Ø79mm absolute encoder
This is a high-resolution, singleturn absolute encoder kit with a 22 Bit BiSS-C interface. The encoder consists of several optical reflectance sensors arranged at an angle of 180 degrees to each other. This allows to eliminate mechanical errors in the application, such as the runout of the measured shaft, by using subsequent electronics.

| Maximum humidity (non-condensing) | 98% |
| Resolution | 22 bit |
| Output code | Binary |
| Data interface | Serial BiSS C |
| Periods number of signals 1Vpp | 512 |
| Accuracy* | ≤ ± 100 arc.sec. |
| Supply voltage | 5 V ± 5 % |
| Supply current | 80 – 220 mA |
| Cutoff frequency | < 240 kHz |
| Start up time | 13 ms |
| Scan ratio of T | 40 – 60% |
| Time lag | 80 ns |
| Monoflop time | timeout + T/2 us |
| Rise and fall time | 4 – 15 ns |
| Analog signals | ~ 1Vpp (512 PPR) |
| Amplitude output voltage | 0.6 – 1.2 VDC |

*Expected at optimum installation, additional deviations due to mounting and
inaccuracy of the measured shaft are not taken into account.
Note: Maximum working rotation speed (with proper encoder counting) is
limited by maximum operating frequency and maximum mechanical rotation
speed.

| This is just an example of a specific tailor-made encoder kit, but there can be numerous variations with different interfaces, mechanical, electrical adjustments, etc. The client would have to cover the non-recurring engineering (NRE) cost for designing and manufacturing the encoder kit depending on the complexity of adjustments needed for the application. | ||
