Description

The HY40A12T09-1 is a piezoelectric ultrasonic transmitter that generates high-frequency sound waves at 40kHz, well above the human hearing range. It operates on the principle of piezoelectric transduction, where an applied AC voltage causes the ceramic element to vibrate and emit ultrasonic pulses. This dedicated transmitter is designed for systems where separate transmit and receive elements are required for improved performance or specific beam-forming applications.

Constructed with a durable housing, this transducer is rated for operation in environments from -25°C to +60°C, making it suitable for both indoor and protected outdoor use. Its plugin design facilitates straightforward mounting and connection to custom driver electronics, typically requiring a pulsed or continuous AC signal at its resonant frequency for optimal efficiency.

Key Features

  • Dedicated 40kHz Ultrasonic Transmitter for precise pulse generation.
  • Open plugin form factor (12x9mm) for easy integration into custom enclosures.
  • High-performance piezoelectric ceramic element for efficient acoustic energy conversion.
  • Robust construction ensures stable operation across a -25°C to +60°C temperature range.
  • RoHS compliant materials meet international environmental standards.
  • Designed for compatibility with standard ultrasonic driver and amplifier circuits.

Applications

  • Custom ultrasonic distance measurement and ranging systems.
  • Industrial object detection and presence sensing in automation.
  • Robotics navigation and obstacle avoidance subsystems.
  • Liquid level sensing in tanks and reservoirs.
  • Parking assistance and vehicle proximity detection systems.

Frequently Asked Questions

What is the operating voltage for the HY40A12T09-1 ultrasonic transmitter?

The datasheet lists a voltage rating of 120V, which typically refers to the maximum driving voltage for the piezoelectric element. In practice, it is driven by an AC signal at its resonant frequency (40kHz) from a driver circuit. Always refer to the specific driver IC or circuit requirements and do not apply a static DC voltage directly.

How do I connect and drive this open ultrasonic transmitter?

This is a plugin-style transmitter with two leads. It must be connected to an ultrasonic driver circuit that generates a pulsed or continuous AC signal at 40kHz. Common driver ICs include the MAX232 or dedicated MOSFET-based circuits. The transmitter acts as a capacitive load, so the driver must be capable of supplying sufficient current at the resonant frequency.

Can this transmitter be used as a combined transmitter/receiver?

No, the HY40A12T09-1 is specified as a dedicated transmitter. For systems requiring both functions, you would pair this with a separate ultrasonic receiver (like the HY40R series). Using a dedicated pair can improve system performance by allowing independent optimization of transmission power and reception sensitivity.
