About this product

Overview

  • 3V to 24VDC operation

Product overview

An extremely loud PCB-mounting, piezoelectric buzzer designed to operate over a wide range of supply voltages. It has a built-in driver circuit and requires only a DC voltage to drive it. Working with a 24 Vdc supply voltage, this tiny unit can supply sound levels of over 95 dB at a 30 cm distance. The unit will operate well with 5V TTL voltages, drawing only around 2 mA. It will therefore make an excellent ‘bell’ or warning alarm for digital systems. Two 1.5 mm dia. holes are required 16mm apart. The case is finished in a cream colour, and features a dot to indicate the side with the positive terminal.
