This wired active piezo buzzer uses durable black ABS housing. The engineering drawing shows complete outline size, mounting hole position and red/black lead wire structure. The two mounting ears allow easy panel installation without extra bracket. Built-in circuit makes it simple to operate: just connect DC power to red and black wire to trigger alarm sound.
Our lead-wire active piezoelectric buzzers are widely used for audio warning and reminder signals:
Industrial control cabinets
Security alarm systems
Automatic production machinery
Elevator & lifting equipment
Medical diagnostic instruments
Vehicle backup warning devices
IoT monitoring alarm modules
