MARK•EYE® Pro
High-Resolution Registration Mark Sensor

The MARK•EYE® PRO sensor is designed and optimized for detection of printed registration marks on a continuous web at high-speeds.

The MARK•EYE® PRO delivers high-resolution performance by utilizing the broadband characteristics of a white light LED for detecting the greatest variety of color combinations on any color background.

Setup could not be easier with the "One-Touch" AUTOSET. Simply put the background in view; and press the black button if the background is darker than the registration mark or press the white button if the background is lighter than the registration mark.

Features and Benefits:
•    See color combinations on any color background
•    High immunity to ambient light, including strobes and indirect sunlight
•    5-LED Contrast Indicator
•    "One-Touch" AUTOSET push-button setup
•    Lens and Fiberoptic light guide options

SUPPLY VOLTAGE:
10 to 30 VDC.
Polarity Protected.

CURRENT REQUIREMENTS: 
45 milliamps (exclusive of load).

OUTPUT TRANSISTORS:
(1) NPN and (1) PNP sensor output transistor.
Outputs can sink or source up to 150 milliamps (current limit).
Short circuit protected; protected from pulsing at power up.

RESPONSE TIME:
• MEP45WL - Light/Dark = 45 µs 
  Repeatability = 13 µs
• MEP - Light/Dark = 175 µs

LED LIGHT SOURCE:
White = broadband color spectrum.

LIGHT IMMUNITY:
Responds to sensor's pulse modulated light source ... immune to most ambient light and strobes, including indirect sunlight.

PUSH BUTTON CONTROL:
" One-Touch" AUTOSET Pushbutton setup. 
Tweak adjustments with "up" or "down" buttons.

10 ms
25 ms
50 ms 
 

HYSTERESIS:
Set for high resolution ... less than one bar on the Contrast Indicator.

DIAGNOSTIC INDICATORS:
5 LED Bar graph functions in one of two modes:
1. Contrast Indicator ... Displays scaled reading of sensor's response to contrasting light levels (light to dark).
2. Status Indicator ... displays status of 5 selectable options.
Red LED output indicator ... Illuminates when the sensor's output transistors are "ON".
Note; If Output LED flashes, a short circuit condition exist. 
Amber LED ... Illuminates when in the options select mode.
Yellow LED ... Illuminates when the lock feature is activated.
