Posital announced new models of its IXARC rotary encoders with housings that are 27 millimetres long.
This reduced length is combined with a diameter of 36 mm. The radial cable entry and shaft seal have protection ratings of IP65, ensuring reliable operations under wet and dirty conditions. A wide variety of flange and shaft configurations are available.
The compact encoders are based on Posital’s magnetic measurement technology. Both incremental and single-turn absolute versions are available. Incremental variants are programmable: resolution can be set anywhere from one to 16,384 pulses-per-turn in software without requiring any changes to the mechanical properties of the devices.
Similarly, pulse direction and the output driver, either Push-Pull (HTL) or RS422 (TTL), can be reset through software updates. Changes can be made in the shop or in the field using Posital’s UBIFAST programming tool. Absolute versions have resolutions of up to 16-bit and are available with analog, CANopen or SSI interfaces.
