Fibre optic amplifier with 10 microsecond response rate

November 2014 Sensors & Transducers

Banner Engineering has enhanced its fibre optic sensors product line with the DF-G2 amplifier, which achieves a 10 microsecond response time with 5 microsecond repeatability.

In addition to quick response rates, the amplifier provides an easy-to-read dual digital display for highly visible signal level and threshold values. An intuitive interface ensures simple set-up and programming through displays, switches and buttons, or via remote input teach wire. The DF-G2 also offers complete user control, providing manipulation of all operating parameters, including switch point threshold, light operate or dark operate, various output timing functions, electronic gain level and sensor response speed.

Offering six different Teach and Set methods, operators can achieve optimal gain and threshold selection for each application – particularly for high-speed or low-contrast environments such as small part or clear object detection.

The DF-G2 features thermally stable electronics, which help minimise warm-up drift and enable multiple amplifiers to be mounted side-by-side, with no reduction in the ambient temperature limit. Inherent thermal stability also provides cost-saving advantages by reducing machine start-up time and eliminating production delays due to ambient temperature changes. For additional flexibility, an intricate cross-talk avoidance algorithm allows two fibre optic assemblies to be mounted in close proximity, sensing different features of the same target.
