SBS12ELMMPPC

Overview

The SBS12ELMMPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 12 VDC and features a built-in oscillator for continuous tone generation. The device utilizes a metal case construction with a top-mounted sound port, designed for robust industrial applications. Key electrical characteristics include a typical current draw of 30 mA and an operating frequency range centered around 2.7 kHz. The unit is engineered to provide reliable acoustic signaling in environments requiring durable, low-power notification components.

Feature Summary

• Integrated oscillator circuitry enables direct DC drive without external timing components
• Metal housing provides enhanced durability and electromagnetic shielding compared to plastic variants
• Top-port design facilitates directed sound output for clear audible alerts

Applications

• Industrial machinery status indicators
• HVAC system fault alarms
• Medical equipment operational feedback

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to ensure compatibility with required mounting configurations and terminal types. Confirm that the 12VDC rating aligns with your system's power supply specifications. Check for any environmental certifications if deployment involves extreme temperatures or humidity. Ensure the metal case grounding requirements are addressed in your PCB layout design to prevent interference.

Selection Notes

Select this component when a self-oscillating buzzer with higher mechanical robustness is required. The metal case variant offers superior protection against physical impact and EMI compared to plastic-cased alternatives. Consider the 30 mA current consumption during battery life calculations. Ensure the 2.7 kHz frequency matches the desired audibility profile for your specific application environment.

Part Context

This model belongs to Mallory's SBS series of piezoelectric buzzers, known for their reliability in commercial and industrial settings. The SBS line typically includes various voltage ratings and case materials. This specific part represents the 12VDC metal case option within that family, distinguishing it from lower voltage or plastic-housed counterparts.

Replacement Considerations

Direct replacements must match the 12VDC operating voltage, similar form factor, and metal case construction. Verify pinout compatibility before substitution. Alternative models from other manufacturers may require adapter boards due to differing terminal configurations.
