R58B Series Registration Mark Sensor Reduces Complexity and Increases Speed of TEACH Process

Banner Engineering Corp. introduces the new R58B Series Expert Registration Mark Sensor, the latest addition to the company’s line of registration mark sensors. The R58B provides the same high-performance detection and outstanding color contrast sensitivity of the R58E, in addition to a simplified teach process. TEACH is performed quickly via a single-click on the TEACH push-button on the sensor or via remote input. TEACH allows the sensor to “learn” the light and dark sensing conditions, based on user inputs, and then can automatically adjust the sensitivity to place the operating threshold midway between threshold for the light and dark condition. By reducing the complexity and increasing the speed of teaching the mark and the background, the R58B reduces operator training and product change over time.

During the TEACH process, the R58B automatically selects a red, green or blue LED to optimize the application contrast. Then, the selected color is indicated on the user interface, upon which the customer specified color can be set from push buttons or a PLC compatible remote input—providing a streamlined process to enable more convenient sensor configuration and teaching. The TEACH button can be temporarily deactivated by putting the sensor into RUN mode, or, all buttons can be locked out via the remote interface wire.

With superior color contrast sensitivity and sensing performance, the R58B offers registration repeatability and solid-state reliability for typical color contrasts through the following features:

•Capable of detecting 16 levels of gray scale
•Ultra-fast 10 kHZ switching frequency (10,0000 actuations per second)
•Smart gain-control algorithm maximizes performance in low-contrast or high-gloss applications
•11 status LED's indicate sensor configuration and currently selected emitter color

The R58B is cased in an IP67-rated, zinc alloy die-cast housing with high-quality acrylic lens, making it ideally suited for food processing applications. A single output configuration is available (PNP or NPN by model).
