SC110HJ

Overview

The SC110HJ is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for industrial audio indication. It operates on AC or DC input within a voltage range of 30 to 120V and draws between 4 and 13mA. The device produces a slow pulse tone at a frequency of 2.9kHz with a sound pressure level of 55dB measured at 30V and 61cm. It features internal drive circuitry and utilizes screw terminals or quick-connect tabs (0.250 inch) for connection. The unit is constructed for panel mounting with a diameter of 42.85mm and functions reliably in temperatures ranging from -30°C to 65°C.

Feature Summary

• Integrated internal drive circuitry enables direct operation from AC or DC power sources without external drivers.
• Piezoelectric technology generates a slow pulse acoustic signal suitable for distinct industrial alarm applications.
• Robust construction supports flush panel mounting with secure screw terminal or quick-connect tab interfaces.

Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Electrical equipment fault signaling

Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm terminal type and acoustic output characteristics. Ensure the operating environment temperature remains within the specified -30°C to 65°C range. Confirm that the mounting hole diameter matches the 42.85mm requirement for proper installation. Cross-reference certification marks such as UL or cUL if required by local safety regulations for the intended application.

Selection Notes

Select this component when high-volume audible alerts are required in environments with standard industrial voltage levels. The wide voltage tolerance allows compatibility with various control circuits. Consider the physical dimensions and mounting style to ensure integration into existing panel layouts. Evaluate the slow pulse mode against continuous tone alternatives based on attention-grabbing requirements.
