Robust CANopen Singleturn Encoder for Outdoor Applications

The new absolute single turn encoders with CANopen interface require little installation space due to a length of only 35 mm. Based on double-sealed ball bearings and a pressed-on housing which minimizes the sealing surface they provide IP67 protection. They are therefore suitable for use in rugged environments, such as in outdoor applications or in mobile machines. The encoders use a tried and tested optoelectronic scanning method (based on the concurrent analysis of a Gray code pattern and two incremental tracks) to record position values. They provide a maximum resolution of 15 Bit per revolution. Node address and Baud rate can be adjusted via SDO telegrams, moreover, counting direction, preset value and resolution per revolution can be programmed via the CAN bus. All parameters can be stored in the encoder's non-volatile memory. The devices are connected via a 5-pin micro-style connector.
