12v magic eye sensor

[Justme]

Yes there is that but then i may need some technical help aswell on this project and i hate it when people ring me and i spend half a hour explaining all the pros and cons and then find out they ordered somewhere £1 cheaper!

I'm not looking to cheap out on this really it will be used by farmers in tough conditions and I'd like them to get a good name for reliability hopefully!

Will farmers pay the premium for quality parts?

What would be the proper name for a sensor that i need..

12v input
Needs to trigger a 12v output when something passes with 300mm or so of it
Can't have a pair of sensors either side with a light beam between them needs to be just the one side
Think of a 500mm passageway and i need to trigger a air solenoid to open when something goes down the passageway within say 0.5 seconds

For anyone interested I'm building a air powered sheep clamp for general tasks foottrimming etc but would like it to shut automatically when a sheep runs through so 1 person can use it on their own

Tepari sheep handler on youtube is what I'm making only a slightly simpler version as that one is £25k

If you're going to use an air solenoid, can't you simplify things (avoiding the use of electronics) and use a manually activated valve? Will you always have access to air and power? It's been a long time since I did foot trimming (used to do several hundred at a time, out of windswept Salisbury Plain) and I don't envy you.

How many times was it moved in a day, hit by tractors, got **** and ****** on, left out in rain for months of the year, bounced over fields on trailers with limited suspension ect ect.

The two blanked out parts not too much but it was installed in a location on a rickety mast that got hit by high winds, temperatures, rain and dust storms daily for 10 years. Not too bad that for a system that wasn't protected against water and dust ingress apart from having a sun /rain hat installed over it.
