Hunter Mini-Clik™ wired rain sensor (normally open) automatically prevents scheduled irrigation during rainfall, helping conserve water and protect landscapes. Built for reliable, low‑maintenance operation, it mounts easily and connects to standard irrigation controllers.

  • Adjustable shutoff: 1/8"–3/4" (3–19 mm) rainfall sensitivity for tailored protection.
  • Complete install kit: includes 25' (7.5 m) of 20 AWG wire and aluminum mounting bracket for quick mounting.
  • Normally open (NO) configuration: third lead provided for open‑circuit controller setups.
  • Durable design: debris‑tolerant sensor with optional stainless steel sensor guard for commercial sites.
  • Electrical rating: designed for 24 VAC circuits; switch rating 3 A for reliable switching.
  • Reset control: adjustable vent ring slows or speeds the hygroscopic disc drying time to match site conditions.

Wiring is straightforward — connect the Mini‑Clik to SEN or COMMON terminals per the installation guide. Detailed wiring diagrams, spec sheets, and installation cards are available in the product documents. Backed by Hunter approvals (UL, cUL, FCC, CE, RCM) and a 5‑year limited warranty, the Mini‑Clik NO delivers proven rain detection and simple integration with most irrigation controllers.

Frequently Asked Questions

How do I wire the Mini-Clik NO to my controller?
Connect one sensor lead to COMMON and the NO lead to the SEN terminal per the installation diagram; use 24 VAC circuits only.
What does "normally open" mean for this sensor?
The NO model provides a separate lead for open‑circuit controller setups; use the third wire when your controller requires an NO contact.
How do I adjust the rain shutoff sensitivity?
Rotate the cap to choose 1/8", 1/4", 1/2" or 3/4" (3–19 mm) shutoff and use the vent ring to slow reset.
Is the Mini-Clik compatible with my irrigation controller?
Yes — the wired Mini‑Clik connects to SEN/COMMON terminals and is compatible with most controllers, including Hunter models.
