The Rain Bird RSDBEX RSD Series Wired Rain Sensor automatically shuts off your irrigation system when rainfall is detected, preventing unnecessary watering and conserving landscape health. Designed for dependable outdoor performance, the RSDBEX pairs easily with most 24 VAC irrigation controllers and is suitable for low-voltage pump start relay circuits. Moisture-sensitive disks respond to precipitation while an adjustable sensitivity dial lets you set the rainfall threshold to match local conditions.

  • Adjustable sensitivity: 1/8" to 3/4" (5–20 mm) for precise rain detection and fewer false triggers.
  • Durable construction: UV-resistant polymer sensor body with corrosion-resistant 5" latching aluminum bracket.
  • Flexible mounting: Includes 25 ft of #20, 2-conductor UV-resistant cable for versatile placement.
  • Electrical specs: Switch rating 3A @ 125/250 VAC; compatible with standard 24 VAC control circuits and pump start relays.
  • Certifications: UL/cUL listed and CE certified for reliable, safe operation.

Easy to install and simple to maintain, the RSDBEX ships with mounting hardware and clear instructions. The adjustable vent ring controls drying time so the sensor resets reliably after rain. Ideal for residential and commercial irrigation systems, it helps reduce wasted water and protect plants from overwatering.
