Overview
The SBT5GMCMPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC input and features a 44.45mm diameter with through-hole mounting capabilities. The device produces a sound frequency of 2.075kHz in a medical-rated configuration. As an active component, it includes internal drive circuitry to simplify integration into alarm systems requiring specific acoustic signaling profiles.
Feature Summary
- Internally driven piezoelectric technology for simplified circuit integration
- Medical-rated acoustic profile designed for clinical environments
- Through-hole mounting design for secure panel or board attachment
Applications
- Medical equipment audio alarms
- Clinical monitoring system indicators
- Hospital safety alert devices
Procurement Notes
Verify the exact acoustic waveform and duration specifications against the official Mallory Sonalert datasheet, as medical variants often have unique pulse patterns. Confirm that the through-hole pinout matches your PCB layout requirements. Ensure compliance with relevant medical device electromagnetic compatibility standards for your specific application region before finalizing procurement.
Selection Notes
Select this model when a dedicated medical-grade audible indicator is required. The internal driver eliminates the need for external oscillators. Verify that the 2.075kHz frequency meets regulatory hearing sensitivity requirements for your target market. Ensure the physical dimensions fit within the designated enclosure space for your medical device assembly.
Part Context
This part belongs to the SBT5 series of industrial and medical buzzers from Mallory Sonalert. The suffix GMCMPPC typically denotes specific medical acoustic characteristics and mounting style. This series is distinct from general-purpose industrial buzzers due to its specialized sound signature optimized for clinical attention-grabbing without causing excessive distress.
FAQ
What is the operating voltage range for the SBT5GMCMPPC?
The datasheet specifies it as a DC input device, but the exact voltage rating must be confirmed via the manufacturer's technical documentation.
Does this buzzer require an external oscillator circuit?
No, it is an internally driven unit, meaning it contains the necessary drive circuitry to produce sound when DC power is applied.
