For saleSMC Digitale vacuum switch

Sold…

Thanks Michiel,

switch / sensor works perfect.
I always thought that there were no leaks when I use my analog gauge, a am sure this sensor will drive me crazy… this thing will not lie about leaks, I see immediately when there is even the smallest leak.

I am surprised, for the first time I see that the even the smallest leak has great effect on high vacuum. It is only possible to reach high vacuum when you dont have leaks …

I know it is “old news” but I just want to share.

Hi can you share how you connect it to your vacuum
I’m looking to add one to my system but I would like to see how and where to put it
Thank you

If somebody is interested I still have one switch. I also have used ones
SMC zse40f for €50 excl. shipping.

Hi Michiel, what are the differences between ZSE50F-02-62L and zse40f?
I would like to use it to controll vacuum level and turn on and turn off a pump

You can find both datasheets on the internet to compare.
related to the datasheets I don’t see the difference. same range etc.

Both are applicable for your needs I think.
you also need a solid state relais or a (small) mechanical relais. (max 80mA)

The difference is that one (new one) has a filter in it and the other one doesn’t.

Added a new switch.
