Hall Effect Current Sensor

Howdy all,

I have been trying to locate a supplier for this type of Hall Effect current sensor...



The picture comes from the Hall Effect entry on Wikipedia and I have spent about a day looking around the Internet looking for ones exactly like this without success. It's ideal for my application because one can use a normal servo extension cable to wire it up to a board.

Anyone got any clues where they can be obtained?

Cheers,
Nigel

No Nigel, I can't find one exactly like that.
I would imagine it'll only be a generic picture of one that some bloke found in his drawer. There are zillions of makes.

There are pages and pages of the things in Farnell, RS and Digikey.

or you could look on a specialist site like:
http://www.hallsensors.de/
Chen-Yang is a traditional German name.

But unless someone recognises it, or has 10 hours to spare, then get Googling.

Do you even know the spec you really need? Or is it that specific one you want?

Hall effect sensors

Goto RS components and wander through their listings for hall effect sensors. It won't take you more than an hour or so, " 'cause they got pretty pictures of em to look at".
I have played with a honeywell unit, the CSNP661 from RS or another on worth having a look at is the Allegro ACS750.
What are you doing with it?

Hi,

Thanks for the replies.

I am maiking a power meter by measuring current and volts delivered by a battery. This little gadget is ideal because it can neatly go on a lead - many of the ones I have seen are meant to be PCB-mounted.

Cheers,
Nigel

Hi Myc,

Yes, that's what I tried with no luck. I even tried with using search terms derived from the description given in the Wikipedia caption but without any luck. Very odd...it's the sort of thing you'd have thought it would be easy to find.

Cheers,

This looks like a simple (typical) current transformer. I don't understand the "Hall Effect Sensor" aspect of this. Aren't Hall Effect devices for sensing magnetic fields. I know current transformers relate the magnetic field around a current carrying conductor to the crrent in the conductor, but I have never heard them called "Hall Effect Sensors"

Have you tried searrching Digkey or Mouser? That would give you a manufacturer.

Nigel, when you say "Yes, that's what I tried with no luck", do you mean you had no hits (I got almost 2,000,000 for "current sensor") or do you mean that Google didn't magically find that particular one?

[Google is neither 'my friend' nor clairvoyant]

Tip: Define your required specification and look in Farnell, RS, Digikey or your preferred electronics retailer. You'll find something that suits. The price might hurt. If so try Ebay.

With the greatest respect I honestly don't think people, with the best will and generosity in the world, are going to spend hours looking for something that probably won't be photographically identical to that piccy. :) (Unless they are at a loose end or their mother-in-law is visiting).

esoter: if there is a strong enough magnetic field kicking around then a Hall Effect sensor can sense it. That's it's job. Look 'em up in Farnell etc. etc. They've been around for donkeys years. You'd have a bit of trouble using a coil to pick up a DC current in a wire don't you reckon?
http://en.wikipedia.org/wiki/Hall_effect - halfway down the page. If you wish to correct the entry then it is up to you, but I think you may be un-right.

Dippy,

Yes, just like you I got loads of hits but after a day of looking (yes, I spent absolutely ages looking through the hits) I had no luck. I just wondered if anyone had seen one like the one in the photo. I don't need something absolutely identical but I do need something that is clearly intended to go at the end of a flying lead and not onto a PCB. The one in the picture exactly suits my purposes and I assumed that if it had a picture on Wikipedia it would be reasonably well-known. I thought that perhaps there might be an important search term that I wasn't using.

Cheers,
Nigel

Thanks Derek for the link, I have a app thats needs one of these. Have been playing with current sense R's but this device will be better I think.
