| 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 24Vdc supply voltage, this tiny unit can supply sound levels of over 95dB at a 30cm distance. The unit will operate well with 5V TTL voltages, drawing only around 2mA. It will therefore make an excellent 'bell' or warning alarm for digital systems. Two 1· 5mm 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. |
