rhothor Deflector RTA-AR640
OVERVIEW
This motor is capable to handle the mirror position all by itself without extra regulation or amplifier board. This makes it an easy tool to design scan solutions for generic and specific applications. These RTA (Rhothor Active) deflectors do not rely on the traditional moving magnets technology. Instead a patented moving coil principle is used. The Smart Deflector is fitted with a single coaxial connector providing power as well as data connection. Simple modulation electronics allow the user to send the set-point data directly to the motor. The mirror positioning is done by the motor itself.
