YXQ12x150mm Cylinder 110V Cartridge Heater with String for 3D Printer Build Plate 500W 2 Pcs

Your basic heat cartridge used to heat an aluminum 6x6x1.25 plate to ~200°F. That took 15 mins or so. Worked well with thermo paste. The only problem was the shipping took about a month which I did not realize. Had to order from another site, which I received in 3 days, to accomplish my task.If you need the cartridge for your build soon, look elsewhere. It shipped from China on a row boat.

The overall quality looks very good. The fiberglass insulated wire stripped more easily than other similar high temperature wire I've used. I measured the cold resistance of eight cartridge heaters and they were all between 37.5 and 38.1 ohms. The only issue so far is the red insulation sleeves at the rear of the cartridge heater. Because this is a high temperature application, this isn't heat shrink tubing. It looks like silicone tubing, and they're a fairly loose fit over the crimped connections where the wires attach to the heating element. (see image) Make certain that the insulation cannot slide down in your application. It would be very bad to short 120 VAC at the heater, or possibly energize the metal chassis of a piece of equipment with a faulty ground connection. Some red silicone high temperature sealant might be able to secure the insulation sleeves. I used a couple of small wire ties to secure the sleeves in my application, as the wires are exposed to free circulating air and won't be very hot.

I'm using them in a rosin press and they work great. With large plates 5X7 and 1.5" thick plates. heats to stable temp in 5 minutes. Happy happy joy joy

I ordered these as part of a project for demonstrating temperature control systems. These work fine for the intended application, which only uses about half the specified wattage.

Still in use months later. Maybe once a week I use them in my rosin press.

Worked very well for my wood-bending operation.

These are quality and I have not had any problems out of the four I purchasedI don't like the red sheathing where the wire connects to the cartridges, but you can easily use your own heat shrink or wrap

Great price
