Product overview

  • Wire ended high-powered piezo electric buzzer
  • Integral drive circuit
  • Very wide operating voltage range

An extremely loud piezo electric buzzer with integral drive circuit and a very wide operating voltage range.

Rated 4 out of 5 by from Medium frequency sounder I wish suppliers would call these thing sounders not buzzers. It does not buzz but emits a tone which is neither particularly low or high. I bought this to match another I had in stock left over from a previous project and it does the job well. When two are fitted close to each other the very low beat frequency improves the effectiveness of the alert sound that I needed to create. A good product but definitely does not 'buzz'.

Sorry to bother you again, but most important to me is the orifice diameter (the orange area on the picture) and the SPL behaviour for different frequencies. Do you have any of these information? Thanks a lot in advance!

Asked by: Harvester
I have sent the data sheet for the item to the email address provided.

Hi, can you also tell me the diameter of the orifice size? Or is there any possibility to get a data sheet of the piezo buzzer?

Asked by: Harvester
I will forward you a copy of the datasheet I have on file. The diameter is 39mm and 50mm between the centre of each securing hole.
