Sealed buzzers have a "SR" suffix in the part number. For example, P/N MSR320SR is sealed and appropriate for aqueous wash. P/N MSR320R is not sealed. After aqueous wash, the wash label must be removed from the buzzer. Wave Solder Profile: Refer to the wave solder machine manufacturer's recommended wave solder profile. If needed, adjust the maximum time & temperature to 270C for 3 seconds to process MSR & MSO series buzzers. Moisture Sensitivity Level (MSL): Level 1 (Unlimited) Packaging: All parts are bulk packed. Origin: Made in USA Sound Level vs Distance: Sound level decreases as the sound waves travel over distance, so it is important to note the specified distance when comparing sound levels. For example, if a buzzer measures 88 decibels (dB) at 30 cm, then it will measure: 97 dB @ 10 cm 82 dB @ 60 cm 78 dB @ 1 Meter Mallory Sonalert has developed a tool to help convert sound levels depending on the distance.
