Introduction
In many manufacturing and production processes they are indispensable as reliable transducers to ensure precise positioning. They convert rotary movement into digital signals. Linear measurement is also possible in conjunction with rack and pinion or measuring wheels. Encoders use the wear-free photoelectric detection. A pulse disc firmly attached to the shaft ensures this detection.

Absolute encoders provide an absolute numerical value for each angular position. This code value is available immediately after power is applied. This ”absolute” value makes a reference procedure like the one required for the incremental encoder unnecessary. Absolute encoders are used wherever angular positions have to be allocated to a certain value and where the detection of the present position is absolutely necessary in the case of a power failure.
ifm electronic
ifm electronic gmbh is one of the leading manufacturers of automation technology world-wide. More than 3,000 employees in more than 70 countries develop solutions for 80,000 customers in the manufacturing industries. By optimising technical processes in the automotive, chemical and cosmetics industries or in environmental technology and automation of buildings ifm electronic has consistently set new standards and thus ensures tomorrow's production processes.

The family-run company with headquarters in Essen started with the invention of inductive proximity sensors in 1969. The German production in Tettnang on Lake Constance has ensured brand quality right from the start. Today "efector" stands for position and fluid sensors, object recognition, diagnostic and identification systems. The brand "ecomat" is synonymous with networking and control systems. In 2007 ifm made a turnover of more than € 410 million with above-average product quality, exceptional innovations and consistent close contact to the customer.
