1) Suitable for applications that measure the time between individual TTL output signal edges;
non-clocked output signals provide for a lower amount of edge jitter

2) Maximum scanning frequency during referencing: 70 kHz

1) The position error within one signal period and the accuracy of the graduation together yield the encoder-specific error;
for information on additional errors as a result of mounting and bearing of the measured shaft, see Measuring accuracy
in the brochure Modular Angle Encoders with Optical Scanning
