Sensors Promise Easy, Low-Cost Registration-Mark Detection

For detecting registration marks in printing and material registration applications often found in the web printing, product packaging, and pharmaceutical industries, the R58A series registration-mark sensors feature simple setup via potentiometer adjustment of the switching threshold and switch-selectable light/dark operation. The sensor also features a short warm-up period, 10-kHz switching frequency, and a15-ms repeatability. The component comes in a rugged metal housing measuring 1.2 mm x 3.8 mm. Additionally, a single emitter color, red or green and specified by model number, ensures that the preferred light source is used every time. BANNER ENGINEERING CORP., Minneapolis, MN. (888) 373-6767.
