Two new families of sensors
from Rockwell Automation address the most demanding applications in the food
and beverage industry. These sensors withstand high-pressure and
high-temperature wash downs, while offering excellent resistance to corrosion
and damage caused by harsh cleansing agents.
The
42CS photoelectric and 871TS inductive sensor families feature stainless steel
construction, extended temperature ratings and IP69K enclosure ratings. IP69K
testing replicates the steam-cleaning process typically used in the food and
beverage industry. This testing requires the sensors to withstand spray
pressure up to 1,450 psi and temperatures up to 176F.
In
addition, both sensor
families have been subjected to and certified to pass
chemical compatibility testing by two independent labs, both of which are
worldwide leaders in the development of cleaning and sanitizing products. In
testing, the sensors were subjected to some of the most commonly used caustic
cleaning agents and disinfectants in the food and beverage industry.
The
PHOTOSWITCH 42CS sensor family features a choice of a smooth or threaded 18mm
316L stainless steel housing with a hard plastic lens for enhanced reliability
and long service life, as well as an operating temperature range of minus 25 to
85C. Smooth barrel models are designed to minimize the accumulation of
undesired particles on the sensor's body and to allow easier cleanup.
An
innovative ferromagnetic teach feature minimizes the possibility of water
ingress associated with the use of push button or potentiometer adjustment.
This feature, offered on select sensing modes, allows users to easily adjust
and optimize the sensing range to meet specific application demands.
The
42CS sensor family
offers polarized retro-reflective, diffuse, transmitted beam, clear object
detection and background suppression sensing modes. A background suppression
sensor is specially designed to detect shiny objects that often go undetected
by other such sensors if the object is approaching at a slight angle. A
stainless steel bracket is offered for mounting of smooth-barrel sensors.
The
871TS inductive proximity sensors feature a stainless steel 316L barrel and an
FDA-certified polyphenylene sulfide plastic face that protects against
chemicals and other corrosive agents. Sensors are offered in 12mm and 18mm
diameter threaded cylindrical enclosures with operating temperature range of
minus 40 to 80C. For added application flexibility, standard and extended range
units are available.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
