RS PRO 87 dB, Panel Mounting Slow Pulse Internal Piezo Buzzer
Want to set up an alarm to go off with a slow pulse? This internal piezo buzzer from RS PRO will alert people to an issue without creating the sense of urgency that a faster pulse would. It will sound at 87 dB, louder than a passing truck.
The buzzer's internal drive means it doesn't require any additional circuitry to operate needed, making life easier for engineers building it into their systems. It can be used at temperatures ranging from -30°C up to +85°C, making it suitable for use in a wide range of industrial environments. The housing is flanged for easy panel mounting.
The siren conforms to US (ANSI/ESD S20.20:2014) and UK (BS EN 61340-5-1:2007) electrostatic control standards, meaning it won't damage equipment via electrostatic discharge. Sirens of this kind are commonly used in industrial process alarms.
