Products Sensors & Sensing Systems No compromise on accuracy
A new family of miniature pho- toelectric sensors has been introduced by Carlo Gavazzi. Suited to applications where high accuracy of detection is critical, the PD30CN features the latest technology in back- ground suppression which improves accuracy of the detec- tion of colours and has a sensing range of 200mm, diffuse reflec- tive, retro-reflective, with or without polarisation and through beam sensors which are used to detect objects either by reflection or interruption of the emitted light beam.
The background suppression model uses active pixel sensor’s (APS) CMOS array of 64 x 1 sensor with each pixel repre- senting a specific position. The biggest advantage of a CMOS sensor is that it is immune to the blooming effect where a light source has overloaded the sensitivity of the sensor, causing the sensor to bleed the light source onto other pixels.
NEW Presence Detection Measurement High performance fl exible sensor platform
Its standard IP67 housing is only 10.8 x 20 x 30mm and is manufactured in a reinforced PMMA/ABS. This includes a manual potentiometer for easy set-up and easy adjustment, NO and NC outputs and NPN and PNP versions, plus a rated oper- ating voltage of 10-30V DC (including ten percent ripple), voltage drop of 2V DC at a maxi- mum load, and an output cur- rent of 100mA.

Well suited for high speed packaging processes, SICK’s new SICK KTM offers maximum contrast detection reliability in a mini-sensor. It achieves fast paced print mark detection with short response times and fine grey-tone resolution, even where media is shiny.
With the SICK KTM contrast sensor, print marks are detected on a wide range of packaging media, including reflective materials such as high gloss foils or where contrast levels are low. Therefore, it is well suited to high speed packag- ing, food and drink, cosmetics, printing and other commercial wrapping and labelling operations.
Whether black or white, colour, matte or shiny, print marks are reliably detect- ed, even where there is a minimal differ- ence in brightness between the print or contrast marks and the background. As well as differentiating between black and white, the sensor has a fine resolution of 20 grey-tones to cope with a range of shades, so even minimum levels of con- trast are detected. The SICK KTM’s short response time of 35µs and wide dynamic range enable precise switching signals and positioning accuracy at high throughput speeds. Easy to mount, even in restricted spaces, the SICK KTM’s high speed capability means the housing can be mounted per- pendicular to the medium.

shiny materials is only necessary in exceptional cases.
The SICK KTM has two variants, the
Core and Prime - the KTM Core is well suited for standard applications while the KTM Prime is suitable for more challeng- ing applications.
All KTM Prime sensors have a dynamic teach-in function so that material flow does not need to be inter- rupted. Format changes can be com- pleted quickly and easily by retrieving the parameter setting of previous jobs from the controller’s memory. SICK
