IR Infrared Emitter Extension Cable 1.5m Long 45 Degree Emission Angle 3.5mm Jack Single Red Head 5pcs

I do a lot of automated IR control work and this is a very cost effective item. Even though it's not the highest of quality as I've had a few issues with the plastic cover falling off after dropping it, (my fault) it's priced right and I will be buying more of these. I am very pleased with this purchase.

Good length. Easy to install.

Emitters seem to work well positioned a centimeter or so above, below, or beside the equipment IR receiver. I have one IR receiver in bright sun for parts of the day, and the emitter works fine in those conditions. I plugged these emitters into a DIY circuit attached to a Raspberry Pi 4 and control them with ir-ctl. While I appreciate the seller answering my question regarding a diode datasheet, I believe they are mistaken. These emitters absolutely include a diode (the 'D' in IR LED). Without a datasheet, I took a shot and used a 120 ohm current-limiting resistor with a 5V signal. Working well so far. Regarding adhesion, I wiped the emitter base and the mating surface with isopropyl alcohol before applying the adhesive pad. Seems good so far, will update if it fails. **UPDATE: the included adhesive pads are no good, fail within days. I'm using 3M's Scotch Mount Indoor Double Sided Mounting Tape instead.

The adhesive tape seems a little foamy, so the emitter pulls away from the surface it’s mounted to slightly, which is purely a cosmetic gripe. These don’t have an led indicating to the eye that they’re transmitting but they’ve worked great with my control4 controller

The product did not work when plugged in, I assume it is cross wired because the sensor was hot to the touch within 5 seconds. I think this product is dangerous and would fear for having an electrical fire. I returned the product immediately.

Functions as expected

I needed a replacement emitter cable for my AV receiver, and the first one I tried out of the pack worked perfectly. I haven't needed to test the other four yet.

The length and everything else about these are perfect!

They work fine. I was surprised to find very little information inside the box about the pinout and current limiting resistor requirements. I had some 110R resistors from another project which seem to be giving these LEDs enough oomf with a 5V supply. A great solution if you’re building your own IR remote with an ESP32/8266. Stuck them to the inside of a HiFi rack and they’re happily blinking away.
