February 20, 2014 - Leine & Linde releases model PHE 900 encoder, suitable for heavy equipment applications. It has a solid aluminum housing and bearing design for environments where shock, vibration and shaft loads are extreme. Hollow shaft designs up to 16mm are available. In addition, 17mm taper shaft or 20mm hollow-shaft with keyway are also standard offerings. Alternatively, an 11mm or 14mm diameter output shaft with B-10 Euro-Flange mounting is available.
Inductive measurement technology with signal processing, provides absolute rotary position values with up to 19 bits single-turn and 16 bits turn-counting are available for a 35 bit measurement capability. The multi-turn function on the 900 series is implemented without mechanical gearing. The turn counting function is implemented via solid-state electronics with internal back-up power. There are no gears or moving parts and no external power is needed to retain the absolute position values. Communications with control electronics can be provided via DRIVE-CLiQ, EnDat, SSI, PROFIBUS and Incremental quardature formats in both single and dual encoder implementations.
For example, 35bit position with EnDat plus 1Vpp outputs can be provided in parallel with a High Current High Voltage TTL output with virtually any resolution up to 3278ppr.
