The MK cylinder switch with IO-Link is distinguished by two configurable hardware switching outputs and further features made possible thanks to digital data transmission. For example, the sensor can learn the target stroke time and compare it to the actual value with the help of the ‘Teach in application’ function. In addition, the data storage function makes it easy to replace and restart the sensor.
With a housing length of 30 millimetres, the sensor is perfectly suited for end position monitoring on short-stroke cylinders. Thanks to two configurable switch points, it can monitor two end positions. This saves time and costs thanks to less installation and wiring complexity. The cylinder sensor is also ideal for inline quality monitoring thanks to its two switch points and linear signal output. The magnet attached to the piston ensures that magnetic fields are already detected in front of the sensor housing. This results in a total detection range of 50 millimetres.
Thanks to the second configurable switch point, the cylinder sensor with IO-Link can monitor both end positions on short-stroke cylinders with a stroke of up to 50 mm.
The signals can be set as required according to the cylinder types used.
This sensor can perform highly accurate monitoring tasks on pneumatic cylinders. With the relevant properties such as a repeatability of 0.2 mm, a linearity error of < 5% and a resolution of 0.01 mm, the sensor easily solves quality assurance tasks.
Thanks to the second switch point, the IO-Link cylinder sensor is ideally suited for detecting workpieces and errors in the placement process.
Using the window function, incorrect loading of the machine can be detected and directly reported to a controller.
Machine performance can be optimally monitored, even over longer periods of time.
Thanks to the new ‘Teach in application’ function, the sensor can also assume diagnostic functions for the pneumatic cylinder. The sensor determines a reference runtime and can detect when and how much the current stroke times deviate from the ideal state based on a permanent target/actual comparison. If the application-specific tolerance set by the user is exceeded or not reached, a warning is issued.
Undesired downtimes are particularly relevant for production facilities with a high output rate of manufactured products. The failure of an insignificant pneumatic damper on a linear slide in an assembly production line has caused the system to stand still for a certain time.
The new sensor can monitor the stroke time on this linear slide or on any linear actuator with a magnet.
