Performance in a mini-package
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.
Banner’s new SureCross Q45 is a self contained, wireless standard photoelectric sensor solution designed for control and monitor- ing applications. Without the large scale requirements, complexities of cables, conduits and installation, operators can now quickly inte- grate a scalable, wireless sensor network to improve efficiency by monitoring and coordinating mul- tiple machines and processes. The SureCross Q45 is well suited for many applications, including cable replacement, moving appli- cations, remote applications and productivity solutions, and has IP67/NEMA 6P protection against liquids and debris common to industrial environments.

The new A1359 from Allegro MicroSystems Europe is a program- mable linear Hall-effect sensor IC with a dual analogue/PWM output that makes it well suited for applications requiring output redundancy. The new device has been designed for use in applications such as dis- placement and angular position sens- ing, that require high accuracy in con-
junction with redundant outputs. This is achieved in the dual tracking output of the A1359, where the PWM output tracks the analogue output to within +/- three percent. The accuracy of the IC is enhanced via programmability on the analogue output pin for end of line optimisation without the added complexity and cost of a fully pro- grammable device. The A1359 features one time programming using non-volatile memory to optimise device sensitivity and to set the quiescent output voltage and duty cycle for a given application or circuit. The sensitivity range of the A1359 is 4mV/G to 9mV/G, and the quiescent analogue output is adjustable around 50% of the supply rail voltage. Optimised performance at different temperatures is achieved by programming the temperature coefficient for sensitivity, quiescent output voltage and duty cycle at end of line test.
The A1359 is targeted at the automotive and industrial markets, with end applications including torque sensing in electronic power steering and position sensing of transmis- sion components, brakes and clutch cylinders. The A1359LLETR-T is available in a TSSOP-08 (suffix LE) surface mount package. Allegro MicroSystems

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. The painstak- ing process of tilting the sensor to detect
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

Increased expansion
Zettlex has announced that it has expanded its IncOder range of precision angle encoders to include a choice of more than 45,000 product variants, includ- ing new IP67 rated sensors for operation in wet environments. The IP67 versions allow users to deploy IncOders in wet environ- ments because the traditional weak spots from cable fittings and con- nectors have been overcome by the use of an integral moulded cable. The IncOder range offers a choice of eight sizes, six different mechanical mounts, eight measure- ment resolutions, ten data outputs, four supply voltages and four con- nector options. Zettlex

Enter 208 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.
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.
