AutomationDirect has expanded its sensors offering to include wide area sensors for object detection. The new area sensors from Micro Detectors (MD) are multi-beam, through-beam sensors with emitter and receiver elements used for detecting the presence of any object by sensing the light beam intensity returning from the receiver. The area sensors have an IEC IP67 ingress protection rating.
These MD area sensors are available in basic and advanced versions. CX0 Series basic area sensors have a sensing distance of up to 6m and a detection height up to 320mm. CX2 Series advanced area sensors also have a sensing distance of up to 6m with detection height of up to 960mm and offer analog outputs and a blanking function.
Available Teach-in functions with two levels of adjustment are used for product setting, adjustment and blanking. LEDs indicate the sensor status, alignment, optics condition and faults. Fine Teach allows smallest object detection. Gross Teach avoids potential stability and repeatability of performance problems and is less sensitive to environmental conditions. The blanking function (CX2 series) allows the height of the active optic window to be adapted to the application by eliminating ("blanking") pairs of beams and can be useful in specific situations.
The Emitter emits near-infrared light at non-dangerous levels. The device is classified as RG0 (exempt) according to IEC 62471: 2008-09.
MD area sensors have a 3-year warranty and are cULus, CE, RoHS rated. Area sensors are not protective devices and should not be used to guarantee personnel safety.
In this HOW TO video, we will cover the basics of wiring and setting up one of AutomationDirects Advanced Area Sensors from the brand Micro Detectors. I am currently using model number shown: CX0E1RP-10-016V. These come as a pair with an emitter and a receiver. The Micro Detector area sensors we sell at AutomationDirect all require a connecting cable. Make sure you select the correct cable with correct number of pin outs in either a straight or a ninety degree connector. The sensors I am using require a 4 pin 12mm connector cable for the Emitter and a 5 pin 12mm connector cable for the receiver, I am using the part numbers listed on the screen. Keep in mind; we sell many cables that will work depending on your application and environment. We have 90 degree connectors, straight connectors; harsh environment insulation, shielded cables and they all come in many different lengths. Just make sure you select the correct number of poles or pins for your sensor. If you have questions, use a multi meter and check the pinout or call our free technical support here at AutomationDirect. I follow the wiring diagrams for these sensors, it can be found in the documentation that comes with the sensor, or you can find it on our website. The emitter has 4 connections. Brown for positive voltage and Blue for negative voltage or common to power the sensor. Black should be connected to a switch or device to allow for Gross or Fine Teach functions. Last, White should be connected to the Gray wire on the Receiver. Now let's wire the receiver. The receiver has 5 connections. Brown for positive voltage and Blue for negative voltage or common to power the sensor. The Black wire on the receiver should be connected to your output device and wired as PNP. In this example I have the black wire connected to the positive input on a WERMA Stacklight that we sell here at AutomationDirect. Make sure you check the specs of your device: I am using an LED indicator because the Incandescent light required more current than the sensor supplied, so we would not see an indication. Next is the White wire: it should be wired to a switch or device to select Normally Open or Normally Closed outputs. Last, Gray should be connected to the White wire on the Emitter. Now that our Emitter and Receiver are both wired, we need to check for alignment. The user manual describes how to properly align the emitter and receiver and what errors to detect if they are out of alignment. The manual also explains which LED's you will see if your system is not wired properly. We can now power the sensors and check for operation. Once we power up, there is a time delay or "time delay before availability". Once powered up and ready we can setup the sensor. When the sensor is first powered up, we should only see a Blue LED on the Receiver and a Yellow and Green LED on the Emitter. Right now we have no power applied to the NO/NC feature, so the sensor defaults to normally open meaning there is no output until the sensor detects a part. As you can see, when the sensor detects my screwdriver, our WERMA stacklight green light turns on and also I see a yellow and red LED indication in the Receiver. Making changes to the NO/NC only takes place on power up. If I attempt to change the setup after the sensor is powered up, nothing will change. I must power down, select NC and repower the system and now my green stacklight stays on and I also see a Blue and Yellow LED in the Receiver when no part is detected. Once a part is detected, the green stacklight turns off and we see a Blue and Red LED in the Receiver. Now let's discuss the Teach function. This was where we wired the Black wire on the Emitter to a switch with either positive or negative input to the sensor. Teach allows us to adjust for fine or gross sensing. As you see, when I select Fine or Gross, the yellow LEDs on the Emitter will blink until the sensor has calibrated. Let's discuss quickly what Fine and Gross settings are: Gross Teach is used to detect opaque objects and semitransparent objects with textured or corrugated surfaces. Fine Teach is used when detecting small objects, or transparent smooth objects like glass. How you setup your sensors will be determined on your environment and what type of objects you are detecting. Now our sensors are mounted, wired, setup, aligned and programmed and is ready to start detecting product. Now, what should we detect?? I hope this how to video was useful.
