Irritrol RS500 Wired Rain Sensor with 25 ft UV-Resistant Cable

The Irritrol RS500 Wired Rain Sensor stops scheduled irrigation when rainfall is detected, helping conserve water and protect landscapes. Its compact, durable housing and simple two-wire connection make installation quick. The sensor's reliable mechanical design minimizes false triggers and requires little maintenance once mounted.

• Adjustable rainfall sensitivity (3–25 mm / 1/8–3/4 in) lets you set the activation threshold for your site.
• Vent ring dry-out adjustment controls how long irrigation stays suspended after rain, from quick reset to extended delay.
• Includes 25 ft (7.5 m) UV-resistant white-jacketed cable; cable can be extended up to 100 ft using 18 AWG outdoor-rated wire for flexible placement.
• Works with normally open or normally closed sensor circuits and is compatible with most AC-powered controllers and timers.
• UV-resistant engineered polymer housing with gutter clip, surface-mount screws, and conduit adapter for multiple mounting options; UL-listed for dependable outdoor service.
