IXARC Incremental and Absolute Rotary Encoder

POSITAL - FRABA Inc.

POSITAL’s heavy-duty IXARC incremental and absolute rotary encoders are built to stand up to extreme environmental conditions. Based on a housing design with a 25-year track record of surviving the toughest conditions, these devices are suitable for marine vessels, off-shore facilities, mines, cranes, wind turbines and other challenging locations.

These sensors feature extra rugged impact-resistant Type 316L stainless-steel or aluminum housings with seals rated to IP67. Other heavy-duty features include bearings that can stand up to high mechanical shaft loads (up to 250 N axial, 350 N radial) and the ability to stand up to high shock and vibration impact (200 g and 20 g respectively). A special shaft-lock mechanism protects the internal components of the encoder from damage due to extreme thrust loads on the shaft. An optional mechanical overspeed switch can provide an additional level of safety for equipment and operators by sending a warning signal to a motor control if the rotational speed of the shaft exceeds a pre-set limit. The operating temperature range for the heavy-duty IXARC encoders is -40° to 80° Celsius.

Like other POSITAL products, the heavy-duty IXARC encoders are available in a wide variety of configurations. Incremental versions have resolutions (pulses per revolution) of up to 2500 PPR, while absolute versions are available with 16-bit resolution (.005°). Multi-turn variants of the absolute encoders have measurement ranges as high as 16,384 revolutions (14 bit). Other resolutions are also available for both incremental and absolute encoders. Incremental variants are available with Push-Pull (HTL) or RS422 (TTL) communications interfaces, while absolute models can be provided with either CANopen or SSI interfaces. Dual-function models are available that provide both incremental and absolute outputs.
