ʻO ka moʻo Pi20 he ʻāpana ʻāpana kila kila me ka 20 µm pitch incremental graduations i kahakaha ʻia ma ka cylinder a me kahi hōʻailona kuhikuhi optical.Loaʻa ia i ʻekolu nui, 75mm, 100mm a me 300mm ke anawaena.Loaʻa i ka rotary encoders ka pololei kau kau ʻana a loaʻa i kahi ʻōnaehana hoʻopili tapered e hōʻemi i ka pono o nā ʻāpana mīkini hoʻomanawanui kiʻekiʻe a hoʻopau i ka misalignment waena.Loaʻa iā ia nā hiʻohiʻona o ke anawaena nui i loko a me ka hoʻonohonoho maʻalahi.Hoʻohana ia i kahi ʻano heluhelu heluhelu ʻole, hoʻopau i ka backlash, torsional errors a me nā hewa hysteresis mechanical ʻē aʻe i loaʻa i nā gratings paʻa kuʻuna.
