8 Copyright © 2005 Rockwell Automation, Inc. All rights reserved. Application Examples Contrast Detection In this application: Sensor detects the dark mark on a light background

Installation Notes Teach Instructions –Point laser at Light Condition Diffuse – point at target Retroreflective – point at reflector Contrast – point at lighter color (e.g. white background when detecting black mark) –Push and hold Teach button for approximately 2 seconds until yellow LED turns on –The unit is taught (one push Teach!) –Point the laser at the other condition and check that the LED turns off –If the yellow LED is flashing, the sensor output is on but the sensor is in a low margin state (the light is less than 2X gain) –A “Fine Teach” operation is available. The process is the same except that instead of holding the Teach button for 2 seconds you hold the button approximately 8 seconds until the LED begins blinking. This mode is not generally recommended because the excess gain is very low.

Installation Notes Microcube Reflector –It is recommended that the Polarized Retroreflective Laser is used only with a Microcube reflector, such as the –Standard reflectors have much more variability and may not provide reliable detection. Important Note on Mirror Response in Polarized Retroreflective models –Lasers are highly collimated; therefore, the polarizing filters are less effective than on standard infrared sensors. As a result, Mirror Response is possible. Mirror Response is when the sensor sees a mirror or shiny surface and “thinks” it is the reflector, which means the object will not be consistently and reliably detected. –The LaserSight 42CM will not have mirror response on applications of less than 10m sensing distance if the unit is properly set up. Teach the sensor with a reflector at a distance of 10m or less to guarantee no mirror response at any distance. If the sensor is taught with a reflector at more than 10m, the device may experience mirror response. This allows the sensor to be used in longer range applications (up to 30m) if mirror response is not a concern Microcube Reflector

AEL < 0.39mW 2 Visible lasers (400…700nm) where blink reflex provides eye protection. May present some potential for hazard if viewed directly for extended periods of time. AEL < 1mW 3a Lasers that normally would not produce a hazard if viewed for only momentary periods with the unaided eye. They may present a hazard if viewed using collecting optics. AEL < 5mW 3b Lasers or laser systems that can produce a hazard if viewed directly. This includes specular reflections.
