POSITAL upgrades PROFINET interface for its IXARC encoder series.

POSITAL announced it has upgraded the PROFINET communications interface of its IXARC series of absolute encoders. The speed of the interface has been increased, reducing cycle time by a factor of eight (new:125μs). In addition, the company has added capabilities, including acceleration monitoring and over-temperature warnings. Output from the encoders can be scaled (amplified or reduced) to meet the requirement of the controller. The encoder interface also supports MRP (Media Redundancy Protocol) and MRPD (Media Redundancy for Planned Duplication).

POSITAL’s IXARC magnetic encoders provide up to 0.005° resolution, (16 bit), accuracy of up to 0.02° (14 bit) and dynamic response that rivals the best optical encoders. Multi-turn models have a range of up to 65,536 revolutions. IXARC encoders are available with multiple options for housing size and materials, flange configuration, shaft type and diameter, connection/wiring type and level of environmental protection. The upgraded PROFINET interface is also available for the widely used optical encoders group OCD.
