The HD-PAB2701 from PUI Audio is a 27mm diameter piezoelectric haptic actuator designed for large displacement performance in demanding applications such as micropumps, precision dosing systems, medical devices, and laboratory automation equipment. With a nominal displacement of 65μm (±15 at 155 Vp-p), it provides strong and reliable tactile response ideal for high-accuracy motion control.

Constructed with PZT-5H lead zirconium titanate ceramic bonded to a yellow brass alloy substrate, this actuator combines high performance with structural durability. Operating within a frequency range of 5 kHz ±0.5 kHz, the HD-PAB2701 delivers consistent performance at relatively low resonant impedance (≤200 Ω), ensuring efficient energy transfer in high-frequency drive environments.

Engineered for reliability, the HD-PAB2701 supports input voltages up to 155 Vp-p, functions within -24°C to +60°C operating temperatures, and maintains performance in humidity conditions up to 70% RH. Environmentally compliant under RoHS/REACH exemption 7c-1, the actuator also supports lead-free silver tin soldering at ≤280°C for streamlined integration in modern manufacturing environments.
