M30 Capacitive Proximity Sensor Switch Non-Shield Type LJC30A3-H-Z/BX Detection 1-15mm 10-30VDC 200mA NPN Normally Open(NO) 3 Wires

Incredible sensor. Better than most

Received item in good condition - fast shippingThese M30 proximity sensor performed very well in my test,Operated well in the voltage range I tested it for - 10vdc - 15vdcHad no problem short term current of 150ma and longer term 50ma, at 10.2vdc,Worked perfectly, did not even need to adjust sensor gain, maybe something that should be checked,Picked up wood at about 3/4 inch the way it came set, I will be using it for sawdust, so will update review if any problems later,For now I would have to recommend product as an inexpensive alternative to much more expensive sensors like $100-300 Allen Bradly but never for industrial as reliability is to much a concern,Would also for longer life if it is an option to use it at the low end of voltage rating, excellent for the hobbyist or for a wood working sawdust silo,

This device works but unfortunately the detection distance is hardly 1mm. Virtually the object has to touch the sensor before it sends the trigger. This is useless if you want a reasonably finite detection distance (say at least 5mm) before the sensor triggers.

Good proximity sensor for general positioning.
