10PCS 27mm Piezo Disc Sensor with Wire for Electronic Drum Trigger, Sensitivity Dual Sounder Set

10 pieces 27 mm piezo elements with copper wire for sounder, sensor, trigger, and drum disc applications Key benefits Ready supply for repairs and prototyping: Ten identical piezo discs let you failed parts or outfit multiple projects without repeated ordering. Dual function: Each disc can act as a sounder to generate tones or as a sensor to detect vibration and impact, reducing the number of different components you need. Easy to integrate: Preattached copper wire simplifies soldering and connection to circuits, controllers, amplifiers, or breadboards. Product highlights Quantity: 10 pieces for consistent, repeatable results across projects. Size: 27 millimeter diameter discs, suitable for many standard housings and mounts. Material: Piezoelectric element with copper lead wire for reliable electrical connection. Function: Designed for sound generation, vibration sensing, trigger inputs, and percussion pad use. Performance: Sensitive to mechanical input and usable both in passive sensing configurations and driven sounder circuits. Practical applications Electronic percussion pads and drum triggers: Mount the discs under pads to convert strikes into electrical trigger signals for drum modules or sound modules. Alarm and sensor systems: Use as vibration or impact sensors for door contacts, tamper detection, or simple acoustic alarms. DIY electronics and audio projects: Incorporate into buzzers, tone generators, contact microphones, or experimental sensor circuits. Installation and compatibility notes The copper leads are ready for soldering or for use with screw terminals and connectors. Cut or strip the wire to fit your wiring method. Mounting can be done with small hardware, foam or adhesive spacers to control acoustic coupling and sensitivity depending on the application. Compatible with common microcontroller inputs, amplifier circuits, and signal processing modules when paired with appropriate circuitry. What you get A set of ten 27 mm piezo discs with copper wire, suitable for sounder, sensor, trigger, and drum disc uses, supplied as identical replacements or components for multiple builds. This kit provides a straightforward way to add or piezo sensing and sounder elements in electronics, musical instruments, and sensor projects.
