SC110H

Overview

The SC110HPR is a piezoelectric industrial buzzer from the Mallory Sonalert SC series. It operates on 30-120V AC/DC with a rated current of 20 mA. The device produces a fast pulse tone at 4500 Hz with an acoustic output of 80 dBA. It features screw terminals for connection and panel mount installation. Physical dimensions are 42.85 mm x 33 mm, with a diameter of 43 mm and height of 1.41 in (36 mm). Weight is 45 g.

Feature Summary

• Piezoelectric construction for reliable audio indication
• Fast pulse tone generation capability
• Screw terminal electrical connections
• Panel mount mechanical installation

Applications

• Industrial alarm systems
• High voltage equipment status indication
• Control panel audio alerts

Procurement Notes

Verify the specific suffix against official documentation to confirm functional attributes such as tone type and certification. Confirm that the required operating voltage range matches the application supply. Check for RoHS compliance status if environmental regulations apply. Ensure mounting hole dimensions align with the panel design specifications.

Selection Notes

Select this component when a high-frequency fast pulse alert is required for industrial environments. The 120V rating allows direct connection to standard control voltages without external drivers. Verify that the 80 dBA sound pressure level meets audibility requirements for the installation site noise conditions.

Part Context

This part belongs to the Mallory Sonalert SC series of industrial buzzers. These devices are designed for rugged applications requiring durable audio signaling. The series utilizes piezoelectric technology for consistent performance across varying temperatures and voltages within the specified operating range.

Replacement Considerations

SC110DPR offers similar fast pulse characteristics but operates at 1900 Hz with CUL approval.
