Reliable Proximity sensors

Post by Jrlee »

Where can I get some reliable proximity sensors? I have been replacing too many of the eBay sensors. My router is setup for auto squaring with the sensors in series. NPN-closed Thank you for all replies.

The sensors I bought from Automation Direct work good. Lot's of options to fit your mounting and sensing distances.

I'd like to know why you are replacing them?
Proximity sensors are known to be very accurate. There are different types though: Capacitance, Inductive, and Magnetic among others and they work best in different applications.
How are you mounting them? The correct way is for the trigger to move across the end of the sensor at a 90 degree angle, not directly into it.

GBCues is correct, the flag or "target" needs to pass across the sensor's face, not come up TO its face.
Automationdirect.com did a good video on putting NC Prox sensors in series. It was posted on this forum.

kentonsj thank you< I am looking at theirs. I have bought a few things from them. How long have your sensors ran?
GBcues they are inductive. They are positioned so that they are actuated by the metal coming towards them rather than past them. I am confident that they were not banged. Is there any difference in accuracy in either way?

I agree with others, I bought the ROKO one Keith posted but on eBay and they have not had any issues in over a year. I have these on two machines and they work everytime. I also have them mounted so the flag pases BY the sensor and not directly at it.

Thank you for all of the replies. Sorry I didn't update sooner but I have ordered 4 new sensors from Automation Direct and will change the way they are sensed as per the previous posts.
