A focus on easy set-up and configuration, stable sensing performance, and competitive pricing all guided the development of the new DF-G1 Expert™ Dual Display Fiber Amplifier from Banner Engineering Corp. The DF-G1 series features two bright digital readouts, a thermally stable and high performance electronic design, an improved fiber clamp, and a new, more intuitive user interface. This dual display fiber amplifier expands the range of applications and customers Banner can serve with plastic and glass fiber optic assemblies. Such applications include small part or wire break detection on electronics assembly machines, pill and caplet counting, and high-speed detection for registration mark or product leading edge detection, to name a few.
"What we've done with the DF-G1, is bring all of Banner's application knowledge and advanced sensing algorithms to the customer with the benefit of a dual digital display for ease-of-use and application monitoring," said Dennis Smith, Technical Marketing Manager at Banner Engineering. "The two displays and the rocker button are an intuitive user interface that simplifies sensor set-up, and provides the current light level and threshold values at a glance. And with Banner's extensive experience developing custom fiber assemblies, we can support OEM machine builders around the world with custom fiber solutions and custom amplifier configurations."
The DF-G1 is powered by a high performance 32-bit microprocessor with a 12-bit analog-to-digital converter. The user has full control over all operating parameters, including switch point threshold, Light Operate or Dark Operate, various output timing functions, electronic gain level, and sensor response speed. The operator can use full manual control or one of six Expert TEACH and SET methods to ensure optimal gain and threshold selection for all applications, especially low contrast applications, such small part or clear object detection. Response speeds of 200 µs (High Speed), 500 µs (Standard Speed), 2 ms (Long Range), and 5 ms (Extra Long Range) allow the operator to optimize the DF-G1 for fast low contrast applications or to maximum the sensing range for long distance applications, such as part in place verification.
Another key benefit of the new DF-G1 is the thermally stable electronics which minimize warm-up drift, and allow many amplifiers to be mounted size-by-side with no reduction in the ambient temperature limit. Thermal stability pays dividends in both reduced machine start-up time, and it eliminates production delays due to ambient temperature changes which may affect some sensors. Furthermore, a robust cross talk avoidance algorithm allows two fiber optic assemblies to be mounted in close proximity sensing different features of the same target for many applications.
Banner Engineering offers a broad array of robust SteelSkin™, high flex plastic and glass fiber optic assemblies for mechanically challenging or high temperature installations. The sleek 10 mm wide housing mounts to 35 mm DIN rail maximizing the number of sensing points available in the cabinet. The bright dual displays of DF-G1 are easy to read showing both the light signal level and threshold simultaneously. An ECO (economy) display mode reduces amplifier power consumption by 25%. The highly visible red LED sensing beam makes for easy alignment to the target, and the lever action fiber clamp provides stable, reliable, and trouble free fiber clamping.
