MB7789 Industrial Ultrasonic Distance Sensor (50-500cm, 4-20mA, IP67)

The MB7789 is a rugged industrial ultrasonic distance sensor designed for precise long-range measurement in demanding environments. Featuring an industry-standard 4-20mA output and an IP67-rated enclosure, it suits makers, engineers, and students developing outdoor telemetry or industrial automation systems.

Broad 50 to 500cm measurement range

The sensor measures distances reliably from 50cm up to 500cm. This extended detection envelope suits applications such as tank level monitoring and long-range obstacle detection.

Industry-standard 4-20mA current loop

Distance readings are transmitted via a robust 4-20mA analogue current loop. This interface provides strong noise immunity over long cable runs and connects directly to industrial PLCs and monitoring equipment.

Precise 1.6mm measurement resolution

The unit delivers a fine resolution of 1.6mm across its operational span. This level of precision ensures accurate tracking for fluid levels and positioning targets.

Weatherproof IP67-rated housing

Constructed inside an IP67 sealed housing, the sensor is protected against water and dust ingress. It is built to withstand harsh outdoor conditions during continuous monitoring deployments.
