Banner's clear object sensors

August 2009 Sensors & Transducers

Robust, easy-to-use clear object detection.

Banner Engineering has introduced the WORLD-BEAM QS30 clear object sensor to provide reliable clear object detection in challenging applications. The sensor utilises an advanced optical design to allow it to distinguish translucent materials, ensuring dependable detection of clear targets including PET bottles and glass containers. Additionally, the optical design prevents the sensor from being fooled by reflections enabling detection of optically engineered surfaces such as mirrors, LCD glass with polarising films and semiconductor wafers.

“Detecting clear objects is a difficult sensing challenge in many real world situations,” says Dennis Smith, technical marketing engineer at Banner. “The optical design of the clear object sensor controls how the emitted light strikes the reflector, preventing false light signals from reaching the photo-detector. The stable and controlled optical path allows the sensor’s microcontroller to detect small changes in the light level, so even clear objects that alter the light level only slightly will activate the sensor. It is a very sensitive and highly reliable detector.”

The unit is easily configurable using either the pushbutton on the sensor or the remote input. Users can select from one of three switching thresholds – light, medium or dark, depending on the target’s transparency level – to optimise detection and maximise sensing stability. The sensor also features an automatic compensation algorithm, which adapts the switching threshold to the sensor’s environment in realtime. Small changes due to dust or contamination on the sensor and reflector or small changes caused by ambient temperature shifts are filtered out by the microcontroller. These features ensure long and trouble-free sensor operation.

Applications

The WORLD-BEAM QS30 clear object sensor delivers high-accuracy clear object detection in a wide range of applications, including:

* Bottle jam detection, bottle counting, and bottle down detection.

* Food processing and packaging machines.

* Plate glass or clear web detection.

* Semiconductor wafer detection.

Features

These are the features that make the clear object sensor particularly useful in the applications:

* Rugged housing for harsh environments; IP67 rated, 1200 psi wash-down per NEMA PW12.

* Automatic compensation algorithm compensates for dust or contamination on the sensor or reflector and for ambient temperature changes.

* Range of 100 mm to 2 m with fast 0,5 ms response time.

* Easy-to-read bar graph display for configuration and status monitoring during operation.

* Visible red emitter beam for simple alignment.

* Compact standard housing.

* 10 to 30 VDC operation.
