Stop wasting water on rainy days — the Hunter® Mini-Clik® rain sensor pauses your irrigation controller the moment accumulated rainfall hits the threshold you set, and lets it resume on its own once the discs dry out. It’s the simplest rain sensor Hunter sells: hard-wired with 25 ft of UL-approved sprinkler control wire, an aluminum extension arm to keep the sensor in open sky, and a rugged polycarbonate housing that holds up in the elements for years.

Why Irrigation Pros Pick the Mini-Clik

• Adjustable shutoff threshold — 1/8 in. to 3/4 in. of accumulated rainfall, set with a twist of the cap
• Debris tolerant — reliable operation without nuisance shutdowns from leaves, dust, or insect intrusion
• Hard-wired install — 25 ft (7.5 m) of 20 AWG sheathed, two-conductor, UL-approved wire shipped with the sensor
• Aluminum mounting bracket included — clamps to a fence post, gutter, or eave with the sensor held in open sky for accurate rainfall reading
• Rugged polycarbonate housing with metal extension arm — rust-resistant and built for buried-eave or full-sun service
• Compatible with most Hunter and third-party controllers — any 24 VAC controller with a normally open or normally closed sensor / rain-switch input
• Reset behavior: approximately 4 hours under dry, sunny conditions after a rain event; up to ~3 days when fully saturated
• 5-year manufacturer warranty

Where It Shines

• New residential or light-commercial irrigation builds where the controller cabinet is close enough to run sensor wire to a fence or eave
• Service calls swapping a failed rain sensor on an existing Hunter Pro-C, X-Core, X2, or I-Core system — same SENS terminal wiring
• Municipal water-conservation programs that mandate a rain shutoff on every irrigation system
• Retrofitting an older controller that has a SENS input but no current sensor wired in — Mini-Clik is the lowest-cost path to compliance

Wiring — Quick Overview

Two color-coded leads from the sensor connect to the controller’s SENS terminal pair (Hunter controllers) or break the valve common on controllers without a dedicated sensor input. The default switch state is normally closed — current flows in dry weather and the controller waters normally; when rainfall trips the disc stack, the switch opens and the controller treats the sensor as “active”, suspending the schedule. A normally-open variant ships as MINI-CLIK-NO if your installation needs reverse-polarity logic.

Compatible Controllers

The Mini-Clik works with every modern Hunter controller, including ACC, ACC2, HC, HCC, HPC, I-Core®, ICC2, MCC, Pro-C®, Pro-HC, X2, X-Core®, XC Hybrid, NODE, NODE-BT, and WVC. It also works with any 24 VAC controller from Rain Bird, Irritrol, Toro, Orbit, or other vendors that accepts a normally open or normally closed rain switch on its sensor terminal. On controllers without a SENS input, splice the sensor in series on the valve common (a standard install method covered in any rain sensor manual).
