Easily Installs on Any Automatic 
Irrigation System…
Simple to add on to an existing or new installation
The Mini-Clik
®
 is versatile enough to work with all 
popular irrigation controllers. The Mini-Clik is available 
in two versions. One is wired for “normally closed” sen-
sor terminals and the other is wired for “normally open” 
sensor terminals. Each unit will have two wires attached 
to it, connected to a 25-foot extension.
Available in 24 Volt and 110/220 Volt 
UL Listed Models…
Four different models to accommodate your 
particular wiring needs
Mini-Clik – The standard 
“normally closed” Mini-Clik 
model for use on most 24 Volt 
applications.
Mini-Clik-NO – The standard 
“normally open” Mini-Clik 
model for use on most 24 Volt 
applications.
Mini-Clik-C – Features a 
½" female threaded inlet at 
the bottom to accommodate 
conduit.
Mini-Clik-HV – The C model 
with added code approved liq-
uid-tight electrical fittings for 
110/220 Volt wiring applica-
tions and systems using pumps 
drawing less than 10 amps 
peak. Also includes 18 inches 
of 16 AWG wire. Ready to 
mount on any standard junc-
tion box. 
Constructed of High Impact Thermoplastic…
Dependable operation built to last
The Mini-Clik is constructed of heavy-duty materials 
including a thermoplastic that can withstand all ex-
tremes of weather from direct scorching sun to freezing 
ice storms.
Maintenance-Free Patented 
Sensing Mechanism…
No callbacks, set it and forget it
Unlike other rain sensors that use collection cups, the 
Mini-Clik does not collect debris, so it does not require 
cleaning. And, for those in cold climates, the Mini-Clik 
does not have to be removed or covered for “winteriz-
ing” purposes. This means no required maintenance for 
the unit and no callbacks to clean it.
The sensing mechanism is in-
genious but simple. Discs absorb 
water and then expand propor-
tionally to the amount of rainfall 
that fell (e.g., a small cloudburst 
would result in little absorption, 
a thunderstorm with 2" of rainfall would lead to more 
absorption and thus more expansion). As the moisture-
laden discs expand, they eventually activate a switch 
that interrupts the circuit from the controller to the 
valves. As the discs dry out, they contract and release 
the switch.
5-Year Warranty…
Hunter Industries backs up its products
A full five-year warranty by Hunter communicates to 
our customers that the Mini-Clik is a rain sensor that 
stands up to the environment. The end-user can be as-
sured of a quality product with a guarantee of depend-
able operation.
Adjusts to Actuate at Various Rainfall 
Quantities…
Versatile and accurate
Depending on local conditions, the 
Mini-Clik can keep the irrigation 
system from starting or continuing 
after rainfall quantities of 
1
⁄
8
", ¼", ½", 
¾", 1" (3 mm, 6 mm, 13 mm, 19 mm, 
25 mm). To adjust it to the desired 
shutoff quantity, rotate the cap on 
the switch housing so that the pin are 
located in the proper slots.
