Description

NJF4070 Series is a sensor unit for high-resolution distance measurement, incorporating our 60 GHz Smart Sensor Micro Module, NJR4652. By utilizing proprietary signal processing technology, it delivers highly accurate distance measurement.
The lineup also includes a version equipped with a rectangular horn antenna, enabling users to choose the measurement performance that best meets their application requirements.
The interface is UART. In addition, its low standby current consumption makes it suitable for power environments utilizing solar batteries.
NJR4652 series will become NRND (Not Recommended for New Design), however, NJF4070 series will continue to be supplied.

Features

Distance measurement sensor using a 60 GHz device

Minimum distance step: 1.9 mm (with configuration limitations)

Short measurement cycle: 35 ms/frame

Low current consumption（15 mA in operation, 0.1 mA in standby mode）

Easy connectivity via UART interface

Key Applications

Water level measurement for rivers, reservoirs, irrigation systems, sea levels, and sewer manholes

Remaining volume measurement in silos and storage tanks

Non-contact measurement of powders and liquids

Distance detection in industrial machinery and equipment
