Data Sheet
Model : HG-P40 Series
Ultrasonic Proximity Sensor & Module
▣ Description
• Using only a single transceiver sensor unit for transmit and receive signals.
• Convenient for distance measuring and object detection.
• Two types of transmit mode for convenience.
− Free Run : With a power supply, sensor transmits trigger and burst signal itself –
for basic application
− External Trigger : External system(controller or processor circuit) controls the
trigger signals – for advance application(distance measure)
• Two types of input power – Low(5V) for processor circuit usage and High(12V) for
controllers.
• Four different output signal (simultaneously).
− Real time ultrasonic wave amplified from actually received ultrasonic. (for sound
pressure measuring)
− Real time TTL level square signal(Square Wave) of detection signal. (for robots)
− Distance pulse width signal which is proportional to the nearest object from the
sensor. (for robots and distance measuring)
− Proximity output signal(10mA current) within the preset range(0.5~4.5m) (for
industrial use)
− Preset range is adjustable from 0.5 to 4.5 m. (factory distance preset available
for volume orders)
• High performance ASIC Chip for stable transmission and sensitive reception. (Max.
approx. 4,000 times amplification)
