Color Sensors We Know Until Now, Our History with Color Sensing Technology has Been Limited to a Class of Sensors Known as “Color Mark” Sensors Our Offerings Include: Visible LED Convergent Sensors Visible LED Fiber Optic Sensors R55 Series Contrast/Registration Sensors

Are Contrast Detectors Registration Sensors……... Not SLOW Color Analyzers

Introducing QC50 Color Sensors True Color Analyzer

QC50 Series Features z Analyzes and Compares –Color to Color or –Varying Intensities of One Color z Programming Options for 1, 2, or 3 Colors z 3 Programming Parameters –Channel –Sensing Mode –Operating Status

QC50 Series Features z Four LEDs plus 4-Digit Display –Shows Configuration & Operating Status z Three Outputs per Sensor –One Output for Each Channel z Built-In OFF-Delay Options z Ten Tolerance Levels z Built-In GATE Feature z Non-Volatile Memory for Data Retention Output LED 3 Output Channel LEDs Set Push Button Select Push Button 4-Digit Display

QC50 Series Specifications z 10-30V dc z Three Outputs per Sensor –Select 3 NPN or 3 PNP by Model z OFF-Delay with Six Selectable Options –0, 5, 10, 20, 30 or 40 ms z Ten Tolerance Levels, 0-9 –0 is Most Selective, 9 is Least

QC50 Series Specifications z 335 µs Response Time z 20 mm Typical Sensing Range z Two Push Buttons (set & select) for Programming z 4-Digit LCD Display –Sensing Mode, Diagnostics, Tolerance Level, Channel Status z Four Indicator LEDs –Yellow – Power –Three Green – One for Each Channel Output

QC50 Series Specifications z Sensing Modes: –Color (indicated with a “C” on display) yOnly Colors are Sensed, Useful for Sorting Up to Three Distinct Colors ie: red/green/black –Color & Intensity (indicated with a “C_I” on display) yA Gray Scale is Included in the Sensing, Useful When “Batch” Sorting or Sorting Within a Single Color Family ie: light blue/medium blue/dark blue

QC50 Series Specifications z Tolerance Levels: –A Setting of “0” Indicates the Ability to Accurately Detect a Very Small Change in Color yIdeal for Color Accuracy on Fine Print Projects –A Setting of “9” Indicates the Sensor Will Accept a Wider Range of Target Conditions yIdeal for Accepting a Somewhat Variable Range of Molded Plastics

QC50 Display

QC50 Series Set-Up Step 1 z Position New Color Target, Press & Hold “SET” >2 sec. (channel 1 selected by default) –Output LED: OFF –Channel LEDs: All OFF –Display: “SET1”

QC50 Series Set-Up Step 2 z Click “SEL” Repeatedly Until Desired Channel is Displayed –Output LED: OFF –Channel LEDs: All OFF –Display: “SET1”, “SET2” or “SET3” z When Desired Channel is Displayed Click “SET”

QC50 Series Set-Up Step 3 z Click “SEL” to Choose Color or Color & Intensity –Output LED: OFF –Channel LED’s: All OFF –Display: “C” for Color –Display: “C_I” for Color & Intensity z Click “SET” –Sensor will Save Color Settings

QC50 Series Set-Up Step 3 (con’t) –Output LED: ON –Channel LEDs: Selected Channel ON –Display: “uPdt” (flashing for 2 seconds)

QC50 Series Set-Up Step 4 z Set Tolerance Level –Click “SEL” as Many Times as Necessary to Reach Required Tolerance Level –LCD Display: “toL0”, “toL1”, … “toL9” z Click “SET” –Sensor Saves Tolerance Level

QC50 Series Gating Function z Sensor Contains Passive Gate –Red Wire Floating or Tied Low Allows Normal Sensor Output –Red Wire Tied High Inhibits Outputs From Conducting

QC50 Applications Color + Intensity Sorting Color Sorting Color Mark Detection

QC50 Series Target Industries z Packaging z Error Proofing z Pharmaceutical z Semiconductor z Material Handling z Printing z Web Handling z Plastic Molding
