BANNER Engineering, represented in Australia by Micromax , has released the D10 series of compact, DIN-rail-mountable fibre optic sensors. It is available with a numeric display, with a bar graph display and in an output-all version. They all have the same housing style and interface format, making them easy to specify and efficient to install.

They are suitable for sensing applications in the metal stamping, materials handling, pharmaceutical, printing and semiconductor industries. They can be used to guide the edge of plastic material as it moves across rollers, to detect the presence of an integrated circuit lead frame in PCB manufacturing or to count bolts dispensed from a feeder bowl in an assembly operation. They can also be used to trigger a vision sensor in an inspection, to map the presence of wafers in a cassette for semiconductor manufacturing, to locate the perforations between bags on a web or to monitor the liquid level in a confined storage vessel.

The sensors use visible red or green sensing beams. They offer low-contrast sensing with automatic Teach options or manual adjustment. Inexpensive, flexible plastic fibres are easily cut to length during installation. Available outputs include bipolar discrete, dual-discrete and analogue/discrete.

The version with a numeric display includes the capabilities of four sensors in a single unit with its four-mode power and speed settings. These settings include high-speed, super high-speed, high-power and super high-power. Models have either two discrete outputs in the same sensor, or a discrete output and either a 4mA-20mA current or a 0V-10V dc analogue output in the same sensor and a highly-visible four-digit Teach/signal strength display. Discrete outputs are programmable for 50μs, 200 μs, 1ms and 2.5ms response times. The analogue output on discrete/analog models has a 1ms response time.

The version with a bar graph display has an easy-to-read, eight-segment light bar display for Teach and signal strength indications. It offers a bipolar discrete output with one current sourcing (PNP) and one current sinking (NPN). Response time in normal mode is 500μs and 200μs in high-speed mode.

The discrete output model offers v12-turn manual sensitivity adjustment and a pulse rate LED for signal strength indication. It also has a bipolar discrete output with one current sourcing (PNP) and one current sinking (NPN). Models are available with either a 200μs or 500μs response time.
