Ultrasonic Receivers, Transmitters

Ultrasonic Receivers, Transmitters Product Category Overview

1. Definition of Ultrasonic Receivers & Transmitters

Ultrasonic Receivers and Transmitters are specialized sensors within the broader Sensors & Transducers category, designed to emit and detect high-frequency sound waves (typically above 20 kHz) for precise distance measurement, object detection, and fluid level sensing. These components work in tandem transmitters generate ultrasonic pulses, while receivers capture reflected signals to calculate time-of-flight or signal attenuation, enabling non-contact sensing in industrial, automotive, and IoT applications.

2. Types of Ultrasonic Receivers & Transmitters

This category includes:
- Standalone Transmitters/Receivers: Compact modules for OEM integration.
- Integrated Transceiver Units: Combined emitter-receiver pairs for simplified design.
- Industrial-Grade Sensors: Ruggedized for harsh environments (IP67+).
- Analog vs. Digital Outputs: Select based on signal processing requirements.
- Frequency-Specific Models: Ranging from 40 kHz to 400 kHz for varying precision needs.

3. Key Purchasing Considerations

Application Fit: Match frequency (e.g., 58 kHz for liquid level control) and beam angle to your use case.
Environmental Durability: Prioritize waterproofing (IP rating) for outdoor/industrial settings.
Output Compatibility: Ensure alignment with your system s input (e.g., PWM, I2C).
Certifications: Look for CE, RoHS, or industry-specific compliance.
Pairing Consistency: For optimal performance, use matched transmitter-receiver sets from the same product line.

Ideal for robotics, parking assistance, and automated dispensing systems, ultrasonic components offer reliable, cost-effective sensing. Evaluate specifications against operational ranges and interference risks (e.g., ambient noise) to maximize ROI.
