Standard Series

The standard series are based on the highest piezo technology and are considered as the most robust series for industrial applications. The standard buzzers use a special shaped membrane (curved edge), which is fixed and glued into the housing. They are shockproof, as well as dust and waterproof (IP67). The different standard models cover a wide range of applications, offering functions such as continuous, intermittent, sweep, and warbler, with a sound output more than 100 dB(A).

Mounting guidelines


Printed circuit board By soldering the terminals
Front panel mountingPanel mounting with a plastic nut. The buzzers can be mounted in panels up to 14 mm thickness (SP27 max. 7mm). They are locked with a locking pin ( dimensions 0.8×2.3mm) and secured to the panel with a plastic nut: 6 Nm (Wrench size 38mm).

The step of the tread is 1.5 mm (M32 x 1.5)
