PKHPS0013E4000-A2

PKHPS0013E4000-A2 is a PKHPS0013E40 series piezoelectric sounder sensor. It uses frequency control technology to achieve a sound pressure level comparable to that of medium- or large-size sounders in spite of its compact size. This allows customers to select a compact component without having to settle for a lower sound pressure level. It compact size and high sound pressure: combines clearly audible sound pressure and compact dimensions, reducing the dimensions of the components overall as well as the mounting space needed on the board.
