Fork light barriers / Frame light barriers
Operating principle of fork and frame light barriers
Fork and frame light barriers belong to the category of position sensors and operate to the same principle as through-beam sensors. That means that the photoelectric system detects the interruption of a light beam. The advantage of fork and frame light barriers as through-beam sensors is that transmitter and receiver are integrated in one housing thus making time-consuming adjustment unnecessary.
Typical applications of fork and frame light barriers are:
- Part detection in supply guides
- Contour verification of components
- Web edge control
- Edge detection
- Monitoring of batch height
- Parts detection on rolls
Order fork and frame light barriers online from Automation24
Automation24 offers you selected fork and frame light barriers at low prices. We are glad to offer you branded quality of fork light barriers at an average of 20 per cent and of frame light barriers at an average of 16 per cent below the list price.
Our portfolio of fork and frame light barriers includes fork openings or journal lengths from 10 to 120 mm, available as pnp or at option as pnp/npn-switching. Due to the high operating frequency and a precise light beam (red light or infrared light) of the photoelectric sensors, detection of smallest parts is possible. Sensitivity setting is made via potentiometer. The robust metal housing of the offered fork and frame light barriers is particularly distortion-resistant as compared to conventional plastic forks.
At Automation24 you find a large selection of fork and frame light barriers at very favourable prices. Select the sensor suitable for you application now!
