SC110EJ

Overview

The SC110EJ is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on AC or DC voltages ranging from 30V to 120V with a current draw of 6 to 20mA. The device emits a slow pulse tone at a frequency of 2kHz and achieves a sound pressure level of 60dB at 30V measured at 61cm. It features panel mount installation via screw terminals and quick-connect tabs (0.250 inches). Certified by UL and cUL, it functions within a temperature range of -30°C to 65°C.

Feature Summary

• Internal driver circuitry enables direct connection to AC or DC power sources without external drivers.
• Slow pulse operating mode provides distinct auditory alerts suitable for industrial environments.
• Dual termination options include screw terminals and quick-connect tabs for flexible wiring integration.

Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Equipment fault signaling

Procurement Notes

Verify the specific voltage rating and acoustic output requirements against the official datasheet before ordering. Confirm that the mounting hole dimensions match the panel design. Ensure the application environment stays within the specified -30°C to 65°C operating temperature range. Check for required certifications such as UL or cUL compliance for your region. Validate terminal type compatibility with existing wiring infrastructure.

Selection Notes

Select this model if a moderate volume alert is sufficient for the installation location. The 2kHz frequency offers a balance between audibility and harshness. Consider the SC110DJR variant if a different pulse rate is preferred. Evaluate the SCH series if higher sound pressure levels or hazardous area certifications are necessary. Ensure the 42.85mm diameter fits the available panel space.
