The HD-PAB2701-2 from PUI Audio is a thin-profile, 27mm piezoelectric haptic actuator designed for high-voltage haptics and precision displacement applications. Measuring only 0.23mm in thickness, this actuator delivers a nominal displacement of 75μm at 100Vp-p, making it an excellent choice for space-constrained designs requiring strong tactile output.

Engineered with PZT ceramic bonded to a brass substrate, the HD-PAB2701-2 provides a balance of durability, sensitivity, and efficient energy transfer. Its resonant frequency of 2 kHz (±500 Hz) makes it ideal for applications that demand lower-frequency operation with higher displacement response compared to the HD-PAB2701.

With a capacitance of 45 nF (at 1V, 100Hz) and voltage range up to 100Vp-p, the HD-PAB2701-2 supports integration into medical devices, fluid pumps, haptic feedback systems, and other precision motion control solutions. The actuator is RoHS/REACH compliant (Exempt 7c-1) and supports lead-free soldering at ≤280°C, ensuring compatibility with modern assembly practices.
