Reflex Sensors with Background Suppression
The sensor evaluates light reflected from an object. The output switches if the object passes within the selected range. These sensors work by the angular measurement principle. For this reason the color, shape and the surface quality of the object have almost no influence on the detection range. Even dark objects can be reliably recognized against bright backgrounds.
Applications
- Checking for presence of objects
- Recognition of minimal height differences
- Recognition of all types of objects, even in front of any type of background
- Recognition of all types of packaging
- Indication of fill-levels and stack heights
- Edge recognition Shelf-full messages for automated rack systems
Triple Beam Correction
Through the principles of electronic and electromechanical background suppression and the triple beam correction, it is possible to realize a highly accurate background suppression regardless to mechanical design.
Interface
Sensor functions can be activated and scanning results can be acquired via the RS-232 interface.
Adjustments
Adjustments are performed with a potentiometer. With Teach-In variants, adjustments are made with the appropriate keys, externally or via the RS-232 interface.
CP25/CP70/OCP662/OCP242
These sensors are equipped with a high resolution CMOS line array and a DSP (digital signal processor). Two switching outputs are available and a switching point can be defined for each output. The sensors recognize whether objects are located outside or inside of the range encompassed by the first and second switching point. Due to the novel technology, a very high sensitivity for black characterizes the sensors. Even glossy objects can be reliably recognized against bright backgrounds, as well as at various degrees of deviation. The small switching hysteresis enables the detection of even the slightest differences.
Laser Class
Sensors with laser class 1 have the smallest laser capacity according to EN 60825-1 and make warning signs redundant. Due to their higher light capacity sensors with laser class 2 achieve better specifications.
