Pencil-Type Contact Sensors Measuring 8 mm in Diameter

Enclosed in a cylinder measuring barely 8 mm in diameter, the novel head of the pencil-type GT2 Series sensor by Keyence enables absolute measurements with an accuracy of 1 µm. Ease of installation makes the sensor good for all types of industrial inspection applications. The contact sensor has been considerably slimmed down to the size of a pencil. Enclosed in a cylinder measuring barely 8 mm in diameter, the product now fits in tight inspection spaces.

The Scale Shot System II, the second generation of Keyence's proprietary measurement system, uses a receiver, a transmitter and a high-performance processor to allow the sensor to make high-accuracy absolute measurements. This technology uses a high-resolution CMOS sensor that rapidly scans the glass scale encased in the sensor head's slim body. This world-first detection technology reads patterns engraved on the scale to make absolute position measurements while overcoming the disadvantages of conventional methods.
