Know of any "top looking" modulated IR receivers?

varnon

Hello all,

I am using infrared beams in many of my projects lately. Sometimes I really like side-looking IR receiver, but there are times that a top-looking receiver might be nice. I have seen top-looking or 5 mm LED casing photoresistors and phototransistors, but the only modulated IR receivers I seen are side-looking. Has anyone see a top-looking modulated IR receiver? Our laboratory recently got a 3D printer, and although I can incorporate a nice square slot into many of my projects to accommodate the the modulated IR receivers, it would be much easier to drill (or print) a 5 mm hole like I can for the IR LEDs. Am I out of luck?

Thanks

I have a couple nice dometops I got from Ebay China years ago. They work great, I've built them into a few projects, but I do not know their number or specs. I keep looking on Ebay but have not found them again. I can spare two if you need them. Assuming I can find them.

Otherwise, get a side-looker (a dime a dozen) and fold them over.

Weirdly, "The Shack" still sells these: http://www.radioshack.com/product/index.jsp?productId=2049727 But I think that you're looking for a smaller overall package, so these probably won't do.

A round LED casing is going to be very hard to find, but you can get SMD models that are designed for both side/top mounting, and there are also ones with single domes, which could sit behind a round hole.
All the volume is in SMD, these days, so best to use that if you want reliable supply.

I think that these http://www.vishay.com/docs/82491/tsop382.pdf are made for both horizontal or vertical mounting. The specs are given for both directions and Digikey has them in stock.

Varnon : After searching a while, I finally found exactly ONE remaining lot of the rare round types 10 pc on Ebay and PM'ed you. Approx 5 mm. If you want them, act fast! I'll buy them if you hesitate...

Edit: They are also on Amazon, where I found this pinout description: Starting from the flat side: signal out, ground, V+.

Someone bought the last ten today, hope it was you Varnon. If not, you can find them for a bit more on Amazon. Search for PIC-0038N

Erco:
That looks great! I don't want to invest too much in a "hard to find" part, but 20 will last me for a good while. I got the bunch from Amazon, forgot to hit check out last night...
My lab mate might have bought the ones from ebay. Either way, we are set for a while.

Wass:
That actually is a neat mount, but yeah it is still a bit bulky. After you mentioned that part I found some other mounts like it. I don't know if I could bring myself to buy something at radio shack, aside from last minute resistors and wire.
Also, you are totally right, the TSOP38240 should work great. I didn't notice on the data sheet that it mentions both horizontal and vertical detection. I am going to get some of these two. That form factor seems pretty common. Also, pretty cool that Vishay offers receivers for different frequencies. I wonder if I could do something fun with that.

jmg:
You are right, SMD is a good option. I'm trying to avoid it for now because I don't want to invest in another skill/tool set for SMD and printing circuit boards, and I don't want my colleagues to need that skill/tool set either. I do a little bit of SMD work, it isn't that bad. But I think I would prefer through-hole when ever possible.

Thanks a bunch guys, this has really helped me out.

Radio Shack is $0.49 cheaper and available on hang tags.

That's $5 for a 10-pack of tin-cube sensors. Bulky, but they do work well.

Early (10+ years ago) Sony tin-cube models were continuous signal compatible, but these probably are not.

I found this old thread where I tested these modules and confirmed the pinouts. Fifth post from the bottom. These babies are getting really hard to find now.

Back in stock. Grab 'em while you can, they are getting hard to find. Collector's item?

I think erco has found a new job with the Chinese government. May not pay much, but plenty of parts!

I succumbed...order placed.

Shye shye!
