Light curtains for measuring tasks operate according to the barrier principle, so the transmitter and receiver are integrated in separate housings. The switch output switches and an analog output reads out corresponding voltage or current depending on how many and which light beams are interrupted. The function of the transmitter can be tested using a test input.
Light curtains for measuring tasks can be adjusted intuitively and easily via the menu-driven graphic display. A bar graph makes intermittent rays visible, making alignment, commissioning and troubleshooting much easier.
Application examples:
- Detection and measurement of objects
- Web edge control
- Protrusion control
- Sag control
- Height control
