Doesn't live up to safety standards

According to my experience, these industrial and scientific components are not reliable for ensuring proper facility safety. While the product may be affordable, it fails to meet the necessary safety standards and can put workers at risk. The only pro is its low price point. However, the cons are multiple - including inadequate quality control and poor performance. I would not recommend this product to anyone looking for dependable occupational health and safety products.

Pros
  • Highly efficient and reliable performance
Cons
  • Prone to malfunction in harsh environmental conditions

5V = bad, 3.3V = hardly works

They appear to be designed for 12V applications. I couldn't get any sound from them by applying 3.3V without applying PWM to them. 5v same story. What I got from them was very low volume. I also bought a few other piezos - also active ones - and they are significantly louder and can be driven directly with 3.3V, just by applying 3.3V to the wires you get a nice loud beep. 5v, same story. However, they are quite confident that they have fairly optimistically called this suitable for…

Pros
  • Rated voltage: 5V Working voltage: 4-8V Rated current (MAX): 30mA Minimum sound level at 10cm: 85dB Resonance frequency: 2300 +/- 300Hz.
Cons
  • No power
