光幕传感器是一种快速响应和多功能的光传感器。它是通过将光线传入传感器的传感工作面板上，检测光线强度来工作的。当光照射进入传感器的感应区域时，它就可以立刻发出信号，从而实现探测，计数和测速等功能。
Lighting curtain sensors are fast response and multi-functional optical sensors. It works by introducing light into the sensing working panel on the sensor and detecting the intensity of the light. When light irradiates into the sensing area of the sensor, it can immediately give out the signal, so as to realize detection, counting and speed measurement, etc.
光幕传感器由被照射物体，发射头和敏感探头组成，发射头通常由LED灯组成，而敏感探头则是来接收光线的。当光照射进入发射头时，产生的光线将被敏感探头接收，在探头的内部，光线将经过传感器的神经元细胞，最终转换成电元能，触发接近发射头的传感器发出信号，从而实现功能。
The light shielding sensor is composed of the illuminated object, the transmitting head and the sensitive probe. The transmitting head is usually composed of LED lamps, and the sensitive probe is used to receive the light. When light is irradiated into the transmitting head, the light generated will be received by the sensitive probe. Inside the probe, the light will pass through the neuron cells of the sensor and eventually be converted into electrical energy, triggering the sensor close to the transmitting head to send out the signal, so as to realize the function.
光幕传感器可用于自动叫料机械手、机械臂抓取和放置、计数器、及自动安全防护系统中。其实根据逻辑需求程序，在抓取或放置进程中，光幕传感器可用于识别物品形状、限位定位、停止定位、及压力反馈等功能，使机械手快速精确的抓取和放置物品，为工厂生产提供支持。
Lighting curtain sensors can be used in automatic material calling manipulators, mechanical arms grasping and placing, counters and automatic safety protection systems. In fact, according to the logical requirement program, in the process of grasping or placing, the light curtain sensor can be used to identify the shape of the articles, limit positioning, stop positioning and pressure feedback, so that the manipulator can grasp and place the articles quickly and accurately, providing support for factory production.
总而言之，光幕传感器是一款多功能的传感器，它有着快速响应、低成本、低功耗、准确精确的特点，可用于机械臂抓取和放置、计数器、及自动安全防护系统中，改善工厂生产水平，为现代工厂提升效率。
In a word, the light shielding sensor is a multi-functional sensor with fast response, low cost, low power consumption and accurate precision. It can be used in mechanical arm grasping and placement, counters and automatic safety protection system, improving the factory production level and enhancing the efficiency of modern factories.
