March 3, 2015 - POSITAL introduced IXARC Hybrid magnetic encoders that combine incremental and absolute rotation measurement capabilities in a single, compact and highly robust package. Absolute encoders provide a control system with an accurate report of the rotational angle and rotation-count at a specific point in time, which makes them ideal for many machinery positioning tasks. Incremental encoders provide a signal pulse each time the encoder shaft rotates by a specified angle. Their excellent dynamic response makes them a good choice for monitoring rotational speed and direction. Because the new IXARC hybrid encoders are based on magnetic measurement technology, they offer a combination of accuracy, shock/dust/moisture resistance and compact size.
IXARC hybrid incremental + absolute rotary encoders have communications interfaces that support both measurement modes: RS 422, HTL or TTL for incremental readings and SSI for absolute measurements. Available multi-turn versions can count up to 64,000 revolutions while incremental measurements have resolutions as high as 16,384 pulses per revolution.
Like other POSITAL sensors, the IXARC hybrid incremental + absolute 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 – up to IP67.
“Combining both measurement capabilities in a single device provides control system designers with extra flexibility,” underlines POSITAL product manager Chintan Doshi. “Moreover, the incremental signal can be used as a ‘heartbeat’ that confirms that the sensor is functioning normally.”
