CT25E-16T75-1

Alarms, Buzzers, And Sirens Overview

The CT25E-16T75-1 is an externally driven magnetic sound transducer manufactured by Challenge Electronics. It operates on a rated voltage of 12 V with a current draw of 55 mA. The device produces a sound pressure level of 104 dB at 12 V and 10 cm distance, tuned to a frequency of 750 Hz. It features through-hole PC pin termination and measures 25 mm in diameter by 12.5 mm in height.

Alarms, Buzzers, And Sirens Feature Summary

• IEC-60601-1-8 compliant for medical audio signaling
• Externally driven magnetic technology
• Through-hole mounting via PC pins

Alarms, Buzzers, And Sirens Applications

• Medical equipment audio indicators
• Hospital alarm systems
• Diagnostic device signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix '75-1' against official datasheets to confirm the 750 Hz tuning frequency. Ensure compatibility with IEC-60601-1-8 standards if used in regulated medical environments. Confirm that the external drive circuit can supply the required 55 mA current at 12 V without exceeding thermal limits.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, medically compliant acoustic indicator is required. The 750 Hz frequency offers distinct audibility compared to higher-pitched alternatives. Consider the 25 mm form factor for space-constrained enclosures where through-hole assembly is preferred over surface mount options.

Alarms, Buzzers, And Sirens Part Context

This model belongs to Challenge Electronics' CT25E series of IEC-compliant sound transducers. The series is designed specifically for healthcare applications requiring reliable audio signaling. The '16T' designation typically indicates the magnetic driver type and terminal configuration within the product family.

Alarms, Buzzers, And Sirens Replacement Considerations

The CT25E-16T150-1 is a related variant within the same series but is tuned to 1500 Hz. Verify if the application requires the specific 750 Hz tone or if the higher frequency alternative is acceptable for system integration.
