White LED contrast sensor


EMX Industries says its CNTX contrast sensor is the highest resolution white LED contrast sensor on the market. The company says the sensor is able to reliably detect up to 50 gray-scale levels. In addition, the CNTX sensorís round spot allows it to be mounted in any orientation. The sensor comes with standard features, including a two-digit display that shows the values of a background and a mark to indicate available switching margin. The CNTX has the ability to lock the controls so the operator cannot change the settings and cause errors. The output is automatically configured to PNP or NPN upon power-up, aiding in setup. The light source intensity is variable so it can be adapted to the background.
