1756-OW16I罗克韦尔AB系列PLC模块

按检测方式可分为漫射式、对射式、镜面反射式、槽式光电开关和.光纤式光电开关开关量输出模块1756-OW16l

1、对射型由发射器和接收器组成，结构上是两者相互分离的，在光束被中断的情况下会产生一个开关信号变化，典型的方式是位于同一轴线上的光电开关可以相互分开达50米。

特征:辨别不透明的反光物体;有效距离大，因为光束跨越感应距离的时间仅一次;不易受干扰，可以可靠合适的使用在野外或者有灰尘的环境中;装置的消耗高，两个单元都必须敷设电缆。

2、漫反射型是当开关发射光束时，目标产生漫反射，发射器和接收器构成单个的标准部件，当有足够的组合光返回接收器时，开关状态发生变化，作用距离的典型值一直到3米。特征:有效作用距离是由目标的反射能力决定，由目标表面性质和和颜色决定;较小的装配开支，当开关由单个元件组成时，通常是可以达到粗定位;采用背景功能调节测量距离;对目标上的灰尘敏感和对目标变化了的反射性能敏感。

According to the detection method, it can be divided into diffuse type, reflector type, mirror reflection type, trough type photoelectric switch and. Optical fiber type photoelectric switch switch output module 1756-OW16l

1, the beam is composed of a transmitter and a receiver, the structure is separated from each other, in the case of the beam is interrupted will produce a switching signal change, the typical way is located on the same axis of the photoelectric switch can be separated from each other up to 50 meters.

Features: Identify opaque reflective objects; The effective distance is large, because the beam crosses the induced distance only once; It is not easy to be disturbed, and can be used reliably and appropriately in the field or in a dusty environment; The consumption of the device is high, and cables must be laid in both units.

2, the diffuse reflection type is when the switch emits a beam, the target produces a diffuse reflection, the transmitter and the receiver constitute a single standard part, when there is enough combined light back to the receiver, the switch state changes, the typical value of the action distance up to 3 meters. Features: The effective range is determined by the reflection ability of the target, by the surface properties and colors of the target; Small assembly costs, when the switch is composed of a single component, it is usually possible to achieve coarse positioning; Using the background function to adjust the measuring distance; Sensitive to dust on the target and to the changing reflection properties of the target.
