Customer Benefits

Ease of use—the R58 Expert is extremely easy to install, setup and maintain

Versatile and dependable—Hamer standardized the R58 Expert and uses it throughout their product line


Hamer, LLC is a Minnesota-based manufacturer of automated packaging equipment for a wide variety of applications and world-wide customers. From pet food to pellet fuels, Hamer machinery packages products in a variety of weights and sizes at speeds up to 60 bags per minute. A vital component of Hamer’s equipment is registration mark sensing—the ability to detect marks on packaging as it passes at high speeds. When a mark is detected, the equipment cuts the packaging at the designated location, eliminating waste and ensuring each bag is consistent.


Many of Hamer’s customers change out their rolls of packaging multiple times a day to suit different product lines. As packaging changes, so do registration marks—they can vary in size, shape, location, color and translucence. Hamer’s previous sensor technology required customers to physically change out the sensor when they needed to detect different colored registration marks. Hamer turned to Banner to find a registration mark sensor that was easy and cost effective to install and less complicated for their customers to maintain.


Banner introduced Hamer to the R58 Expert—a high-speed registration mark sensor. The R58 Expert is designed to read multiple colors on high-gloss and lowcontrast surfaces without changing the sensor—perfect for customers who rotate their packaging webs multiple times a day. With a simplified push-button or remoteswitch TEACH mode, the R58 Expert automatically selects the correct LED color to optimize contrast. Perhaps the best aspect of the Banner sensor is that it’s easy to install, set up and teach, integrating seamlessly with Hamer’s equipment. Because it is so simple to install and maintain, the R58 Expert has become Hamer’s standard registration mark sensor for their automated packaging product line.
