Product Introduction
Korean Hagisonic Ultrasonic Proximity Sensor Module HG-P40 Series Description:
• Uses only a single transceiver sensor unit to send and receive signals.
• Convenient for distance measurement and object detection.
• Provides two transmission modes for convenience:
• Free-running: When connected to power, the sensor itself sends trigger signals and burst signals - for basic applications
• External trigger: External system (controller or processor circuit) controls the trigger signal – for advanced applications (distance measurement)distance measurement)
• Two input power sources – low voltage (5V) for processor circuits, high voltage (12V) for controllers.
• Four different output signals (simultaneously).
• Amplifies the actually received ultrasonic waves in real time (for sound pressure measurement)
• Real-time TTL level rectangular wave (square wave) of the detection signal (for robotics)
• Pulse width signal proportional to the distance from the sensor to the nearest obstacle (for robotics and distance measurement)
• Proximity output signal (10mA current) within the preset range (0.5~4.5m) (industrial use)
• The preset range can be adjusted between 0.5 ~ 4.5 m (factory can preset the distance under bulk orders)
• High-performance ASIC chip for stable transmission and high-sensitivity signal reception (can amplify up to approximately 4,000 times)

Korean Hagisonic Ultrasonic Proximity Sensor Module HG-P40 Series Part Description:
① Ultrasonic sensor unit: Ø16 open-type sensor with conventional directivity (approximately 65~75˚).
② Power selection PAD (J2): Low voltage (5V) – requires soldering, high voltage (6~16V) – no soldering required (in this case, recommended voltage is above 6.5V).
③ Proximity detection LED: When an object enters the preset range, the red light turns on and generates a 10mA output signal.
④ Output terminal: Generates three different outputs simultaneously. (See P2 and P6)
⑤ Receiver sensitivity adjustment VR: The gain value of the preamplifier is adjusted within the range of 0 ~ 4,000x. (Factory default option: 2,000X)
⑥ ASIC chip: Versatile 48-pin chip (Hagisonic product)
⑦ Distance range adjustment VR: Range is 0.5 ~ 4.5m
⑧ Ultrasonic frequency adjustment: Factory adjusts the device to optimal performance (never adjust this!)
⑨ Input terminal: Power, external trigger input, and proximity output signal (10mA current) terminals (see P2 and P6)
Transmission mode selection PAD (J1):
- Free-running mode: requires soldering; generates approximately 10 ~ 15 pulses per second (factory option: soldered)
- External trigger mode: no soldering; requires external TTL level pulse transmission. (Can reach 1~100 per second, but the recommended value is 10~30 per second) (Recommended pulse width: 0.5~1mS)
