POSITAL’s new generation of IXARC precision magnetic absolute rotary encoders are now available with BiSS C communications interfaces. Encoders with this interface are ideal for commutation and position feedback in BLDC servo motors. Moreover, their excellent performance characteristics, compact size (36 mm diameter, 32 mm high), and low energy requirements make these IXARC encoders excellent candidates for complex, multi-axis motion control applications in areas such as robotics and medical equipment.
IXARC encoders with the BiSS C interface feature POSITAL’s latest TMR position sensing technology and microprocessors. These upgrades improve both resolution (up to 19 bits), dynamic response (up to 12,000 RPM) and energy efficiency. Multiturn variants feature a 32-bit rotation measurement range (over two billion revolutions). Rotation counters are self-powered, using Wiegand energy-harvesting technology. This eliminates the need for backup batteries or gear drive systems, significantly reducing maintenance requirements.
BiSS C (Bidirectional/Serial/Synchronous Continuous) is a high-performance interface that supports real-time communications between control devices and sensors/actuators in motion control systems. The interface also allows the controller to set operational parameters in slave devices. Communication is based on point-to-point RS-422 connections with the possibility of daisy-chaining several devices together for more efficient cable layouts. The BiSS C interface uses the same cabling components as the older SSI interface, simplifying upgrades. BiSS interfaces are based on non-proprietary standards, with support and licenses available at no charge from the non-profit BiSS Association e V.
Like other POSITAL encoders, the BiSS C enabled products are available in a wide range of mechanical configurations, with multiple options for housing and flanges, shaft type, and level of environmental protection. Their 36 mm housings will fit into the same mounting footprint as popular Size 15 resolvers. Unlike resolvers thpugh, IXARC encoders offer multiturn absolute digital position measurements, eliminating the need for an A/D converter.
