THE comprehensive W2 family of sensors from Sick opens up new automation opportunities. W2 class sensors can be used wherever space is tight.
Completely new application possibilities are now available - without external amplifiers - thanks to the interaction of a laser-like light source with an integrated optical Ics specially developed for Sick AG.
For the first time, miniature proximity switches with precise background suppression have been introduced onto the market. Photoelectric reflex switches and through-beam sensors with long ranges round off the W2 family.
Industrial standards and demands are met in their entirety: with metal-strengthened drilled holes for M3 screws (for mounting), M8 cable plugs, short-circuit protection, IP67, and above-average EMC, the sensors are robust and suitable for industrial use.
The photoelectric proximity switches are suited for use in tight, compact areas, such as those found in placement, pharmanalysis and handling machines.
The laser-like light spot allows precise detection of the smallest of parts on transport systems, in belt compartments and on robot arms. The scanner with background suppression is available with fixed ranges of 15 mm and 30mm.
Sick offers an energetic V-scanner for detection tasks of up to 50mm, and the newly developed pinpoint LED as a light source.
A highly homogenous input of current in the semi-conductor brings about a very high and even light intensity, without there being any detectable bonding wire and marginal light effects.
A precise laser-like light spot can thus be achieved - allowing appropriate detection tasks without the well-known disadvantages of real laser light sources, such as reduced lifetimes and troublesome laser protection classes.
