MB7489 Waterproof Ultrasonic Distance Sensor (50-500cm, 4-20mA, IP67)

The MB7489 is an industrial-grade waterproof ultrasonic distance sensor engineered for outdoor monitoring applications. Delivering precise measurements across a wide range, it suits makers, educators, and engineers building rugged sensing systems.

Extended 50 to 500cm range

The sensor reliably detects targets across a distance span of 50cm to 500cm. This makes it suitable for liquid level sensing, tank monitoring, and obstacle tracking.

Industry-standard 4-20mA output

Featuring a 4-20mA current loop interface, the module integrates smoothly with industrial control systems. This analogue interface provides stable signal transmission over longer cable runs.

Waterproof IP67 PVC housing

Built with a rugged PVC housing rated at IP67, the unit resists water ingress and environmental contamination. It is designed specifically for reliable operation in outdoor environments.

Precise 1.6mm resolution

With a measurement resolution of 1.6mm, the sensor offers fine-grained data for accuracy-critical tasks. It delivers consistent non-contact distance readings across its entire operating range.
