Digital Contact Sensor from Keyence
Keyence Corp. of America
November 28, 2007
The GT general-purpose contact sensor from Keyence Corp. of America, Woodcliff Lake, NJ, provides height and thickness measurement for production line and other high-speed applications. Measurements are performed in the compact GT amplifier, requiring no PLC or external data processing. The IP67-rated sensor incorporates a linear ball-bearing air-push spindle tip that pneumatically extends and retracts for each measurement cycle. A calibration pushbutton causes pneumatic spindle extension to the target surface, takes a zero point measurement, the spindle retracts, and calibration is complete. The amplifier performs all data handling and provides a go/no go output once calibrated. You can use up to 10 GT amplifiers and sensor heads; multiple amplifiers snag together with data pass through.
