Parameters

As a power source for this device it can be used standard sine vawe generator with tunable parameters. Regulated current up to 100 mA and resonant frequency range 280 – 350 Hz.

 

Single and Dual Axis Scanners Overview

A client asked OFH to develop a low cost, moving coil design with LED/quad sensor position sensor, closed-loop servo feedback with electronic dampening. This product is not available as an off the shelf system but serves as an example related to past work.
