Prox switch target
Prox switch target
(OP)
We use a prox switch to detect rotary motion by mounting targets on the shaft of machinery (industrial - dirty). The target is typically a sprocket (4-6"DIA). The teeth moving by the stationary prox create pulses & we do the logic in the PLC. Does anyone out there know of a pre-fab target that can be purchased (more to the specs listed in most prox application sheets- target surface area .5w"x.5d"x.5"h spaced 1")? A sprocket tooth comes to a point and does not leave much room for misalignment.

Does the the prox switch have to be mounted perpendicular to the shaft? We used the same application in equipment we designed and mounted the prox switch parallel to the shaft. We then used a round piece of sheet steel welded to a shaft collar. In the sheet steel are drilled holes that are detected by the prox switch. Depending on the size limitations you can vary the number and size of the holes.

the putputs are programmable. for example, if you need an output to fire a cylinder from 120-150 degress you can program any output to do so. The output is then used as an input to a PLC or embedded controller.

Redlion makes several gear sets to bolt on for this application. They are not the only supplier, but they do have several to chose from.
Good Luck!
