vailable from Countapulse Con-

trols, the new Leuze KRT 18B

contrast sensor is a flexible multi-

colour device that uses the three

LED colours of red, green and blue to

automatically determine the colour that

produces the maximum contrast with the

detected mark.

A significant feature is that reliable

detection is possible even on glossy sur-

faces or when marks are faded. This is due

to the automatic sensitivity readjustment.

Equipped with a high switching frequency of

up to 22 kHz, shortened response times are

possible when using the Leuze KRT 18B. An

alignment aidon the13mmfocal pointmeans

the sensor can be easily aligned and rapidly

put into operation.

Different models of the sensor are avail-

able for simple switching point adjustment

and each incorporates a self-adjusting bar

graph for optimal display of the signal quality.

One variant of the Leuze KRT 18B has two

teach buttons for calibration on background

andmark, while another has a potentiometer

and a colour selection button.

These features make reliable functional-

ity possible with just a single setting, even

where there is a high contrast on the mark.

Changes to the foil format on packaging

machines, for example, can be quickly and

easily adapted using the integral IO-Link

interface of the sensor. The device is housed

in an ECOLAB tested housing that is rated to

IP 67 and IP 69.

Countapulse Controls, the official Leuze

distributor for southern Africa, is able to

assess any sensing application and provide

a fit-for-purpose solution that will meet the

specific needs of an operation. The company

also offers a 24/7 hotline to assist end users

with technical challenges that may be experi-

enceddue to lackof knowledgeor experience.

Precise detection with laser sensors

Countapulse Controls also offers a range

of laser sensors that are capable of reliably

identifying small objects, accurately measur-

ing dimensions and positioning these where

required. Use of Leuze laser sensors that

incorporate highly directional light beams

facilitatesoptimumreliability for theenduser.

Alignment is simplified using a small light

A new contrast sensor that combines product usability with high performance has been added to

the Leuze sensing solution product line-up. Ideally suited to packaging processes, the innovative

sensor will provide reliable detection in foil bag packaging machines as well as for label detection

in filling systems. In addition, the need to precisely detect small parts and accurately position these

has increased in demand of late as many products become ever smaller in size.
