Schneeberger's AMSA 3-A and AMSA 4-A linear guide/magnetic encoder systems provide machines with positioning feedback in all three axes and encoder resolutions up to 0.06 µ. Units feature hard cover bands to protect the magnetic scales, and ceramic sliding elements on the electronic scanning head for protection against contamination. The company reports combining the linear magnetic scales with roller motion guides provides a cost-savings alternative to linear glass scales because the system withstands applications subject to vibration, shock, oil, dirt, and coolants. Both models feature sensor cables that attach from the back of the scan-head to the front of the electronic housing unit, reducing space requirements. The AMSA 3-A is available in roller guide sizes MR25, 35, 45, 55, and 65 and the AMSA 4-A is available in ball guide sizes BM15, 20 , 25 , 30 , 35 , 40 , and 45 .
