Edited by Zak Khan || It may seem as though linear encoders and rotary encoders have strictly defined (and maybe even mutually exclusive) applications. Prevailing logic is that linear encoders track linear motion and rotary encoders track rotating shafts — but this isn’t always the case. Some motion designs can use linear or rotary encoders, […]

Linear encoder types — and parameters for selection
Linear encoders monitor linear movement and provide position feedback in the form of electrical signals. In servo driven systems, linear encoders supply the precise position of the load, typically in addition to the speed and direction feedback provided by the motor’s rotary encoder. For stepper driven systems, which typically operate in open-loop mode with no position […]
Fagor Automation introduces Nanometer High Resolution Linear Encoders
Fagor Automation Corporation has developed and introduced a new line of Linear Encoders capable of 50 nanometer resolution. Designed for high performance markets such as precision grinders and the EDM market. In addition, due to the ability of the new product capability of achieving nanometric measurements directly from the encoder without the need for electronic […]
Getting accuracy out of machine tools: Linear encoders eliminate errors from thermal drift
Linear encoders help eliminate errors from thermal drift. || Dr. Jens Kummetz, R&D Manager, HEIDENHAIN, Traunreut, Germany Thermal accuracy of machine tools is becoming increasingly important considering the strongly varying operating conditions in manufacturing. Especially with small production batches that require constantly changing machining tasks, a thermally stable condition can’t be reached. At the same time, […]
New Slim Linear Encoders from RSF
Schaumburg, Ill. – RSF, whose sister company is HEIDENHAIN Corporation, introduces a new slim profile linear encoder series MSA 700 and 800 for metrology applications requiring protection from contamination. The encoders feature generous mounting tolerances, low level backlash and optimized thermal behavior. Typical applications include optical comparators, and video and vision systems. Central to the design […]
