EYE on NPI - CUI Devices' Illuminated Buzzers

Honk! Honk! This week's EYE ON NPI is jazzy, be-dazzly, and sure-to-get-your-attention-y: it's CUI Devices' Illuminated Buzzers (https://www.digikey.com/en/product-highlight/c/cui-devices/illuminated-buzzers), a set of incredibly loud audio indicators that also have built-in LEDs that light up! What a great way to quickly turn an existing design into an accessible, multi-sensory alarm system without having to redesign the enclosure or PCB.

These are very loud buzzers, good for industrial equipment - with a range of 83 to 100 dB, loud enough to alert in an office or factory. The LEDs are also nice and bright, for good indoor visibility.

There are three sizes/shapes available. The smallest is the CLI-1375 PCB-mount design (https://www.digikey.com/short/m4zc8d3z) with 13mm diameter body, which is the same shape as many PC-pin buzzers. When powered with 6 to 15V it emits a piercing 83 dB, 4 KHz square wave and the inner LEDs light up. You can get 4 different shades of translucent plastic: red, yellow, green and blue. Note you aren't expected to provide a square wave: there's an internal wave generator. There's two versions for the CLI-1375 buzzer, one has a steady tone and LED light, the other has 1 Hz-ish modulation for both the LEDs and beep.

The CLI-3224 medium size is 32mm diameter (https://www.digikey.com/short/1zwrvdf1) is a nice panel mount version with 8 SMT LEDs, four color options, and a shape that is evocative of arcade buttons. This version has spade connectors for power, and can be powered from 3 to 15 VDC. It will emit a 95 dB 3 KHz tone at the 12V rated power. Unlike the PCB-mount design, this one doesn't have a 'pulsing' version.

Finally, the CLI-3623 large size is 36mm diameter (https://www.digikey.com/short/4tnpp4fz) and is also panel mount, but with a flatter top. It also has 8 SMT LEDs, and four colors. Like the CLI-3224, 3-15VDC power is provided via spade lugs. Volume is also 95 dB at 12VDC, the tone frequency is 3.5KHz.

All 16 versions of 4 types, and 4 colors of CUI Devices' Illuminated Buzzers (https://www.digikey.com/short/b790m8vw) are in stock right now at DigiKey for immediate shipment. So if you order today, DigiKey will get the alarm to get your order out the door ASAP, and you can get beepy and blinky instantly with any configuration you desire by tomorrow afternoon.
