THE new W18-3 series of photoelectric switches, available from SICK Australia , sets a new standard in accuracy and operating properties.
The WT 18-3 photoelectric proximity switch is the technological highlight of the series -- integration of the latest SICK chip technology offers the opportunity of reliably solving demanding tasks with a high level of sensor availability under variable ambient conditions.
The application experience gained from the forerunner families has been consistently implemented in powerful system technology throughout the W 18-3 series.
Thus, features such as further improved immunity to both ambient light and mutual interference are as standard for this device as its optimised housing with reinforced mounting holes, its reader-friendly all-round LED, and its easy-to-clean flat optics.
In addition to its mechanical strength, the device's resistance to both electromagnetic and passive sources of interference, as well as to local high-frequency mechanical vibrations, has also been increased.
The detection precision and adjustability (key words: smaller red-light spot) of the WS/WE 18-3 through-beam photoelectric switch and the WL 18-3 photoelectric reflex switch have been considerably improved.
The sensors of the W18-3 series offer versatile use within a temperature range of -40ºC to 60ºC.
The WT 18-3 photoelectric proximity switch is the first device of its kind with chip technology that has been specially developed for scanners.
This not only provides considerably more precise detection results - it also allows electronic setting of the scanning distance with more accurate background suppression.
Teach-in of scanning parameters can be carried out using the potentiometer or, as an option, via teach-in.
Regardless of the teach-in mode selected - chip technology and electronic adjustment now make definition of the work-points of all the scanners faster and more precise.
Thus raising machine availability and allowing greater productivity.
During development of the W 18-3, a great deal of attention was given to compatibility with predecessor series.
One-to-one mechanical and electrical integration allows simple upgrading to the new W 18-3 when replacing the "old" W 18-2.
