I bought one from AD, Polarized Retroreflective and it works but its really hard to set and I think its for a different application type.
What I have is a cart that travels back and forth (about 80 inches total travel), I mounted a reflector on the cart and I need to know when that cart is less than 50 inches away from one end, looking at a digital signal.
This is the sensor I bought https://www.automationdirect.com/ad...flective_(ss_-z-_fa_-z-_fb_series)/farn-bp-0a
It has a pot and says that its adjustable but I dont think its for sensing distance, I think its for breaking the beam/reflector
I think I need a 'diffuse' type but the distance is only up to 300mm and I need approx 1250, this does not have to be precise, with in 1-2 inches is fine
Anyone know what I need and it can be IFM, Banner, whomever just nothing fancy (expensive)
