SCE120SA3DP2B

Alarms, Buzzers, And Sirens Overview

The SCE120SA3DP2B is a piezoelectric buzzer from the SCE series, designed for panel mounting with terminal block connections. It operates on AC input within a voltage range of 30 to 120V and draws 40mA. The device emits a soft tone at a frequency of 3kHz using a fast speed-up waveform. It features an internal driver circuit and provides a sound pressure level of 95dB at 61cm. Certified by UL and cUL, it functions reliably between -40°C and 85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driver circuit for direct AC connection without external components
• Produces a soft acoustic signal using a fast speed-up pulse waveform
• Constructed with piezoelectric technology for durable audible indication
• Includes UL and cUL safety certifications for industrial compliance

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring high-voltage AC signaling
• Machine tool status indicators
• Factory automation alarm systems
• Electrical enclosure monitoring devices

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DP2B confirms the fast speed-up waveform and soft tone characteristics against official Mallory Sonalert documentation. Ensure the operating environment remains within the specified -40°C to 85°C temperature range. Confirm that the 30-120V AC input matches the system power supply before integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a soft, distinct alert is required for high-voltage AC environments. The integrated driver simplifies circuit design compared to passive buzzers. Consider the 95dB output level for noise attenuation requirements in the installation area. Verify panel cutout dimensions accommodate the 42.85mm diameter housing.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction suitable for harsh industrial conditions. These devices are engineered for long-term reliability in continuous operation scenarios where clear auditory feedback is critical for operational safety.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with SCE120SA3SU2B for similar electrical specifications but different waveform characteristics. Verify compatibility with existing panel mounts and wiring configurations when substituting.
