MAIN MENU PRODUCS APPLICAIS INDEX SELECI GUIDE Luster Recognition Sensor PI-G Series Features Detection unaffected by target color Luster differentiation capability 1-ms response speed Built-in hysteresis adjustment trimmer Detecting Distance 10 to 25 mm (0.39" to 0.98") Description Unique principle of operation Utilizing our unique optical system, PI-G sensors can provide on-line luster differentiation. Stable detection unaffected by changes in target color he PI-G Series detects a change in luster only. herefore, detection is unaffected by changes in target colors on printed mark, etc. Visible beam spot simplifies sensor adjustment Since the PI-G Series employs a visible red LED as the light source, the point of detection can be visually confirmed. his allows the sensor head to be easily aligned with a target. Hysteresis adjusting trimmer Hysteresis can be adjusted based on target surface conditions (wrinkle, etc.), oscillation or slant. -delay/-delay timer function Operating principle When light hits a surface, the amount of reflection depends on the shinyness of the surface. When the luster level is high (lustrous), the light reflects specularly. When the luster level is low (lusterless), the light reflects diffusely. By detecting this difference with a line sensor in the receiver, luster can be differentiated. High Luster level Low Sensor head Reflection status of emitted light spot Line sensor in receiver Received light output Line sensor Light source 160 Artisan echnology Group - Quality Instrumentation...

MAIN MENU PRODUCS APPLICAIS INDEX SELECI GUIDE Hints on Correct Use Luster Recognition Sensor PI-G Mounting sensor head Mount the sensor head, with the supplied bracket, to suit the installation site. Mounting 2 or more sensor heads in close proximity will not cause interference. When detecting traveling targets, mount the sensor head as shown right. (Pay special attention to the orientation of the sensor head and direction of the target.) Correct Incorrect KEYENCE PS-001 KEYENCE PS-001 If ambient light enters directly through the emitter/ receiver face, the PI-G may malfunction. Always mount the sensor head with this side down. When mounting the sensor head, tighten the screws with a torque of 0.5 N m or less. Wiring Do not extend the cable more than 100 m 328.1'. he sensor head cable can be extended up to 5 m 16.4'. When not using synchronous input, cut the synchronous input wire at the base. he PI-G Series requires a startup time of about 300 ms before being ready to begin operation.
