MaxBotix MB7563 SCXL-MaxSonar-WRLS Ultrasonic Sensor - IP67 PVC Housing, 30-500 cm Range

The MB7563 provides three simultaneous output formats: an analog voltage pin where the voltage scales linearly with distance, a pulse width output pin where the pulse length corresponds to distance, and a serial (RS232) TX pin that outputs ASCII character strings. You can use any single output that best fits your microcontroller (like Arduino) or PLC interface, without needing to configure the sensor.

The sensor's firmware analyzes all return echoes and selects the one with the largest acoustic amplitude. This allows it to ignore smaller clutter, like raindrops, foam, or debris, and reliably range the primary object, such as a liquid surface in a tank or a wall behind a fence. It is particularly beneficial in bin level measurement and outdoor environments where false targets are common.

Yes, the MB7563 is designed for harsh environments. Its IP67 rating protects the electronics, and running the sensor continuously generates slight heating at the transducer, which helps reduce the impact of condensation and light frost. For heavy icing, the self-cleaning transducer mechanism and advanced signal processing help maintain functionality, making it a recommended choice for tank level applications where icing can occur.

The sensor operates from a 2.7V to 5.5V DC supply. The average current consumption is approximately 68 mA during normal operation. It is compatible with common 3.3V and 5V logic systems, making it easy to power from a microcontroller board or a regulated industrial power source.

The sensor housing is made from PVC and features a standard 3/4-inch National Pipe Thread (NPT) straight male thread. This allows for direct installation into a compatible threaded hole or by using standard 3/4-inch NPT pipe fittings and mounting brackets commonly available in electrical and plumbing supplies.
