Linear position encoders
BML linear position encoders provide direct measurement of a load's linear position regardless of actuator backlash or mechanical wear. They feature 24 m of noncontact, wear free position tracking at speeds to 10 m/s with no signal degradation over time. Two noncontact models — S1A and S1B — offer maximum resolution of 1 and 5 µm, respectively, and maximum system accuracy of ± 50 µm. They tolerate a wide operating gap — up to 0.34 and 2.0 mm for the S1A and S1B, respectively — without sacrificing accuracy.
