Non-traditional housings styles are exemplified on the Bi20R-Q14-LU ring style and the Wi70-M18-LIU5 probe style sensors. These analog sensors are specified with a repeatability of less than 0.5 percent and linearity of 3 percent. The Bi20R-Q14-LU is a three-wire, 15 to 30V dc sensor with a 0 to 10V output in a ring style housing with a 20-mm diameter hole. This sensor is fit for the identification and sorting of small parts (such as screws) as the sensor generates a different output signal for each size part. Position control applications can be resolved with the Bi20R-Q14-LU by means of a cone-shaped target as well as the detection or measurement of tools (such as drill bits). The Wi70-M18-LIU5 is a four-wire, 15 to 30V dc analog sensor with either a 0 to 10V or 4 to 20 mA output. Housed in a standard 18-mm barrel, the 75-mm probe has a linear operating distance of 70 mm. This probe style sensor can detect all metals and can be used in a variety of areas, such as the positioning of metal parts as they move over the length of the probe. TURCK http://rbi.ims.ca/4912-550
