The Leuze Sensor GS63B/66.3-S8 (GS 63B/66.3-S8, GS63B663S8) part number 50143910, is from the 63 series detects non-transparent labels with a minimum width and gap of 2 mm each.

It uses LED infrared light sources with a 940 nm wavelength for reliable detection. The sensor has a digital switching output and operates on a 10 to 30 V DC supply voltage range.

Equipped with a transistor push-pull switching element, it generates signals in the label gap or directly on the label with a fast response time of 0.05 ms. Its fork design and 3 mm mouth width allow easy integration into conveyor systems. The sensor’s metal and plastic housing ensure durability in temperatures ranging from -20 to 60 °C.

With operational controls including a teach button, it offers convenient setup. The sensor’s compact dimensions of 11 mm x 30 mm x 80 mm and lightweight of 55 g make it easy to handle and install. Its housing, made of diecast zinc and chemically nickel-plated metal, guarantees resilience even in challenging environments.
