The HD-PAC2102 is a disc-shaped piezoelectric actuator engineered for strong haptic feedback and fast response in thin-profile designs. Measuring just 21mm in diameter and 1.52mm thick, it balances compact form factor with powerful tactile performance.

With a resonant frequency of 14 kHz (±1 kHz) and a nominal displacement of 50μm, the HD-PAC2102 delivers robust haptic sensations for applications such as touchscreens, medical equipment, VR/AR interfaces, and portable electronics. Its titanium cymbal construction enhances durability and displacement force, while its high capacitance of 400nF (@1V, 1kHz) supports efficient signal responsiveness.

This actuator is RoHS/REACH compliant (Exempt 7c-1) and optimized for hand solder and low-melting solder assembly, ensuring compatibility with modern production methods.
