Vision sensor promises photoelectric ease
The Inspector's rugged IP67-protected metal housing ensures it can withstand harsh industrial and production line environments, for quality assurance inspection in any location or orientation.
Incremental encoders provide smooth running
Bearings are separated as widely as possible within the encoder body, to achieve smooth and vibration-free running.
All the devices are equipped with laser diodes that emit a visible spot of light, simplifying alignment of the sensor, even to tiny targets.
A pair of LEDs advises the user of the status of the sensor output and the laser during commissioning and operation.
Scanning frequencies range from 200 to 1000 times per second, and the rapid response of all W190 sensors makes them ideal for high-speed applications.
Housed in industry-standard ABS plastic housings measuring only 44 x 15 x 30mm and sealed to IP67, they are suitable for use in harsh environments.
They are available with a rotating M8 connector or a 2m cable.
For less demanding applications, Sick offers the Standard Series of economical models with basic functions.
The series includes three versions: A proximity switch with background suppression in 40-100 or 100-300mm scanning ranges; a reflex switch; and a through-beam photoelectric switch with a separate receiver.
All standard models have a light/dark selector switch, and sensitivity is set with potentiometers.
Typical applications for the standard series are in distribution, packaging, assembly and metalworking.
For more demanding applications, there is the High Grade Series, which includes two variants: A proximity switch with background or foreground suppression in 40-100 or 100-270mm scanning ranges; and a reflex switch suitable for detecting transparent objects.
Reflex switches are available to detect foil or film, or more difficult targets, such as thin-walled bottles.
High Grade models are programmed through their menu-driven liquid crystal displays, and a simple touch of a button starts the "teach-in" mode, which adjusts range and scanning distance automatically.
Time delays up to 10s can be programmed, and a lock function prevents tampering with the sensor's settings.
W190 High Grade sensors will find applications in the pharmaceuticals, electronics and semiconductor industries; and in packaging and bottling plants.
