Important Info Overview These sensors have scratch-resistant optics and the emitted light can be switched off. They use the transit time measurement principle to measure the distance between the sensor and the object. Wenglor interference-free technology (wintec) has revolutionized sensor technology: It makes it possible to mount several sensors directly next to, or opposite each other without the sensors influencing each other. The sensors reach a very high switching frequency and use laser class 1, which is safe for the human eye. Features Secure detection of black objects also in extremely inclined positions with wintec No mutual interference with wintec Interference-free towards gloss in the background with wintec Reliable in case of glossy objects with wintec 2 mutually independent switching outputs
