SCE048MA3CK1B

Alarms, Buzzers, And Sirens Overview

The SCE048MA3CK1B is a piezoelectric buzzer from the SCE series by Mallory Sonalert Products Inc. It operates on an AC/DC input voltage range of 28 to 48V with a current draw of 40mA. The device produces a sound pressure level of 75dB at 28V measured at 61cm, emitting a frequency of 2.9kHz in a click pulse mode. It features terminal block termination and panel mount installation. The unit has a diameter of 42.85mm and functions within a temperature range of -40°C to 85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct connection
• Panel mount design with terminal block connections
• Capable of operating on both AC and DC power supplies
• Compliant with RoHS standards

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible alerts
• Machine tool status indication systems
• HVAC equipment alarm interfaces
• Automated manufacturing safety warnings

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic output characteristics against project requirements, as the datasheet indicates a 75dB rating at 28V. Confirm that the 28-48V input range aligns with the available power supply infrastructure. Ensure the panel cutout dimensions accommodate the 42.85mm diameter. Check for any regional compliance certifications required for the intended deployment environment before finalizing the order.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a robust industrial-grade indicator is needed for environments ranging from -40°C to 85°C. The internal driver simplifies circuit design by eliminating external oscillators. Choose this model over lower SPL variants if higher audibility is required without increasing voltage. Consider the terminal block termination style for secure wiring in high-vibration settings compared to wire lead options.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series, which offers larger form factors than the ZA series. It provides higher durability and wider temperature tolerance suitable for harsh industrial conditions. The series supports various tones and voltages, allowing customization for specific alert patterns while maintaining consistent mounting dimensions for easy integration into existing enclosures.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other SCE series parts like SCE048MD3SR4B for similar electrical specs but different tone profiles. Verify that replacement units maintain the same 42.85mm diameter and terminal block configuration to ensure physical compatibility without modifying panel cutouts or wiring harnesses.
