Your Quick Disconnect Sensor Needs One Of These.

If you are using quick-disconnect style sensors (ultrasonic, photoelectric, inductive, capacitive, you name it) then you need a quick disconnect cable!

Where are you buying them from and how much are you paying? I have two excellent options for you:

1. Carlo Gavazzi CONM series of connector cables has pricing that cannot be beat! They also have them in stock. Take a look.

2. Pepperl+Fuchs V1 and V3 series of cordsets are also very competitive and readily available!

Of course, we also can supply just about any sensor you need!

A Great Article Posted from Baumer!

I thought you might enjoy this article recently posted from Baumer. We currently have the O500 photoelectric sensors posted online, we'll be adding the ultrasonic sensors as well!
What’s so cool about the NextGen U500 Ultrasonic Sensors?
By Corey Loeffelholz - Business Development Manager 

Baumer announces the new U500 NextGen ultrasonic sensors from Baumer, featuringOneBox Design, qTeach, which are also available with their O500 photoelectric sensor cousins. Before we get to what's so cool about the U500 series, let’s start by discussing what ultrasonic sensors are all about. 

Instead of sending and receiving light like photoelectric sensors, ultrasonic sensors emit and receive sound.  The sound that they throw off is a really high frequency, in the range of 120 kHz to 400 kHz.  That’s far beyond what most people can hear, which usually falls in the 20 Hz to 20 kHz range.  

Inside they have a transducer which acts as both a loudspeaker and a microphone.  The transducer emits pulses of sound and then stops.  After the transducer stops vibrating, which takes a small amount of time, the sensor begins to listen for the echo from the pulses it just emitted.  It can calculate the distance of an object by measuring how long it takes for the echo to return. 

Because the loudspeaker takes some time to stop vibrating before the sensor can begin to listen, ultrasonic sensors have a blind area close to them.  This can be quite a large area on some sensors, but Baumer’s U500 is relatively small – only 100 mm.  Thanks to the integrated electronics, the U500 is quick with a response time of only 50 or 80 ms depending on the version. 

So, why would we use an ultrasonic sensor over a photoelectric?  Ultrasonic sensors work great in environments with a lot of dirt, mist, or vapors that can give photo sensors all sorts of trouble.  Since they’re not using light, color makes no difference to them.  Shiny objects, clear objects, liquids – no problem with ultrasonic sensors. 

Baumer’s newest NextGen sensor, the U500, represents a great addition to our already extensive ultrasonic sensor portfolio.  It’s already proving itself as a powerful product both in price and performance.  The U500 comes in three flavors:  A reflective barrier, a proximity sensor, and a distance measuring version. 

All three adhere to the OneBox Design philosophy in the 500 size.  They share the same housing with the O500 photoelectric sensors.  They all also have qTeach, just like the O500.  The U500s have a full meter of sensing distance, which compares favorably to many competitors. 

The reflective version acts very much like our groundbreaking SmartReflect sensors.  You teach it the background, and the sensor detects anything that returns an echo that differs from the background.  It creates a barrier of sound; break the barrier, get a signal. 

The proximity version of the U500 doesn’t require a background.  You teach it an object, and it detects anything that is that close or closer.  It also has a window teach function which allows you to make the sensor not only ignore objects too far away, but also objects too close. 

The distance measuring U500 provides an analog output, either 0-10 VDC or 4-20 mA.  It has an adaptive output feature which automatically detects if it should be delivering a voltage or current output. The same sensor does both, and it automatically configures its own output.  It’s a great feature, and customers love the versatility and ease of use.  

Ultrasonic sensors solve a lot of applications that can give other technologies problems.  The U500 is the new leader in ultrasonic technology.

Every Quick Disconnect Sensor Needs One.

Do you use quick disconnect versions of inductive or capacitive proximity sensors? Photoelectric sensors? Ultrasonic sensors?

Every quick disconnect sensor needs a quick disconnect cordset! You might call them cable connectors, cordsets, M12 connectors or any number of other names.

The bottom line is... we have them!

Carlo Gavazzi recently introduced an extremely competitive line of M8 and M12 AC and DC cordsets.

Who Is Pepperl+Fuchs and How Do I Say It?

Let's start with how to say it - it's pronounced ''pep earl and Fooks'. Now that you can say it... who are they?

Pepperl+Fuchs (all together now... pep earl and fooks!) was founded in 1945 by Walter Pepperl and Ludwig Fuchs. Yep, the name now makes sense.

Pepperl+Fuchs was originally a radio repair shop but by 1948 they were expanding into other electronic production. This lead to the first proximity switch in 1958 and the first transistor amplifier with an intrinsically safe control circuit!

Pepperl+Fuchs is now a leading manufacturer in sensing technology, intrinsic safety and explosion protection technology. Pepper+Fuchs has around 5,400 employees worlwide and develops, manufactures and provides services in Europe, America and Asia.

Marshall Wolf Automation highly recommends the quality and value of this line. Take a look and learn more.

Sensors for Wet Environments? Yes!

Many Pepperl + Fuch's inductive proximity sensors have an IP rating of IP67 or IP68. Here's some information about what IP ratings mean from my friends at P+F:

The IP (ingress protection) rating is a standardized test method to determine the product's protection against contact, the intrusion of foreign materials, and the ingress of liquids.

To understand the protection level of sensors working in an environment exposed to liquids such as water, we look at the second digit of a specific the IP rating, for instance IP6x. The most common IP ratings for sensors used in in submersed water locations would be IP67, IP68, and IP69K. 

According to a study, the better test for water exposure is the combination of IP68 + IP69K test. This combines the submersion test with the water pressure test to qualify the design against water entering the sensor housing under more extreme cases. The IP68 test qualifies the sensor for indefinite immersion in one meter of water. Take note, however, that as the water depth increases the water pressure on the sensor surface also increases. This is one factor that limits usable underwater depth. Since all of Pepperl+Fuchs sensors are 100% resin filled, which protects the internal components, they will have the ability to survive water resistance under varying circumstances for longer periods.
