Optical sensors are used in industry, more precisely in factory automation, to detect objects and their characteristics using light as a medium. They are triggered, for example, when the light is interrupted or the intensity of the light has changed. They operate according to certain basic principles: diffuse sensors (with and without background suppression), retro-reflective sensors, colour sensors, distance sensors and fork light barriers.
The SOE4 is one of our high-precision fibre-optic units. It enables switching frequencies of up to 8000 Hz, ranges of up to 2000 mm and is available with LED display as well as switching and analogue output. Thanks to the different mounting options (H-rail mounting or with through-hole), our fibre-optic unit SOE4 is easy to fit wherever it is needed.
Colour sensors have a transmitter that emits a light beam, which is reflected back by the detected object and then evaluated by the receiver. Evaluation is possible for the colours red, green and blue. The Festo colour sensor SOEC-RT-Q50-PS-S-7L has a range of 12 mm ... 32 mm and can be used in ambient temperatures of -10 °C ... 55 °C.
SOEG 系列的光电传感器特别适合在较远的距离下使用。SOEG-RS/RT 具有反射式传感器和背景抑制功能，能够检测各种尺寸的金属和非导电物体。SOEG-E/S 是一种对射式传感器，可用于 20 m 以内的范围。这两种光学传感器的特点在于，外观为圆形，并且通过开放式电缆末端或插头进行电气连接。
Festo SOOF 叉式光栅属于单向光栅组别。这种类型的光学传感器的优点在于，它们非常可靠和高效，而且可以非常迅速地完成安装。叉式光栅 SOOF的外壳坚固耐用，具有极高的抗冲击和抗振动能力。SOOF 有塑料或金属两种款型可选，具体取决于哪种材料更适合您的应用。叉式光栅 SOOF 具有一个 3 针插头接口和实用的 LED 显示器。SOOF-M（金属款）带有 IO-Link，并且有不同的运行模式可选，非常灵活。
