New registration mark sensor has easier teach function
Banner Engineering Corp.‘s R58B Series Expert Registration Mark Sensor, the latest addition to the company’s line of registration mark sensors.
The R58B reportedly provides the same detection and color contrast sensitivity capabilities 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 apparently 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 color contrast sensitivity and sensing, the company said, 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).
