Description
The Allegro Piezo Alarm 987101D is a small, compact piezoelectric buzzer or alarm designed for a wide range of applications, including consumer electronics, security systems, and other devices that require sound output. Here’s a more detailed breakdown of its characteristics:
Key Features:
-
Piezoelectric Technology: It uses piezoelectric elements to generate sound, which makes it highly efficient with low power consumption. Piezo buzzers are known for producing loud sound from a small, energy-efficient form factor.
-
Voltage Range: Typically operates with a voltage input around 5V, though this can vary based on the specific model and application. Some versions may tolerate wider voltage ranges.
-
Tone and Sound Output: Produces a high-pitched sound or alarm, often used for signaling or alert purposes. The tone can be continuous or pulsed depending on the design.
-
Compact and Durable Design: Small in size, which makes it suitable for compact devices, yet still capable of producing a loud output. It’s also generally durable and can operate in a variety of environmental conditions.
-
Low Power Consumption: Piezo buzzers like the Allegro 987101D are designed to consume minimal power, which is ideal for battery-operated systems.
-
Connection: Typically connects via simple electrical leads or pins, which can be soldered directly to a circuit or device. This makes installation easy in electronic projects.
