Happisland 5pcs NTC 3950 100K Thermistor with 1 Meter Wiring and Female Pin Head for RepRap 3D Printer Heatbed or Hot End

Two very minor ISSUES with this product FOR EVERYONE:1) This does not have the standard black .100 header connector as advertised, it has White JST XH2 connectors. This was a pleasant surprise for me, but it may be an unpleasant surprise for others.2) As another reviewer mentioned, there is a small gap, about 1mm which is completely un-insulated where the leads meet the thermistor, I added kapton tape.For those using MARLIN FIRMWARE, this works perfectly with setting number 11I have an E3D Titan Aero with the V6 block; it was designed to use a E3D cartridge, but my leads had broken off so I bought this product. I stuck it in the hole where the cartridge went, tightened the grubscrew to clamp it down, and it worked great. Saved loads of money over a new cartridge.

Mine came with the black .1" header connectors, not the white connectors that my MP select mini uses. I cut the wires about 1-1/2" from thermistor and soldered them into th old wires. much faster than replacing the whole wire as shown in a youtube video. If you're not skilled with a soldering iron and have small diameter heat shrink tubing replace the whole item.Thanks to Amazon having these in stock and two day prepaid (prime) shipping my printer was only own for four days.

New to 3D printing, I managed to break the cable on my Prusa i3 MK3 heatbed thermistor. Part from the manufacturer was only $4 but $21 shipping. This had the same specs for a much more reasonable price. I've replaced my heatbed thermistor with this one and the printer is back to printing.My only issue is nothing to do with the manufacture of the piece itself. Just that the cable is longer than the original part. I have added a few extra coils along the power cable from the heatbed to the processor board. Wrapped the extra loop in plastic spiral wrap.

Actually I thought they were stud type thermistors and they were not. That is why they did not receive 5 stars. My fault. I was able to drill the old thermistor out of its original stud and insert this thermistor into it and crimp the stud to hold. Then it fit and functioned perfectly fine in my Robo3d R1+

Good product. Nothing to complain about.I ordered to install on a 3D printer. But the 3D printer had the thermistor inside a little cartridge but I have not found the cartridge assembly. But managed to solve the issue. And this one only have a temperature difference to other temperature sensors about .3°C.My main concern when I bought was to have a huge temperature difference or poor build quality. But surprisingly it is well built specially because I paid 9U$ for 5 and others online was close to 10 each!

My Prusa's bed sensor went on the fritz and started throwing "MINTEMP BED" errors. This patched it right up. The pre-installed connector fit the socket on the Prusa's driver board. Only issue, and a minor one, is that the wire is too long and needed to be bundled up.The manufacturer certainly didn't use matched-metal thermocouple wire and hardware, but at the printer's temperature ranges, it doesn't matter.

Apparently the Prusa Mk3s have a habit of breaking their bed thermistor wires from constant Y-axis movement of the bed. I was very worried about cutting apart my 3-ish month old printer to do the repair, but it turned out to be a quick fix. These thermistors work perfectly for the job, with lots of lead to cut and solder if you need to.

Wish the wires were not loose, but connected. Wish more protection near the sensor itself. But it reads the correct temperatures and a 5 pack is necessary because the first one died when I applied my set screw. But out of box all 5 work.
