What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).
Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...
The FB series M18 plastic DC photoelectric sensors are 18mm sensors in diffuse, polarized reflective and through-beam models with sensing distances ranging from 70mm to eight meters. All models ...
