Bending Piezo

The BA Series are piezoelectric bimorph actuators poled in the parallel configuration. An insulated resin coating is applied to the external surfaces to protect the actuator and to eliminate electrical faults. The actuators can be wired in a three-wire or two-wire configuration as illustrated below.

The three wire configuration requires a single +200V supply; however, a bipolar configuration with a +/-100V supply is electrically equivalent. In the two-wire (AC) configuration, the maximum deflection and force is reduced by 30%.

Wires can be attached using conductive epoxy (Circuitworks CW2400) or standard solder and Rosin flux. After flux application, a one second contact with a 300C iron is recommended. The positive terminal is indicated by a red stripe.
