SICK (www.sick.com) has unveiled a robust, absolute multiturn encoder that offers the new A3M encoder – a 14-bit sigleturn and 17-bit multiturn or a total of 31-bit output. Integrated with a Profibus output, the encoder features absolute encoders that are native to it, even without an internal power source.

Featuring internal electronics that are resistant to condensation and contamination, the new A3M is ideal for use in outdoor applications and harsh environment. Based on the design of magnetic technology that utilizes few moving parts, the new encoder’s advance versions can communicate through the DP V2, wherein Profibus can be directly used by motion control applications instead of a secondary motion control bus.

The new encoder’s conformal coating for resistance against a high IP rating and condensation makes it suitable for outdoor applications such as cranes and outdoor warehousing systems. The advanced models of the A3M60, which provides the DP V2 protocol, can be utilized in motion control applications where fast cycle times and speed are very important.

Aside from bag forming, palletizers, labeling, filling, sealing, and folding machines, the A3M60 can also be used in collision avoidance and position control applications. Other typical applications where the new encoder can be used include AGVs, assembly machine, welding and paint spraying robots.

The A3M60 is also suitable for the various needs of general manufacturing applications where a Profibus fieldbus network is utilized.
