![]() I don’t know if these details make any difference to the question, but the disc is somewhat oversized (2 inches metal diameter), and the disc is wired with slightly thicker gauge wire than the rod (which is wired via the standard shielded wire with the woven outer shield/ground). Applications include battery powered robotics, piezoelectric motors. Is there something about the different signal strengths of discs and rods that makes a rod come through quieter than a disc when wired in parallel through the same preamp? The PDu100 can also drive three-wire piezoelectric benders and stack actuators up to +100 V. ![]() Self-Drive type devices provide a 3rd terminal that connects to an. The disc signal is loud, but the rod signal is faint. The piezoelectric sounder element consists of a metal disc that has a special ceramic. Attach 3 black wires to the center barrel pin of each, and 3 red wires to the pin connected to. I am absolutely certain I have wired them correctly, in terms of negative and positive, with no shorts. By driving a piezo disc using an amplifier, the disc. This time I took extra care in wiring and soldering them. Thickness mode vibration application Piezo Material: SM412 Dimensions: 7mm x 0.5mm Resonant frequency fr: 4.25MHz5 Static capacitance Cs: 2.5nF 30 Test Condition: 253 C 4070 R.H. So I took the second rod piezo (the one that tested strong by itself) and soldered it and the disc in parallel, then plugged them into the preamp. Silver electrodes being two electrodes on the same side (R configuration). I thought maybe I had messed the first rod up when wiring it and the disc together. Thickness mode vibration application Piezo Material: SM412 Dimensions: 12mm x 0.6mm Resonant frequency fr: 3.4MHz5 Electromechanical coupling coefficient Kt: 47.06 Resonant impedance Zr: 0. Silver electrodes being two electrodes on the same side (R configuration). The piezo benders include three pre-soldered wire leads, and are available without a holder or pre-mounted in a rigid PEEK (polyether ether ketone) holder. ![]() I plugged a different rod piezo (by itself) into the preamp, and its signal was strong (as loud as the disc had been). Condition: New Part Number: SMD12T06R412WL Piezoelectric Ceramic disc. I tested it before installing, by tapping them on the table. I have wired a disc piezo and a rod piezo in parallel through a simple active (9V) endpin Jack preamp.
