Allen-Bradley高速传感器AB42CB
Allen-Bradley高速传感器42CB传感器共享许多相同的作为42ca通用功能行，但提供额外的增强在电气、机械和光学方面。特点包括更快响应时间，光/暗操作模式，直角封装，双LED输出，灵敏度调节，以及增加传感范围。
Allen-Bradley高速传感器42CB传感是可用的覆盖典型应用的模式。红外光源提供传感器尺寸极好的范围。直流操作确保与测量和控制电路发现在今天的工厂自动化系统中。
目标检测的信令是通过要么NPN或PNP输出。这输出短路保护保护传感器不受影响损伤。光或暗操作条件是通过接线选择的，而不是型号。
Allen-Bradley高速传感器单轮调整包括在内。设置传感器的光学灵敏度。提供两个LED指示器。指示电源和输出状态传感器。作为一种替代18mm圆柱形封装，罗克韦尔自动化/Allen Bradley也提供的rightsight光电传感器。那个产品是直角设计的。节省许多空间
Allen-Bradley高速传感器42CB-P2LPA-M4Description：
Bulletin 42CB are high speed 18mm cylindrical sensors available in several sensing modes, with various detection ranges. The Fixed Focus Diffuse uses a visible red LED, all the other sensing modes use an infrared LED. These sensors are available with 10–30V DC, either PNP or NPN output and selectable light/dark operate mode on each sensor.
The sensitivity adjustment potentiometer and two LED indicators are mounted in the rear. The LED’s show the output is energized (yellow) and power is on (green).
Fast response time and the high switching frequency of all the Bulletin CB sensors (1kHz) allows for accurate detection of objects moving at high speed. The right angle orientation of this bulletin reduces the overall dimension of the sensor, and reduces the chance of accidental tearing.
