SC105

Overview

The SC105 is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on a low voltage DC input range of 1 to 5 volts with a current consumption between 3 and 16 mA. The device generates a continuous tone at a frequency of 1900 Hz. Its acoustic output provides medium loudness, specified as 60 to 75 dB. The unit features a compact circular form factor suitable for industrial audio indication applications requiring simple internal drive circuitry.

Feature Summary

• Internal driver circuitry enables direct connection to power sources without external oscillators
• Piezoelectric technology ensures reliable operation across specified temperature ranges
• Panel mount design facilitates secure installation in control panels and enclosures

Applications

• Industrial machine status indicators
• Control panel alarm systems
• Low-voltage electronic equipment alerts

Procurement Notes

Verify the specific voltage rating and tolerance requirements against your system's power supply before procurement. Confirm that the 1-5VDC operating range aligns with your design constraints. Ensure the physical dimensions match your panel cutout specifications. Check for any updated RoHS compliance documentation if required by your regional regulations. Validate the acoustic output level meets your environmental noise requirements.

Selection Notes

Select this component when a low-voltage, internally driven audible indicator is required. The SC105 is appropriate for designs where space is limited and external driving components must be minimized. Consider the 1900 Hz frequency for optimal human audibility. Compare against other SC series models if higher voltage or different sound patterns are needed. Ensure the panel mounting style fits your enclosure design.
