What do you call it?

Rick Densing · Jul 11, 2004

Just wondering

bernie_carlton · Jul 11, 2004

I call it a 'prox' when everyone knows precisely which type we're talking about. But otherwise I try to precede it with 'photo' or 'inductive' or 'capacitive' or even 'ultrasonic' depending on the sensing method.

If you were to tell me you were using a photo prox I wouldn't have a clue what you were talking about.

Another vote for "prox".

If I get more specific with the mechanical engineers, I get blank faced stares.

Rick: Good idea for a thread posting!

How about another one?

Is it a "photoeye", a "photosensor", a "photocell" or whatever else?

I've heard all the three above. There must be more.

If difuse I call it an eyeball, if send-receive, eyeballs

Must be an 'over the pond' thing - prox

Here in UK it is usually shortened to proxy switch

But the best I hear, and I hear it all the time from none technical people is 'magic eye'

I always know what they mean, but the times I hear 'I dont think that magic eye is working properly' hehehehehe

prox switch for inductive and photo eye for photo... never had much use for capacitive, but I guess that would fall under prox switch

Sometimes Goody it becomes.....

"That POXY switch!!!!"

P.S I am with Goody on this one - proxy switch.

I never heard Proxy until we had a job out east in Maryland. That was a standard term in that shop. We always used prox switch.

When I hear it, "proxy" it always connotes some sort of voting. I suppose in a fuzzy logig system, each proximity switch could have a weighted proxy?

Rick Densing · Jul 12, 2004

Locally, I have only heard "proxy" from grads of the milwaukee school of engineering.

I never use the term "proxy" when speaking of proximity sensors.

However, I do use the term "proxy". I use it when I write "shadow code" for existing outputs. I use the term "proxy" as it is defined.

Existing code...



  existing

   stuff

----| |----------( Y24 ) Forward Valve

Shadow Code...



    new

   stuff

----| |----------( C124 ) "PROXY" Forward Valve

After feeling comfortable with the Shadow Code I modify the existing code as follows...



  existing      USE

   stuff      NEW CODE

----| |---------|/|------+----( Y24 ) Forward Valve

               C300      |

  "PROXY"                |

   Foward       USE      |

   Valve      NEW CODE   |

----| |---------| |------+

    C124       C300

When I get the "hair"... I turn ON C300 to switch control of the valve from the old code to the new code.

Once I feel very satisfied with the new code I remove the old code and convert the C124 "Proxy" Output to the actual Valve Output.

So, no... I don't use "proxy" as some have indicated.

And I don't say "screwy-dwiver" either.

I usually say "prox".

Every once in awhile, I'll call it an
ECKO switch, just to watch the reactions.

David_Emmerich · Jul 12, 2004

1: I use the term PROX for mag or cap prox sw's.
2: I use the term PEE (Photo Electric Eye) for them.
3: It does help to mention the specific brand or model of PEE in use.

Around our shop, we use the term prox if it uses an inductive or capacitive field, reed switch or magnetic switch if it uses a magnetic field, and photo eye if it sends and receives a light signal (even if they are two separate devices). A photo cell, however, is not a sensor but a device that converts light into an electric voltage. But you have to keep an open mind when the mechanics say terms like switch, limit switch, Poke Yoke, and "The Efector" which is our predominant brand.

What do you call it?

What do you call it?

Prox

Proxy

Proximity Switch- I only use proper terms

What are you talking about?
