Rotary encoder with Profinet communications interface
Posital has added an optional Profinet communications interface to its range of explosion-proof Ixarc rotary encoders. These devices have been designed to comply with ATEX/IECEx directives for Category 3 electrical products and are suitable for Zone 1 and Zone 21 conditions (potential exposure to hazardous levels of explosive gases and dust concentrations). The encoders are designed for applications such as oil and gas facilities, underground mines, chemical plants, milling operations and grain-handling facilities.
Posital’s ATEX-certified encoders are built with aluminum or type 316L stainless steel housings that are designed to contain any electrical hot spots or sparking and to provide environmental protection ratings of up to IP67. The encoders can deliver up to 16-bit resolution in single-turn configurations or 14-bit resolution for multi-turn models. This technology ensures that position measurement integrity is maintained even if movement occurs when system power is unavailable. No backup batteries are needed, reducing maintenance costs.
Ixarc Profinet encoders have an integrated IRT switching capability that adds flexibility when it comes to designing the network topology. A built-in bootloader enables in-situ firmware updates, while six diagnostic LEDs simplify setup and troubleshooting. Ixarc encoders are also available with a removable connection cap, which allows users to choose between axial or radial cable exits.
