The MB7586 SCXL-MaxSonar-WRLT is a long-range, weather-resistant ultrasonic distance sensor with millimetre resolution. It detects the nearest target from 500 mm to 9,999 mm (approximately 10 metres) and provides output via analogue voltage, TTL serial, or pulse-width — making it versatile for a wide range of outdoor sensing applications.

Housed in a compact, rugged PVC enclosure rated IP67 for water and dust resistance, the sensor fits standard ¾-inch PVC pipe fittings for easy mounting. A self-cleaning transducer reduces the impact of condensation and frost during continuous operation in humid or enclosed environments.

Key Features

• 10-Metre Range – Detects targets from 500 mm to 9,999 mm
• 1 mm Resolution – High-precision distance measurements
• IP67 Weather Resistant – Rugged PVC housing, sealed against water and dust
