# Transducer, Buzzer, 20 V, 70 dB ![Product image](https://novapart.co/image/farnell:3407763/) **URL**: https://novapart.co/products/PS1550L40N/transducer-buzzer-20-v-70-db **SKU**: PS1550L40N **Manufacturer**: TDK **Category**: Sensors & Transducers || Transducers || Sensing Transducers || Piezo Transducers **Price**: €0.4510 **Stock**: 1000+ **Lead Time**: 2 days (indicative) ## Specifications | Parameter | Value | |---|---| | Product Range | PS | | Sound Level Spl | 70dB | | Resonant Frequency | 5kHz | | Supply Voltage Max | 20V | | Transducer Function | Buzzer | | Sound Level Distance | 100mm | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3407763/) July 2019 oi **RoHS SVHC-FreeREACH** ## Piezoelectronic buzzers Without oscillator circuit Pin terminal/Lead lines/SMD ## PS series **Pin terminal type PS12 PS14 PS17 PS19** **Lead wire type** **PS15** **SMD type PST14** (2/17) ## **Piezoelectronic buzzers** ## **Product compatible with RoHS directive** **Without oscillator circuit Pin terminal/Lead lines/SMD** ## **Overview of the PS series** ## **FEATURES** - Sounding body(unimorph) that piezo bonded the diaphragm is used, and attach on circuit, and is easy design high performance efficiency piezoelectric buzzer. - They feature extremely low power consumption in comparison to electromagnetic units. - Because these buzzers are designed for external excitation, the same part can serve as both a musical tone oscillator and a buzzer. - They can be used with automated inserters. Moisture-resistant models are also available. - The lead wire type(PS1550L40N) with both-sided adhesive tape installed easily is prepared. ## **APPLICATION** Electric ranges, washing machines, computer terminals, various devices that require speech synthesis output. ## **RECOMMENDED OPERATING CIRCUIT EXAMPLE** **==> picture [210 x 113] intentionally omitted <==** **----- Start of picture text -----**

Please note that the contents may change without any prior notice due to reasons such as upgrading. 20190717 / piezoelectronic_buzzer_ps_en.fm (17/17) ## **REMINDERS FOR USING THESE PRODUCTS** Before using these products, be sure to request the delivery specifications. ## **SAFETY REMINDERS** Please pay sufficient attention to the warnings for safe designing when using this products. ## **REMINDERS** Please be sure to read the specifications of TDK electromagnetic buzzer(hereinafter referred to as “the buzzer”) before use. - O Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect the performance. - O Do not supply any voltage higher than applicable to the piezoelectric buzzer. - O Do not use the piezoelectric buzzer outdoors. It is designed for indoor use. If the piezoelectric buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture. - O Do not wash the piezoelectric buzzer with solvent or allow gas to enter it while washing; any solvent that enters it may stay inside a long time and damage it. - O A piezoelectric ceramic material of approximately 100  m thick is used in the sound generator of the buzzer. Do not press the sound generator through the sound release hole otherwise the ceramic material may break. Do not stack the piezoelectric buzzers without packing. - O Do not apply any mechanical force to the piezoelectric buzzer; otherwise the case may deform and result in improper operation. - O Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like. - O Be sure to solder the buzzer terminal at 350°C max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver. - O Avoid using the piezoelectric buzzer for a long time where any corrosive gas H2S, etc.) exists; otherwise the parts or sound generator may corroded and result in improper operation. - O Be careful not to drop the piezoelectric buzzer. - O High safety and reliability is needed, and or, there is fear that failure, wrong movement, failure of product damages and worldly goods etc related to life and health of people, or do not use for equipment(as nuclear power equipment-?automobile?-aircraft-?medical? device) with fear that significant influence is had socially. - O The products listed on this catalog are intended for use in general electronic equipment (AV equipment, telecommunications equipment, home appliances, amusement equipment, computer equipment, personal equipment, office equipment, measurement equipment, industrial robots) under a normal operation and use condition. The products are not designed or warranted to meet the requirements of the applications listed below, whose performance and/or quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage to society, person or property.
