SBT5VHFL

Overview

The SBT5VHFL is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for medical applications. It features an internal driver circuit and operates on DC input with a frequency of 2.075kHz. The device produces a sound pressure level of 90dB and draws current consistent with its medical-grade specifications. It utilizes a flange mounting style with a diameter of 44.45mm. The unit emits a repeating tone every 2.5 seconds, ensuring distinct audible alerts in clinical environments.

Feature Summary

• Medical-grade piezoelectric technology for reliable acoustic signaling
• Internal driver circuit simplifies integration into alarm systems
• Flange mounting design ensures secure panel installation
• Repeating pulse pattern provides clear auditory indication

Applications
