Piezoelectric Transducers NBL Langevin Bolt-on Transducers Overview Applications KEMET's Langevin-type transducers are used whereever powerful ultrasonic waves must be generated. For application flexibility and ease of installation, these transducers are mounted in a structure that can be bolted virtually anywhere. * Cleaning equipment * Ultrasonic treatment machines * Welders for plastic KEMET's high-performance ceramic material NEPEC(R) N-61 is excellent for use in these Langevin transducers. KEMET produces a number of this type of transducers, all featuring high quality and excellent output levels, and all based on a unique proprietary design. Benefits * High mechanical Q and excellent electro-acoustic conversion efficiency, providing a high output amplitude * High speed of vibration due to piezoelectric element * Fast and easy installation * High reliability * Operating temperature range from -40C to +120C * Good amplitude linearity due to N-61 ceramics' extended temperature range * RoHS/REACH compliant Ordering Information NBL 45 28 2 H A 3 Series Diameter of Acoustic Wave Radiation Resonant Frequency Number of Piezoelectric Elements Construction Type Radiation Surface Model Type H = Horn construction (output surface has step or horn shape) S = Straight construction Blank = Not available for treatment machines type A = Threaded type for cleaning equipment Blank 3 NBL 15 = 15 mm 20 = 20 mm 45 = 45 mm 28 = 28 kHz 40 = 40.2 kHz 60 = 60 kHz 2 = 2 elements One world.

Report for content of REACH SVHC list: The product(s) above contain a substance by more than 0.1wt% per product weight that was published in the 8th update of the REACH SVHC substances (December 19, 2012). 3. Regarding safety of the piezoelectric transducers (Piezoceramic products): The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as a main ingredient. It is chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics. 4. Technical product information on the piezoelectric transducers (Piezoceramic products): The manufacturing technique of the "piezoceramic products" whose main ingredient is Lead Titanium Zirconium Oxide (PZT) has been established, and there is no alternative material that can exhibit superior performance than PZT at this moment. Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) Annex III (7c.1). 5. Responsibility of piezoceramic manufacturers: Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the article 33 of the REACH regulation.

For proper evaluation and decision, products should be tested repeatedly in both realistic and abnormal operating conditions. * * * * * Do not disassemble the product or remove the screw. Avoid excessive physical shock. Otherwise, the internal piezoelectric ceramic element may be damaged. Do not apply power exceeding its maximum allowance. Store the transducers preferably at ordinary temperatures (-20C to +80C). Avoid condensation on the product's surface. Handle products properly as industrial waste. When disposing, please contact your local waste disposal service and make sure the disposal methods meet all legal requirements. * Transducers' stock should be used promptly, preferably within 1 year of receipt. Export Control For customers in Japan For products which are controlled items subject to the "Foreign Exchange and Foreign Trade Law" of Japan, the export license specified by the law is required for export. For customers outside Japan Piezoelectric Transducers should not be used or sold for use in the development, production, stockpiling or utilization of any conventional weapons or mass-destructive weapons (nuclear weapons, chemical or biological weapons, or missiles), or any other weapons.
