This thermister is also used on elego Centuri carbon. What about the connector?

This does not have the connector for the wire! I dont have the pins or the crimper. Can this wire be found and have the ends crimped on? 3D-001 OSEPP Electronics LTD | Prototyping, Fabrication Products | DigiKey Marketplace

I think this is the failure part. The Soldi state transister starts to warm up, but it shuts off after three min. the heat sink it is mounted on get only a little warm, not like heat sinks where they were pretty toasty. I dont have my digital multi meter “Trying to find it” to test it so will just order it..but need the connected end??? Thanks for anyone who can reply!!

Hello, Mechatronicsman. Welcome to TechForum!

Do you know which connector you’re looking to use on this device? Are you looking for a DMM thermistor test probe, rather than a solderable device like 2234-3D-001-ND?

let me measure it

Can you provide clear images of the connector housing from a few different angles, without the caliper in the way?

As well, are you able to provide a pitch measurement? Pitch is the most critical measurement to get right. Additional information on making a pitch measurement can be found here: Pitch of a Connector.

On the mither board? Try cell phon is pain when it tries to focus. Will send your way

Images of the connector on the cable are fine. Apologies, the calipers obscure details of the housing you want me to identify and make doing so difficult. There are a very large number of different options even when pared down as far as I can from available information: See options list here, for example: Rectangular Connector Housings

Do you want a close up of the connector??? The front and side types? I dont think the manufacture are going to give away those details.

The Elegoo Centauri Carbon 3D printer uses an NTC 100K thermistor (likely with a beta value of 3950) for both the hotend/nozzle and heated bed temperature sensing. This type is standard in Elegoo’s high-performance printers like the Neptune series and is compatible with the Centauri Carbon’s hotend design.

Key Ratings and Specifications:- Temperature Range: Rated for continuous operation up to 300°C (suitable for the hotend’s max of 320°C, though prolonged exposure beyond 300°C may reduce lifespan).

  • Resistance at 25°C: 100 kΩ.
  • Connector: PH2.0 (standard for Elegoo hotends).
  • Physical Size: Typically 3 mm diameter x 10 mm length cartridge, with ~100 mm total cable length.

The bed thermistor operates at much lower temperatures (up to the bed’s max of 110°C), so it’s well within the rating. For the chamber (if equipped or modded), a similar NTC is used but rated for ambient to ~60°C monitoring.

These specs ensure accurate feedback for printing carbon fiber and other high-temp/abrasive filaments. Replacement parts are available directly from Elegoo or third-party sellers. If you need replacement instructions, check the Elegoo Wiki for hotend/bed assembly guides.

Hi @mechatronicsman ,

Try this:

Does this come out of china? I cant wait 16 weeks. I could buy via ebay or some other source. BTW does these sockets require a crimp plier to crimp onto the wires then inserted into the connector?

Hi @mechatronicsman ,

No, these are genuine Japanese JST parts. You’ll get them from DigiKey in a day or two, depending on your location (do not forget to order the contacts too). Yes, you’ll need a crimping tool. Usually the official tools are expensive, as they are for industrial use, but for a few crimp cycles, a hobbyist grade will do.

I have used Iwiss tools with a great success.

Cheers, heke

That company that sells this tool shows I need to order 20 of these crimp tools.

If I has a power supply, and used a probe to power the mosfet and it did not shut down, I would then suspect the thermister is limiting / not limiting the voltage/current to the circuit board sensor.

I came across this on google ai.

Hello mechatronicsman,

As another solution, we do have the pre-crimped leads linked HERE that would work with PHR-2.

The leads have this thermistor on the end? elegoo is not releasing its images of the parts “unless I ask” online. What I like to also do, create a separate warning system the parts are about to fail. The 3d printer does not have that type of tech where it constantly monitors the restance / voltage or current.
