Safety relevant equipment must be designed to prevent any damage to persons or to the environment in case of malfunction of the control mechanism or any components. This applies to cranes, lifts, theatre installations and similar constructions.
Sensors with PROFIBUS interfaces must meet these requirements. Therefore the TWK rotary encoders of the CRD/S series have recently been designed according to the PROFIsafe profile for safety technology to the PNO standard No. 3.920. The protocol meets the DP slave class 2 functionality to PNO No. 3.600. The resolution is 13 bits/360°, the maximum measuring range is 4096 revolutions. To guarantee a fail safe operation, a F-CPU master, e.g. Siemens S7 Distributed Safety must be used.

Magnetic Encoders
As market conditions become increasingly competitive, magnetic encoders are seen as a promising incumbent, offering engineers an encoder solution that is small, robust, yet, priced significantly lower than existing absolute encoders in the market today.
A magnetic encoder typically uses Hall effect or magneto-resistive (MR) effect to sense positional information. Avago's magentic encoder with integrated Hall sensors requires a permanent magnet that is firmly mounted on the rotating shaft of a motor. A magnetic encoder operates on a non-contact basis. Thus, mechanical wear is not a consideration.
Avago’s magnetic encoder solution is high performance, designed for use in a wide range of industries that includes industrial and office automation, as well as, consumer applications. Its typical applications includes test and measurement equipment, surveillance and security, printers, fax machines and copiers, white goods and appliances, cable and satellite dish, toys and games, and much more.
