Overview
The SC110JWR is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 6 to 120 VAC or DC, drawing a current between 6 and 20 mA. The device produces a warble tone at a frequency of 2.8 kHz with a sound pressure level of 80 dBA. Designed for panel mounting, it features screw terminals for connection and functions within a temperature range of -30°C to 65°C.
Feature Summary
- Internally driven piezoelectric technology for direct AC/DC operation
- Warble tone output for distinct auditory alerting
- Panel mount construction with screw terminal connections
Applications
- Industrial equipment status indication
- Control panel alarm signaling
- Safety warning systems in machinery
Procurement Notes
Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure correct acoustic and electrical specifications. Confirm that the operating environment falls within the stated temperature limits. Check for any recent product change notices regarding dimensions or materials before finalizing procurement orders.
Selection Notes
Select this component when a continuous warble alert is required for industrial panels. Ensure the available space accommodates the 43 mm diameter and 1.41 inch height. Verify that the control circuitry can supply the necessary 6 to 20 mA current at the system voltage without exceeding the device ratings.
Part Context
This part belongs to the SC series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust piezoelectric construction suitable for harsh environments. The SC110JWR specifically provides a warble tone variant within this lineup, distinguishing it from continuous or pulse tone models.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Direct replacements must match the 43 mm diameter, 120V rating, and warble tone specification to maintain compatibility with existing panel cutouts and control logic.
