Optical encoders with an EtherNet/IP interface
Cologne – POSITAL's new OPTOCODE models are the first absolute encoders with an Ethernet/IP interface on the market. The company thereby expands its wide range of bus interfaces, providing a suitable encoder line for almost any application. The units feature an Ertec200-based platform and reach cycle times of less than 10 ms. The very compact design of the encoders is another outstanding characteristic: the units, which have a diameter of merely 58 mm, do not require a connection cap. Unlike DeviceNet models, they also do not require terminating resistors or switches for address allocation and Baud rate adjustment. Being shorter than most Industrial Ethernet encoders on the market, they can be used in applica-tions with limited installation space. They feature an integrated switch which facilitates wiring and allows users to save expenses for external hardware. Just like in DeviceNet encoders, EDS files ensure easy configuration. Further equipment includes two M12 connections for data transfer, one M12 connection for voltage supply, and six LEDs for bus diagnosis. The IP67 protected devices can be used in rugged industrial environments. Like all OPTOCODE encoders, the EtherNet/IP models use a proven opto-electronic scanning method to record position values. The single-turn sensor provides a resolution of 16 bit per revolution. Additionally, a maximum of 16.384 revolutions (14 bit) can be registered in multi-turn mode, thereby covering a measuring range of 30 bit. All OPTOCODE encoders operate without backup batteries and instantly provide current absolute position values without referenc-ing even after power failure.
