Rain Bird RSD-BEX Rain Sensor w/Aluminum Latching Bracket & Extension Wire

Product actually arrived early, was very easy to install and works perfectly.

This allows your sprinkler system to sense when rain has fallen and not water if you've recently received a lot of rain. This is our second unit. The first lasted several years before it quit working. Like that it won't over water when we've had a lot of rain and save in water bill.

These things really work. Don't be "that guy" whose sprinklers are on when it's raining...

I bought two of these sensors. One was for an experimental project and the other was for a DIG series 500 controller who's instruction manual suggested pairing it with either a Hunter Mini Click 2 or this product, a Rainbird RSD BEx rain sensor. It suggested above and beyond all the sensor be a normally open style switching/wiring configuration. Well not only did the DIG manual get it completely wrong about the normally open switching but so did the sellers listing. I ended up returning the one for the DIG controller, the seller accepted the return uncontested, postage paid. Still waiting for that return to finalise and the money to repost but Amazon has always done me right so I'm not trippin', just giving detail. I then ordered a Hunter Mini Click 2 and it worked just fine for a controller requiring normally open switching. If you find yourself in this same position remember it is the Mini Click 2 and it has 3 wires coming from it not just 2. You'll only be using 2 of them and you'll also know you have the correct one because it is about twice the price. Now, the one I kept is a normally closed and suitable for the experimental use I intended it for (either would have worked) and the unit seems well made and robust. It was easy to install and very simple to understand and operate. It came with some simple instructions and a quick internet search yielded a detailed manual regarding its feature set. Makes me wonder a bit why the seller would have it wrongly noted as a normally open when the literature available tells very clearly otherwise. My advice is edit your listing and include the exact model number and updated, correct technical specifications. You'll avoid confusion and end up selling more as a result. Hopefully someone finds this helpful. :)

This was very straightforward to install. Connect the two wires to the device on one end and the controller on the other, activate the sensor. It reliably measures rain, and my system delays watering on those days.

This product was exactly what we needed to help monitor our watering needs. The seller had it delivered quickly and wrapped very securely. Definitely recommend Sprinkler Parts Wholesale!

If installing on older model Rainbird controller, disconnect the TWO common wires (mine were white) from unit's zone(s) solenoid AND the motor switch and connect BOTH to the RSD. The RSD is nothing more than an ON/OFF switch. The instructions with the device makes it appear that you should only connect the common wire from the zone(s) solenoid. If you did this, what would happen when it rains enough for the RSD to work would be the zone(s) solenoid would shut off but your pump motor would still operate. The motor would probably burn out.

I had to return this as the cord was not long enough to reach outside from where my controller is located. The picture (since corrected) seemed to show it was the wireless version. Don't rely on my three star rating; I had to pick one because of the programming, but I never used the product.

Easy to install, connect and works great!

Compatible with Rainbird with a good length of wire

works perfectly

Dopo anni mi sono deciso di installarlo sulla mia centralina Rain Bird esp me, funziona alla perfezione , facile da installare e usare. Funziona anche con cavo giuntato e lungo circa 15\20 metri

L'importante per un ottimo funzionamento è tenerlo pulito
