I’m looking for the best available replacement for the photoelectric Beam switches used for leveling on MPH & 300A. I think the EPOCH controllers used the same ones too. The original ATC part number is 7253br4x4nlx. I couldn’t find them in any Adams catalog so I ordered from Sees. The brand is LANBAO and they work but seem to be way more sensitive and less consistent than the originals. They also came with their own reflectors and it has been suggested to use them, but I’d rather find a more direct replacement.

Thanks for any advice.
