Any ATO sensor alternatives for Apex?

[Sparkss]

I have an A3 with 1 MOS optical sensor that I use for a low level sensor in my sump. I use a float valve for my fill, so that is a measure of safety if/when the MOS fails. I would like to at least monitor my ATO reservoir and depending on cost add a high level sensor to my sump, so I was looking for sensor alternatives. Aside from being out of stock everywhere they are also $40 each.

If it is a matter of converting the wiring to match the plug that Apex uses, that is not a problem. I run my existing 12v ATO pump off of the 24v accessory output on the EB832 (using a microfit connector, buck converter and barrel connector). My reservoir unfortunately does not lend itself to any sort of float sensor. It is a 5g water jug/container that I designed and printed a screw cap for that allows the wires and return tube in/out and a threaded opening for a 1/2" barb fitting for filling it. So a magnetic solution, that can fit through a 2" top opening, is needed. I will eventually replace this with a larger reservoir, perhaps an RV water tank, but for now it is what I have to work with. Thanks in advance.

I like regular float switches wired into a breakout box. More reliable than opticals and cheaper too. The opticals require regular cleaning to work right and fail way more often.

I agree, but as I noted they are not currently an option. I am still searching around for some that might fit, but most w/ a mag mount are too large.

Anything preventing you from drilling a hole? These are super reliable for a high level switch.

Float Switch - Horizontal Mount

Recommended for water applications like level controllers, auto top systems or other aquarium uses Normally closed or normally open (see more) 14” leads (22 gauge wire) M16 straight threading - includes nut and silicon o-ring 5/8" Mounting hole required Mounts with wires outside of chamber...

Thanks, but no, I am not going to be drilling this container. It will have a purpose beyond it's current one when I eventually swap it out. And I am not looking for a high level switch, but am looking for a low level one for the reservoir. Unless you are recommending putting one in the sump and using the existing optical in the fill water container, which I had considered. I just need to then find a good mount for the float as where it goes there is not a good "lip" in the sump where I need to place it to clip it on. And I will not drill the sump wall. I have options along the lines of using a float in the sump, but need to finish wiring up/soldering the break out box before I give them serious consideration.

This is the one I use for mounting in my sump

Anything magnetic closer than the one I linked will affect the Reed and turn the float into a paperweight.

Thanks. I will look into both of those, although I am leaning towards that mag one.
