SICK Background Suppression Photoelectric Sensor, Rectangular Sensor, 100 → 2500 mm Detection Range

Very high strength and long life for heavy industrial use characterize the W24-2 product family in a metal housing. The "optical" robustness is guaranteed by a high insensitivity to stray light and by large functional reserves. The high degree of protection IP69K complements the mechanical robustness, even in a humid industrial environment. These sensors can thus be used with the standard or powerful front window heater, such as a rear window heater in a car, even outdoors with protective boxes. The various diagnostic functions make it possible to maintain the availability of the installation and to detect any operational interruptions in advance. The sensors are equipped with a minimum of different functions in order to reduce the diversity of the devices and, thus, their storage. In addition, both DC and DC / AC devices are offered in this form.

Robust die-cast zinc housing with protection class IP69K
Control elements protected by a cover
High insensitivity to stray light from photoelectric detectors
Switchable: PNP / NPN and light / dark
DC or DC / AC version with UL approval
Optional: test input, time scales, contamination message on the alarm output, front window heating, even in powerful models
M12 connector or M16 screw connection: rotatable by 90 °

Very high resistance and long service life thanks to the metal housing and the IP69K degree of protection
Very high "optical" robustness in the event of parasitic light and mounting devices facing each other
High availability thanks to the very large functional reserve for reflex and single-beam barriers.
Prevents or reduces the formation of condensation water on the front window during temperature variations thanks to standard or powerful front window heating
Mounting compatibility due to identical shape of DC and DC / AC devices

Positioning of the reels before and after the winder
Product detection on processing machines and moving beds during post-production logistics
Correct alignment of materials on conveyors during post-production logistics
