Other Companies EOL Piezo Buzzer Cross Reference Table (July Updated Version)

For those having trouble with Murata Manufacturing's piezo buzzer, sounder, and piezo elements EOL.

At Same Sky, we continuously manufacture and sell magnetic buzzers and piezo buzzers. Among these, we have received numerous inquiries regarding the EOL (end-of-life) piezo buzzers produced by Murata Manufacturing, so we have listed our products that are believed to be as close as possible.

• Sound Parts

The Same Sky three-wire piezo element utilizes a feedback terminal, allowing it to sound at a single frequency with a simple circuit.

The Same Sky piezo element comes in 2-wire and 3-wire models, with the 3-wire type utilizing a feedback terminal, allowing it to operate at a single frequency with a simple circuit. We have added a feedback-type piezo element that can achieve efficient high sound pressure at the resonant frequency, with a minimum size of Φ12mm x 0.13mm and a resonant frequency range of 2kHz to 4.9kHz.

• Sound Parts

Piezoelectric element (diaphragm) capable of achieving sound generation functionality with a minimum volume, with diameters ranging from φ15 mm to φ44 mm.

A new product with a diameter of φ12mm, the smallest to date, has been added to our lineup of piezo elements that are easy to incorporate into various products with a thickness of less than 1mm. In addition to this, we also offer sizes φ15mm, φ20mm, φ27mm, and φ35mm, each available with or without lead wires, allowing you to add sound functionality to your application in minimal space.

A new type of standard pin-mounted buzzer (sounder, transducer = external drive circuit type) with a pin pitch of 5mm has been introduced.

A standard and easy-to-handle pin-type buzzer (transducer with an external drive circuit) with a 5mm pitch, which has been highly requested, is now available. It is a magnetic type, and we offer commonly used sizes of Φ12 x 9mm and Φ16 x 12mm.

A new series of buzzers with LED has been launched. These are panel-mounted buzzers with pins available in red, blue, yellow, and green.

The lineup of CUI's buzzers has introduced the 4 series with LED options. Each series offers red, blue, yellow, and green color options, and for the Φ13.8 size, a 1.2Hz pulse (intermittent sound) output type is also available. Furthermore, the Φ32.8 series is IP68 rated for dust and water resistance.

The smallest buzzer and piezo sounder from CUI are newly introduced. They are ultra-compact SMT types that enable alarm functions in a compact form.

CUI Devices offers a lineup of buzzers, including the "Indicator" with a built-in drive circuit and the "Transducer" (Sounder) with an external drive circuit. We have released the smallest and thinnest Indicator to date, the "CMI-8536-82-SMT-TR," and the smallest piezo-type Transducer, the "CPT-7502-65-SMT-TR." Both models are surface mount types, making them easy to incorporate into portable and wearable applications due to their ability to sound in minimal space.

1.9mm thinnest piezo sounder new products CPT-9019A-SMT-TR, CPT-9019B-SMT-TR

A new model with a sound pressure of 72dB has been added to CUI's piezo buzzer (transducer with external drive circuit) in the smallest size of 9mm x 9mm. It is only 1.9mm thick, making it ideal for portable and wearable applications. It achieves a sound pressure of 72dB, which is more than double the previous 65dB for the same size, and the operating temperature has also been improved to -40℃ to +85℃, allowing for compatibility with a wider range of applications.

Recent introduction of magnetic buzzer products that have been frequently inquired about. Ideal for consideration of replacement from other companies due to widely used sizes and pin pitches.

We will introduce some of the magnetic buzzer products that have been frequently inquired about recently. We offer buzzer indicators that have a built-in drive circuit and sound when a DC voltage is applied, as well as transducers (sounders) that require an external drive circuit and can be used at your preferred frequency. These products come in widely used sizes and pin pitches, and their drive voltages make them suitable for consideration as replacements from other companies. At CUI, we continue to develop our product offerings while maintaining a sustainable supply of products through the establishment of a production system with a moderate MOQ, and we will strive to continue supporting our customers' development and production. Built-in circuit, pin type: CMI-1295-0585T 5V 85dB 2,300Hz φ12 x 9.5 CMI-1295-1285T 12V 85dB 2,300Hz φ12 x 9.5 CMI-1614-0685T 6V 85dB 2,200Hz φ16 x 14 CMI-1614-1285T 12V 85dB 2,200Hz φ16 x 14

The time for celebration has come! The new production hall has started operations! While finishing work continues in other parts of the building, metal shavings are already being produced in the first machining center. Last Friday afternoon, employees and their families, along with companies involved in the construction, gathered to celebrate the achievements so far. Cold drinks, hot barbecue, and an ice cream stand were provided. During the celebration, many employees had the opportunity to tour the entire new building for the first time. Visitors were introduced to the new machines and improved logistics through guided tours of the production area. The new training room, the training center on the upper floor, and the latest conference room for customers were also unveiled. With this new building, Volkmann GmbH has secured an additional 4,500 square meters of production space. This expansion was very important, as the existing hall had already reached its limits due to the company's ongoing growth and increased production volume.

▶Issue: Before further processing the powder in the next stage (such as packaging machines), it is necessary to inspect for the presence of metal foreign objects using a metal detector. To achieve high sensitivity, the powder needs to be inspected through free fall, but due to low ceiling height and operational inconvenience, it is not possible to install the metal detector in the next stage. ▶Solution: The CEIA metal detector will be installed under a Volkmann vacuum conveyor and on a Volkmann mobile lift. The height-adjustable lift will allow the product discharge outlet of the metal detector to be adjusted to the appropriate height for the mobile container. Additionally, the vacuum conveyor can be lowered to a height that allows the mobile lift to pass through doors. The powder will be transported, for example, from an IBC container to the mobile lift and then to the metal detector via vacuum transfer. Metal foreign objects will be sorted and collected in a separate bottle. The inspected powder will be collected in a mobile container. Another vacuum conveyor is installed for the next stage, such as the packaging machine, from which the powder will be drawn from this container. Inspection and separation of metal parts can be conducted very close to the next stage, and it is also possible in more distant production areas.

The video shows that there is a tank at the bottom of the vacuum conveyor, and steam is constantly being released (in a simulated manner). If no measures are taken, the steam will enter the inside of the vacuum conveyor, condense into water droplets, and cause powder adhesion. Both our company and our customers have been troubled by such installations. This time, with the special module jointly developed with Minato Engineering Co., Ltd., we have succeeded in blocking the rising steam. From around the middle of the video, you can see that this function is turned on. You should be able to understand that the steam that was previously rising has disappeared. As a result, it has become possible to install equipment in a steam atmosphere, which was previously difficult to do, with peace of mind.
