Kemo M100N – 12V Ultrasonic Mouse and Marten Repellent for Cars and Campers

Kemo M100N: ultrasonic repellent for the engine compartment

The Kemo M100N is an electronic device designed to deter mice and martens from the engine compartment, helping to reduce the risk of damage to wiring, pipes, and vehicle components. It is suitable for cars, campers, vans, and other vehicles with 12V systems.

The module combines pulsating ultrasound at approximately 23 kHz with a flashing LED . The piezoelectric transducer with a spherical aluminum membrane offers a beam angle of approximately 140°. Operation is free of poisons or chemicals.

Main features

• Power supply from the vehicle's 12V DC system, with an operating range of 11 to 15V DC.
• Average consumption less than 2 mA.
• Pulsating ultrasound and flashing light signal.
• Soft-start and sealed electronics.
• Suitable for vehicles equipped with CAN bus.
• Compact size for installation in the engine compartment.
