Hi,

I want to use this limit switch "on table".
Meaning, I have this component and want to count the times I "close" it.
I'm gonna use a cartridge with mechanical set up which close the limit switch and release it.

There is any ideas.
I thought to do it with an Arduino, but how to start:-(

Moreover, maybe i need to add memory component to my set up.

Any idea will be blessed.

Thx a lot !!
 

Hi,

What's a LS-11D switch?
And what's exactly the problem?

Please don't ask global questions. Show your own effort instead.
What have you done so far?
What documents did you read?
What language and what compiler do you use?

Hi,

Sorry about it..
LS-11D is a limit switch.
What i have done so far:
I connect the limit switch to a breadboard with 24V PS pull up(5k ohm TH resistor)

The limit switch can be connected N/O or N/C.
I choose to work with NO.

The limit sw is inside a closet with a drawer (cartridge).
I need to count the times I close the drawer(when shortened it to GND)

I thought do not use with any compiler.
I found H7EC-NV-BH Omron counter that can help me to finish the set-up.

If needed, I can add/use FPGA or Arduino to my set up.

Best regards.
 

Hi,

since you don´t post (a link to) the datsasheets, I have to ask you:

What are the Omron counter operating input levels?
..and what´s it imput impedance / resistance/current?

Do you have a scope or at least a DVM to verify the signal and power supply levels?

Klaus
 

Hi,

the input impedance is 4.7k and according to my calculation the voltage will be 11.6V (high logic is 4.5-30V, low logic 0-2v)

Here the datasheet link:
**broken link removed**

pls refer to H7EC-NV-BH (pg. 2-7)

I still didn't order it yet.
So i cannot attach any scope images..

It seems it will be working well..

BR,

Hi,

with the given informations: I agree.

Not knowing about expected switching / counting speed, wiring and noise.
