R55F Series Fiber-Optic Color Mark Sensors For Plastic and Glass Fiber Optics Printed in USA 05/01 P/N 57945 rev. B R55F Series Sensor Features • Outstanding color contrast sensitivity; detects 16 levels of gray scale. • Depending on beam color, reliably detects the toughest color mark contrasts, including 20% yellow against white. • Fast, 50-microsecond response. • Choose from infrared or one of four visible beam colors: red, blue, green and white. • Fibers mount in small and otherwise inaccessible areas. • Easy push-button programming options include Static TEACH, Static Single-Point TEACH, Dynamic TEACH and Remote TEACH; plus manual sensitivity adjustment. • Non-volatile memory. • Glass fiber models function well in harsh environments typically associated with printing processes. • Plastic fiber models function well in applications that require repeated flexing of the fibers. • Fibers install quickly without tools. • Bipolar (NPN/PNP) outputs with three Delay settings (0, 20 or 40 milliseconds). • Choice of integral cable or QD connector models. • Mounts flat or to 35 mm DIN rail; two brackets included with sensor (one for angle mount, one for flat mount). R55F Series Sensor Overview The R55F Fiber-Optic Sensor was developed to provide simplicity of operation and access to tight areas for color mark (registration) sensing applications. The R55F is a technological advancement from earlier R55 models. R55F sensors feature TEACH mode sensitivity adjustment, by presenting the light and the dark sensing conditions to the sensor. In addition, sensitivity may be fine-tuned at any time by simply clicking the “+” or “-” buttons on the sensor. The ten-element signal strength light bar clearly displays the relative received signal strength. The bipolar (one NPN and one PNP) outputs may be programmed to include a 20 or 40-millisecond pulse stretcher (OFF Delay), if required. Both TEACH mode sensitivity adjustment and output SETUP are accomplished using the push-buttons on the sensor, or by supplying input pulses via the Remote Teach input. TEACH mode has two options: Static TEACH and Dynamic TEACH. Static TEACH is used to manually set the two sensing conditions individually or to program a specific condition to be sensed (single-point TEACH). Dynamic TEACH provides a means for teaching a series of conditions on-the-fly; the R55F “averages” the sensing events and automatically sets (and periodically updates via the adaptive threshold feature) the switch point between light and dark conditions.
