Designed for multi-speaker setups, it effectively repels a wide range of pests including rodents, insects, and birds. Its durable, fully potted enclosure ensures reliable automatic operation, making it an essential tool for protecting homes, gardens, and vehicles. ## Description Through ultrasonThrough ultrasonic sounds it is possible to scare away animals and insects like rats, mice, martens, wild rabbits, mosquitoes. If mounted on the car, roe will be put to rout (decreased danger of accidents). Connection of a piezo-treble loudspeaker to the module is an ideal way to scare away destructive animals out of your pantry, kitchen, storehouses, garden, etc. Also can be used as dog whistle. Even some birds species will be scared out of your fruit trees.Item SpecificsOperating voltage: 12 - 15 V/DCCurrent consumption: <50 mALoudspeaker output: up to 5 piezo loudspeakersAudio frequency: adjustable ~8 - 40 kHz (± 20%)Size: 60 x 45 x 29 mm (without fastening straps)A speaker & power supply are required for unit to function properly. Indicator light will not turn on without a speaker and power supply wired to the unit. ## Features - Compact circuit is housed in a fully potted plastic enclosure and can be powered from any 12~15VDC power supply - When connected to a piezoelectric speaker, the device emits ultrasonic tones from 8KHz~40KHz, ideal for repelling insects, birds, rodents and other pests - Up to four piezo speakers may be connected to a single module. Top mounted 10 position rotary switch selects output frequency - Note: May or may not have a frequency adjustment knob. Some units will have a flat adjustment with a slot to insert a screwdriver to adjust the frequency. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NRH95AY | | Actuator Type | Rotary | | Best Sellers Rank | #351,495 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #167 in Function Generators | | Brand Name | KEMO | | Circuit Type | multi-way | | Color | Black | | Compatible Devices | Piezo-Treble Loudspeakers, Devices requiring Rotary Actuator | | Compatible with Vehicle Type | Car | | Connectivity Protocol | X-10 | | Connector Type | Plug In | | Contact Material | Metal | | Contact Type | Normally Open | | Control Method | Touch | | Control Type | Manual | | Controller Type | Push Button | | Current Rating | 50 milliamps | | Customer Reviews | 4.2 4.2 out of 5 stars (239) | | International Protection Rating | IP00 | | Item Weight | 16 ounces | | Manufacturer | Kemo Electronic | | Material Type | Plastic | | Model | 4330881478 | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Positions | 1 | | Operating Voltage | 15 volts | | Operation Mode | automatic | | Part Number | M048N | | Specification Met | Ma | | Switch Type | Rotary | | Terminal | Physical | | Unit Count | 1 Count | | Upper Temperature Rating | 60 °C | | Wattage | 4 watts | ## Product Details - **Brand:** KEMO - **Circuit Type:** multi-way - **Connector Type:** Plug In - **Contact Type:** Normally Open - **Current Rating:** 50 milliamps - **Material:** Plastic - **Operating Voltage:** 15 volts - **Operation Mode:** automatic - **Switch Type:** Rotary - **Terminal:** Physical ## Images ![KEMO Ultrasonic Signal Generator Module, Push Button Switch, Rotary Actuator, Automatic Operation, Black - Image 1](https://m.media-amazon.com/images/I/6123XN9NvhL.jpg) ![KEMO Ultrasonic Signal Generator Module, Push Button Switch, Rotary Actuator, Automatic Operation, Black - Image 2](https://m.media-amazon.com/images/I/81Qy61nGqkL.jpg) ![KEMO Ultrasonic Signal Generator Module, Push Button Switch, Rotary Actuator, Automatic Operation, Black - Image 3](https://m.media-amazon.com/images/I/61MaBQOGHcL.jpg) ## Questions & Answers **Q: Someone mentioned the frequency fluctuates. Can you lock in a frequency or does it always fluctuate?** A: My unit does "waver" at about 2 Hz around the set center frequency. When in the audible region it sounds like a sound effect in an old TV show. The "wavering" is definitely an intentional design feature, not a problem with the circuitry. I watched the output on an oscilloscope and the wavering continues even as the frequency moves to the highest end of the frequency range. For any use other than a pure signal generator, like trying to drive away critters, the wavering is probably a good design feature. **Q: If I use this device + piezo loudspeaker + bullhorn will I be able to get the desired effect on a dog about 150-200 ft away?** A: It works good on some dogs at that range, but others can be within 50 and ignore it. We had 3 dogs next to us and 2 of them never noticed and the 3rd one would stop barking and run for the house. He would head to the house when he was at least 200 feet away, he soon became a non barking dog. **Q: Any idea what AC power adapter to power this unit? thanks** A: i used 12v 1A unit.. **Q: Can this run on batteries? Or only DC power plug?** A: Batteries such as AA or AAA or similar chemical batteries are DC. The device does not come with a battery compartment. I guess if you attached a battery the device would work. ## Frequently Bought Together - KEMO Ultrasonic Signal Generator Module, Push Button Switch, Rotary Actuator, Automatic Operation, Black - Piezo Loudspeaker for Ultrasonic Power Cannon (M161) Kemo part L010 - Piezo Spherical Dome Tweeter with Flare (L001) for ultrasonic Sound Generator M048N --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/11258613-kemo-ultrasonic-signal-generator-module-push-button-switch-rotary-actuator](https://www.desertcart.ae/products/11258613-kemo-ultrasonic-signal-generator-module-push-button-switch-rotary-actuator) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-08-10*
