Overview
The RDTE-2.700-8585-NS2 is an externally driven magnetic electromagnetic transducer manufactured by Raltron Electronics. It operates at a nominal voltage of 3.6V with a maximum current consumption of 100mA. The device generates an acoustic output of 85dB measured at a distance of 10cm from the source. Its fundamental operating frequency is 2.7kHz. The component utilizes surface mount technology, featuring solder pads for PCB attachment.
Feature Summary
- Externally driven magnetic transducer design
- Surface mount package with solder pads
- High sound pressure level output
Applications
- Electronic alarm systems
- Audible notification devices
- Consumer electronics audio alerts
Procurement Notes
Verify the specific ordering suffix and mechanical dimensions against the official Raltron datasheet before integration. Confirm that the driving circuitry can supply the required 100mA peak current at 3.6V. Ensure the PCB layout accommodates the surface mount solder pad footprint to guarantee reliable acoustic performance and electrical connection.
Selection Notes
Select this component when a high-decibel audible alert is required in space-constrained designs. The external drive requirement necessitates an accompanying driver circuit or microcontroller GPIO capable of sourcing sufficient current. Consider the 2.7kHz frequency response for human hearing sensitivity in warning applications.
Part Context
This part belongs to the RDTE series of magnetic buzzers from Raltron Electronics. These components are designed as active acoustic elements requiring external signal generation. They differ from self-oscillating buzzers by relying on an external square wave input to produce sound, offering flexibility in tone selection within the resonant frequency range.
Replacement Considerations
Consult the official Raltron cross-reference documentation for verified substitutes. Ensure any replacement maintains the 3.6V operating voltage, 100mA current rating, and compatible surface mount footprint.
