I have a product that uses a flat 12 mm diameter pager motor for silent signaling. I bought them surplus by the hundred, and as happens, they have run out. It ran at 3 volts, drawing 30 mA. Does anyone have a line on a similar part? I've seen some on line, but they draw 100 mils. Since the device is battery operated, I am trying to keep the draw as low as possible.
I am surprised that there isn't some piezo counterpart that can do the same thing more efficiently without noise.
