Can AksIM-4 operate in ultra-high vacuum?

AksIM-4 encoders were tested for outgassing under ultra-high vacuum conditions with test parameters similar to the ECSS-Q-ST-70- 02C (2008) and ASTM E595-15 (2021) standards. No critical outgassing was detected. The relative mass loss (RML) of the ring and readhead were 0.01 % and 0.09 %, respectively. The ultra-high vacuum test had no effect on the performance of the encoder.
