construction is frameless and bearingless; the measuring system is not equipped with a shaft, bearings, flange, and housing. Operation is contactless and no components are subject to wear or mechanical fatigue. The operating temperature ranges from -25°C to +100°C. The SMAR4 is equipped with SSI and BiSS C-Mode interfaces. It offers a resolution of up to 20 bits (1,048,576 cpr). In addition, up to seven encoders can be networked in a daisy-chain configuration.
