ENCODERS

Rotary encoders All positioning tasks in factory automation and con- struction require current and precise position values to monitor motion activity. Absolute rotary encoders mark every step of movement by a unique digital signal. This ability to assign distinct and exact values to linear and angular positions at any time has made absolute rotary encoders a pivotal means of connection between mechanics and the control system.In comparsion to other systems for angle measure-ment like inclinometers, rotary encoders provide a comparably high measuring frequency and a con- stant precision over the full measuring range, which extends beyond 360°. They determine angle values by scanning the posi-tion of a shaft within the sensor unit. Given the diversity of potential applications, there is a need for different mechanical interfaces and coupling systems. Also, various interfaces for connecting encoders to control systems have been established in the market. Considering possible combinations of functional sensor specifications with mechanical and electrical interfaces POSITAL’s current product lines are all based on a modular design.The appropriate choice of a rotary encoder for anapplication depends on the kind of motion, the form of motion transmission, the operating conditions, the necessary resolution and the electrical inter- faces involved.
