Product Specification

Ultrasonic Proximity Sensor Module for Water Proof Types of Ultrasonic Sensors

HG-P40WP Ultrasonic Proximity Sensor Module Description

• Using only a single sensor(transceiver sensor) unit for both transmittance and receiving ultrasonic waves
• Convenient for distance measuring and object detection.
• Two types of transmit mode for convenience
  - Free Run mode : with a power supply, sensor/module itself transmits trigger and burst signal – for basic & stand alone application
  - External Trigger : External system(a controller or processor circuit) controls the trigger signals – for advance application such as multi-sensor system
• Input DC voltage is applicable in the wide range from 6 V to 15 V
• Output signal of 5V TTL level is applicable to processor circuit usage or controllers of industrial system.
• Four simultaneous output signals
  - Ultrasonic waveforms of received and amplified signals
  - Squared signals in TTL level corresponding to detected ultrasonic waveforms
  - Squared signal that the pulse-width is proportional to distance
  - Current signal (10 mA) is outputted when object is detected in a preset range
  - The preset of a maximum detection range is adjustable in the range from 0.5 to 6 m (typically 3 m in factory release)
※ The setting of a special detection range in distance is available for volume orders
• High performance ASIC Chip is mounted in the module for stable transmission and sensitive reception (Maximum amplification is about 5,000 times)
• Long distance detection is available by optimized design

HG-P40WP Ultrasonic Proximity Sensor Module Features
