BANNER Engineering has announced the new FI22 inline fibre optic sensor, now available from Micromax . Unlike typical fibre optic amplifiers, this sensor is designed to be used without an enclosure and does not require DIN-rail mounting.
Instead, it features a unique snap-mount bracket and adhesive mounting method for infinite location flexibility.
Its rugged, lightweight, low-profile plastic housing and IP67 environmental rating make it suitable for surface-mounting directly on a machine.
When used with Banner Steelskin high-flex stainless steel-sheathed fibres, this "system" provides a robust alternative to expensive and bulkier glass fibre optic systems.
Accurate setup is easy with the visible light beam and the real-time feedback of an 8-segment LED bargraph display.
The FI22 features extremely simple, push-button single or two-point static, and two-point dynamic TEACH programming, plus a manual adjustment mode for fine-tuning.
Single-point static TEACH defines a sensing window centered on a single taught condition and is accomplished in static mode.
Dynamic TEACH is used to program the sensor "on-the-fly" during actual machine-run conditions by taking multiple samples of the light-and-dark conditions and automatically setting the threshold at the required level.
Setup instructions are printed on the snap-mount bracket for easy reference.
The easy-to-see bargraph displays bright LEDs, providing the user continuous feedback during setup and operation, including relative received signal strength, sensing contrast, programming status, and diagnostic warnings.
For maximum efficiency and convenience, one or more sensors can be programmed from an external switch or PLC, via a remote TEACH wire. For added security, the wire can also be used to disable the push buttons.
The unit operates from 10 to 30V dc, and includes reverse polarity protection, two 100mA solid state outputs (Bipolar: one NPN and one PNP), and transient voltage protection.
It features a rugged housing, rated IP67 and NEMA 6. Users can choose from a 2m (6.5') 5-conductor PVC cable, a 9m (30') PVC cable, or 6-pin integral Pico-style quick disconnect.
