Frequently Asked Questions

What is the operating principle of the GU1812B-40TR sensor?

The GU1812B-40TR is an integrated piezoelectric ultrasonic transducer. It operates by converting electrical pulses into 40kHz sound waves (transmit mode) and then converting the reflected sound waves back into electrical signals (receive mode). The time delay between transmission and reception is used to calculate distance via the time-of-flight principle.

What is the maximum driving voltage for this ultrasonic transducer?

The transducer has a voltage rating of 120V. This refers to the maximum peak-to-peak driving voltage that can be applied to the transmitter element. For the receiver side, it indicates the signal level it can safely handle. Always consult the datasheet for specific drive circuit recommendations.

Can this sensor be used outdoors or in extreme temperatures?

Yes, the GU1812B-40TR is rated for an operating temperature range of -40°C to +80°C, making it suitable for outdoor, automotive, and industrial environments subject to wide temperature swings. Its construction is designed to maintain performance across this range.
