Frequently Asked Questions
What is the function of the "transceiver integrated" design?
The transceiver integrated design means the single 16mm probe operates both as a transmitter and a receiver for ultrasonic signals, significantly saving space and simplifying circuit integration.
Is this probe suitable for outdoor and automotive environments?
Yes, its sealed and waterproof construction combined with a wide operating temperature range (-40°C to +85°C) makes it ideal for harsh outdoor environments, automotive parking sensors, and proximity sensing.
What does the directionality angle (X = 60 ± 10, Y = 60 ± 10) indicate?
This indicates the ultrasonic beam width in both horizontal (X) and vertical (Y) axes, providing a symmetric 60-degree detection zone suitable for accurate obstacle detection.
What type of terminal connection does this sensor probe have?
The probe is equipped with a pin tip connector, allowing straightforward through-hole soldering or direct mounting onto compatible PCB modules and sockets.
What are the typical applications for this 16mm ultrasonic sensor?
Common applications include automotive distance measurement modules, car reversing radar systems, smart home automation devices, water level monitoring, and industrial proximity switches.
