Users can specify ring diameters from 44mm, with an absolute resolution of up to 21 bits. The distance between the sensor and the rule is ≤0.6 mm, and the axial tolerances are around ±0.2 mm. The repeat accuracy is 0.01 degrees.
When it is switched on, the encoder provides absolute position feedback. It uses either the BiSS-C motor feedback interface or an SSI interface. As an option, it can provide an analogue output in real time with sin/cos signals of 1Vss.
The only modification needed to an installation is to attach the rule onto the shaft. With some applications, a standard Siko magnet ring can be used. The electronics can be either curved or stacked, resulting in compact assemblies.
Siko says that its in-house technologies for both rule and electronics technologies means that customs designs can be implemented quickly.
