Piezo Indicator Generates Loud Sound

Sporting a form-factor consistent with common piezo indicators, but generating roughly double the sound pressure, is how the company characterizes the KPI-800 family. The new 26-mm diameter by 22-mm high piezo audio indicators have a lead pitch of 15 mm and develop a sound pressure of 100 dBA (minimum). The devices are epoxy sealed at the base and are available with a remove-after-washing tab in both PC-mount and wire-leaded versions. Standard operating voltage is 6-18 Vdc. Price is sub-$1.00 each in moderate quantities. For more details, contact Steve Schweter at EHM TECHNOLOGY INC., Bolingbrook, IL. (630) 771-0579.
