MODELS ON REQUEST
The SMA series can be delivered, upon special request, with the following protection :
• Wash tabs
A wash tab is glued on the sound emitting hole of the buzzer to protect it from water
penetrating into the hole of the cavity. The PCB at the back is also sealed with a silicon
film. To order this part, please add WASHTAB to the model number of the SMA series.
• Acryl coating
For applications in aggressive humid conditions, models containing a membrane with a
protective coating are available. The protective coating gives a complementary
assurance against smog. Add MC to the model number of the SMA series.
