As the demand for miniaturization and high reliability in medical technology grows, Hunston Electronics is proud to introduce the SMT5020T Series Electromagnetic Transducer. This high-performance component is engineered to meet the stringent requirements of modern clinical and portable medical equipment.
Core Features & Technical Strengths
- Ultra-Miniature Form Factor: Measuring only 5 x 5 x 2 mm, its ultra-thin profile allows for seamless integration into space-constrained designs, making it ideal for the next generation of handheld and wearable medical instruments.
- High-Output Acoustic Performance: Driven by a rated voltage of 3V, the transducer delivers a stable resonant frequency of 4000Hzand a Sound Pressure Level (SPL) of 80dBA at 10cm. This ensures that critical alerts are audible even in busy hospital environments.
- Versatile External Drive Design: As a passive (externally driven) transducer, it offers engineers full control over tone and rhythm by adjusting the input signal, enabling customized alarm sequences for different medical conditions.
- Robust & Reliable Construction: Encased in heat-resistant LCP (Liquid Crystal Polymer), the device supports standard SMT reflow soldering and operates reliably between -20°C and +70°C, ensuring long-term stability in clinical settings.
Critical Applications in Medical Technology
In healthcare, where equipment failure is not an option, the SMT5020T series serves as a vital alert mechanism for:
- Wearable Health Monitors: Providing low-power notification for glucose meters or heart rate monitors when measurements are complete or thresholds are exceeded.
- Infusion Pumps & Ventilators: Generating clear audible alarms for fluid depletion or system malfunctions in life-critical equipment.
- Portable Diagnostic Tools: At just 2g, it minimizes device weight, making it perfect for portable ultrasound scanners and point-of-care testing (POCT) analyzers.
