MA-12 Motorized Actuator

About the MA-12

ASI’s MA-12 motorized actuators offer high resolution in a lightweight, compact package, and have been designed to replace manual micrometers that have 1/4″-80 threads. The MA-12-B is for use with 3/8″ barrel clamps. The units come complete with built in limit switches to provide overdrive protection and home positioning. Current limiting within the ASI control electronics also provides additional overdrive protection. The built in encoder provides 512 counts per revolution, giving a theoretical minimum resolution of 30 nm, and when used with the ASI controller provides bidirectional repeatability of better than +/- 0.75 μm.

Applications include the automation of TIRF injectors as shown in the images below, as well as automation of manual translation stages that utilize manual micrometers.
