BDsensor max operating temp

in PandaPi Mainboard

I was thinking about using the BDsensor in an enclosed printer that can reach up to 85-90 degree Celsius.

Is the BDsensor rated to handle such a temperature?

Thanks for the help!

Greets,

85 degree Celsius is the max working temperature for BDsensor, because of the chips inside the sensor.😀

Could you please check if there is a 'military certified' version (125degC) of the chip, and could you if so PM me a link to the chip (Mouser/DigiKey)? (So i can replace the chip)

I have a printer with heated chamber that prints PC and PEEK if the chamber can reach 110-125.

Thanks for making this great sensor, i received it and cannot wait to try it! Ill recommend your great sensor as much as possible!

For anyone having this 'problem'; you can best just put a 'ry thermal cutoff fuse' of like 77degC or lower in between the power wires. It will break the circuit at that temp and then turns on again below, so it never is on when at a too high temp. PS. If you get one, get a few, as with a heated high temp printer you should protect all electronics with a fuse somewhere, so if stuff might go sideways you are safe a powered off printer:)

Ooh, I found you don't need a heated chamber anymore these days anyway :)

just google 'op printer nd3d' or check OP™ Printer – nd3d just have to buy an IR ring tube and get a positional SSR to PWM control it.
