Multi-Application buzzer
Pagina 1 van 3
The Sonitron Multi-Application buzzers are low cost commercial grade
components for large volume applications. The SMA series are
designed to meet a wide range of current consumption, voltage, sound
pressure, mounting methods, connection, dimensions and packing
requirements. The buzzers have a built-in oscillator generating their
working frequency. They produce a highly reliable audible tone signal,
giving either an extremely clear and penetrating tone or a soft sound for
non-aggressive signals.
ADVANTAGES & APPLICATIONS
ADVANTAGES :
• octagonal form
• models with different pin pitches
• light but solid state construction
• little power consumption, especially the extra
loud LC-versions
• important voltage range (1,5V to 24V)
• easy mountable
• small size for applications with limited space
• SMD models with heat resistant label for
protection during automatic soldering, packed
in trays for automatic placing
APPLICATIONS :
• portable battery operating devices
• audible alarms
• gas detectors
• weighing and measuring equipment
• medical instrumentation
• timers
• control instrumentation and systems
• copiers
• automobiles
• games and toys
• computer peripherals
• cash registers
• etc.
