Absolute encoder with Power over EtherCat

Baumer: EtherCAT as an Ethernet solution is conquering all levels of industry automation, from process control level down to field and sensor level. Power over EtherCAT enables fieldbus signal transmission and power supply using a single cable. The expensive and often troublesome double cabling needed so far is no longer necessary. The considerable cost advantage is associated with another effect: Supplementary mains units are no longer required either. Power over EtherCAT is particularly suited for places difficult to access or where a tangle of cables would hamper. Furthermore, central uninterruptible power supply is improving the failsafe performance of the connected devices. Now also encoders benefit from these technology enhancements.

Baumer has enhanced their dependable and practice-proven EtherCAT absolute encoder ATD 2B with the Power-over- EtherCAT functionality. The expensive and often troublesome double cabling required for fieldbus signal transmission and power supply is no longer necessary. By the extremely short cycle time of only 62,5 μs the encoder sets new standards in realtime communication between drives and control systems. Errors resulting from delayed feedback of position data now finally belong to the past. The optical absolute encoder utilizes a 14 bit singleturn resolution, as (gearless) multiturn encoder it features a 30 bit resolution. In other words, a resolution of 16.384 steps per turn enables up to 65.536 turns. The encoder comes in a hollow shaft design (shaft diameters 10, 12 or 14 mm). With an outer diameter of 58 mm and only 63 mm in length the encoder is particularly suited for confined installation space. Capable of 6.000 ppr maximum speed and operating temperatures ranging from -20 to +85 °C the encoder provides IP65 protection and masters reliably tasks in rather harsh environments without any problems.
