MaxBotix MB1240 XL-MaxSonar-EZ4 High-Performance Ultrasonic Sensor Module
The MaxBotix MB1240 XL-MaxSonar-EZ4 is a high-performance ultrasonic distance sensor module offering a 20-765 cm range with 1 cm resolution. It provides three simultaneous output options (Analog Voltage, RS232 Serial, and Pulse Width) for seamless integration with microcontrollers like Arduino, Raspberry Pi, and industrial PLCs.
Features
- High-performance ultrasonic ranging with a 20-765 cm (7.65 m) detection range and 1 cm resolution.
- Triple-output interface: Analog Voltage, RS232 Serial (TTL), and Pulse Width (PWM) for maximum compatibility.
- Advanced noise rejection with real-time automatic calibration for voltage, humidity, and ambient acoustic conditions.
- Compact, lightweight PCB design (22.5 x 20 mm) with integrated mounting holes for easy installation.
- Designed for indoor applications requiring reliable detection of larger objects with minimal dead zone.

The MB1240 XL-MaxSonar-EZ4 utilizes a 42 kHz ultrasonic transducer to provide precise, non-contact distance measurements. Its advanced firmware incorporates real-time waveform signature analysis and continuously variable gain to deliver virtually noise-free readings, even in electrically or acoustically noisy environments. This makes it suitable for applications where consistent, reliable data is critical.
Engineered for indoor use, the sensor features a narrow detection beam pattern, the narrowest in the XL-MaxSonar-EZ series, which helps isolate targets and reduce clutter from surrounding objects. The module’s real-time background automatic calibration continuously adjusts for changes in supply voltage and environmental conditions, ensuring stable long-term operation without manual intervention.
