Overview
The RDT-4.000-1375-NS1 is an externally driven piezo transducer manufactured by Raltron Electronics, designed for audio signal generation in alarms and sirens. It features a 13mm outer diameter with a height of 7.5mm. The component operates at a nominal frequency of 4kHz. It requires a drive voltage of 5VDC and draws a maximum current of 5mA. Acoustic performance includes a sound pressure level of 80dB measured at 5V from a distance of 10cm. The device utilizes through-hole PC pins for mounting on printed circuit boards.
Feature Summary
- Externally driven piezoelectric design for direct integration into alarm circuits
- High acoustic output efficiency providing clear audible signaling
- Robust mechanical construction suitable for standard PCB assembly processes
Applications
- Electronic alarm systems
- Audible sirens and warning devices
- Consumer electronics requiring acoustic feedback
Procurement Notes
Verify the specific acoustic output requirements against the datasheet specifications before procurement. Ensure that the driving circuit can supply the required 5VDC and 5mA current limits to prevent damage. Confirm that the through-hole pin configuration matches the target PCB footprint. Check for any environmental ratings if the application involves extreme temperatures or humidity.
Selection Notes
Select this component when a compact 13mm piezo transducer is required for audible alerts. Consider the 80dB SPL rating for volume needs relative to the enclosure size. Evaluate the 5V operating voltage against the system power supply rails. Compare dimensions against available space constraints on the circuit board layout.
Part Context
This part belongs to Raltron's line of piezo transducers used in audio products. It is distinct from their crystal oscillators and resonators. The model number indicates specific physical dimensions and acoustic characteristics within the product family. It serves as a passive acoustic element driven by external logic or amplifier circuits.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacements must match the 13mm OD, 7.5mm height, 4kHz frequency, and through-hole pin configuration. Verify electrical compatibility with the existing driver circuitry.
