Fundamental application problem: Inductive prox sensor is latching on (or…failing to turn on)
- The prox sensor gap is set to turn on when the target approaches, but it does not turn off when the target recedes (latching on)
- The prox gap is opened up until sensor turns off at maximum target approach, but it fails to detect the target upon the next approach cycle
- The prox sensor gap is set to turn on when the target approaches, but later on the operation becomes intermittent (prox fails to reliably detect the target)
Solution: High-performance miniature inductive prox sensor
Critical sensing performance specifications:
o Low variation of switch point from sample to sample
o Tight repeat accuracy of switch point
o Low temperature drift of switch point
o Low maximum hysteresis (distance between switch-on to switch-off)
