Limit Switch selection
-
Hi, everyone i am Nandhakumar. we are making one machine. So, I am using the DUET machine control board, that specification is (DUET3 MAIN 6HC). So, I need EMF compatibility and IP65 limit switches.
Kindly suggest the limit switch to meet our requirement and also share the details.

@NANDHAKUMAR10 See https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_endstops
Duet has wide compatibility with switches. Generally, any passive switch will work, connecting between the input pin and GND. Note is that the endstop devices only need to sink 0.12mA. If you need an active switch, ideally choose one that is powered by 3.3V or 5V, though the inputs on the 6HC can cope with up to 30V.

@NANDHAKUMAR10 I like these
https://www.ia.omron.com/product/item/1017/
and have used then on several machines. You can get them with different sensor styles. They are very expensive new, but can be purchased from eBay, new and used for next to nothing. -
@3DPMicro Good to know! I've seen those Omron sensors pop up a few times but never tried them myself. Might check eBay like you said, sounds like a solid deal especially for prototyping..
