These miniature sensors determine distance between the sensor and the object by means of transit time measurement. wenglor's interference-free technology (WinTec) is revolutionizing sensor technology: it prevents numerous sensors arranged directly opposite or next to each other from interfering with one another. The sensors reach a very high switching frequency and use laser class 1, which is safe for the human eye. Range: 0...1000 mm. Speed: 1000 Hz. Output: PNP. Circuit: NC+NO. Housing: 32 × 22 × 12 mm (1K)
