Hannover, Germany - Erwin Sick introduced miniature photoelectric switches with precise background suppression-a market first, the company claims, thanks to a new "laser-like" light source that makes use of a specially developed optical ASIC.

The tiny W2 subminiature class sensors bring new applications into the realm of possibility. The onboard light source makes external amplifiers unnecessary.

The secret is a device that engineers call a "pinpoint LED." A stabilised current into the light-emitting diode brings about a very high and even light intensity, which achieves a precise laser-like light spot. The use of LEDs eliminates the well-known disadvantages of laser light sources, such as reduced lifetimes and troublesome laser protection classes.

The laser-like light spot allows precise detection of the smallest 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 30 mm.

Photoelectric reflex switches and through-beam sensors with long ranges round off the W2 family.

As small as they are, the sensors are robust and suitable for industrial use with metal-strengthened drilled holes for M3 screws (for mounting), M8 cable plugs, short-circuit protection, IP67, and above-average EMC.
