Sick (UK) adds sensor for difficult substrates

The four models in the Sick W2S range are contained in a rugged IP67-rated housing that measures only 7.7 x 21.8 x 13.5mm. Sick said the slim housing allows convenient mounting within tight spaces demanded by compact machinery. The double-sealed 45-degree offset cable entry minimizes environmental ingress and reduces accidental damage during operation.

PinPoint LED ensures a high-visibility light spot at sensing ranges up to three meters, and can be adjusted on the unit by a three-turn potentiometer. It is complemented by a high sensitivity 128-pixel array detector. There is no range difference in black or white surface detection (B/W shift).

Phil Dyas, an industrial sensor specialist at Sick (UK), said: ‘The new W2S performance enables high speed conveying lines to deliver efficiency even with matte black materials. The Sick W2S gives manufacturers the opportunity to integrate modern photoelectric sensing power where it was difficult and expensive before.

‘The W2S will consistently detect matte black materials with as low as one percent reflectivity, unheard of in this size and price range. The sophisticated background suppression software ensures high reliability and consistency whether detecting jet black, brightly colored, matte, transparent or highly reflective objects.’
