ZA028MDMP1

Alarms, Buzzers, And Sirens Overview

The ZA028MDMP1 is a piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting with terminal block connections. It operates on DC input within a voltage range of 16 to 28V and draws 40mA. The device emits a medium pulse tone at 3.3kHz with a sound pressure level of 75dB measured at 16V and 61cm. Its circular housing has a diameter of 30.74mm and a maximum installation height of 56.75mm. Certified by UL and cUL, it meets NEMA 3R, 4X, and 12 environmental protection standards.

Alarms, Buzzers, And Sirens Feature Summary

• Features an internal driver circuit for direct operation without external oscillators.
• Provides high environmental resistance compliant with NEMA 3R, 4X, and 12 ratings.
• Utilizes a piezoelectric transducer technology for reliable acoustic output.
• Includes top-mounted ports for directed sound projection.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix MDMP1 against the manufacturer's current datasheet to confirm terminal block orientation and lead configuration. Ensure the application environment remains within the specified -30°C to 65°C operating temperature range. Confirm that the required 75dB SPL at 16V meets the acoustic requirements of the installation site. Check for RoHS3 compliance if restricted substances are a concern.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a medium pulse tone is required for attention-grabbing alerts in industrial settings. The 30.74mm diameter fits standard panel cutouts associated with the ZA series. Choose this variant over continuous tone models if intermittent signaling is preferred. Ensure the power supply provides stable DC voltage between 16V and 28V to maintain optimal performance and current draw.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Mallory Sonalert ZA series, which offers various audible indicators for industrial use. The ZA series is known for robust construction and diverse mounting options. The ZA028MDMP1 specifically represents the panel-mount variant with terminal blocks, distinguishing it from PCB or bracket-mounted alternatives in the same family.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes within the ZA series include ZA028MDDL1 for continuous tone applications. Verify physical dimensions and electrical parameters before swapping. No other part numbers are confirmed as direct replacements in the provided documentation.
