What Does the IP Rating on an Industrial Sensor Data Sheet Indicate?

Posted by Sean Miller on Tue, Dec 03, 2013

How do you use this rating to select a sensor?

If you have ever looked at all the data sheet specifications listed for a Pepperl+Fuchs industrial sensor, typically you will see a section labeled “protection degree” under the mechanical specifications section. This rating defines how well the sensor will be protected from contact with dust and water.

What Cordset Do I Need?

Posted by Sean Miller on Tue, Oct 29, 2013

Pepperl+Fuchs offers a variety of cables for our quick disconnect sensors, and most of the time, any cable with the appropriate connection will do. But depending on the application, a specific cable type might be needed.

Factories that use sensors for general-purpose applications such as bottle counting and part detection will likely be fine using a standard PVC or polyurethane cable, as these are the most readily stocked and easily affordable cables for use with quick disconnect sensors.

How Do I Use a Cable Pull?

Posted by Sean Miller on Tue, Aug 20, 2013

Types of rotary encoders that work with cable pulls

Cable pulls are devices used to measure the distance traveled on a piece of equipment. You connect cable pulls to a rotary encoder that rotates around a shaft. The encoder sends output signals to a controller. With the data gathered from these signals, you can track the linear distance that the object connected to the cable pull is moving. How accurate this measurement is depends on the pulse count of the rotary encoder.

We offer cable pull models in two sizes. The cable length dictates which drum size and housing size to use. Use a larger housing to fit the longer cable lengths. Cable lengths are designated by the last two digits following SL30. Cable lengths of 1, 2, and 3 meters use the 80 mm x 80 mm housing size. Longer cable lengths use a housing size of 130 mm x 130 mm and up. The specifications list our cable pulls as having an IP65 degree of protection. However, this degree of protection applies only when you have an encoder attached to a cable pull, since there is a seal inside the cable pull. Figure 1 shows a rotary encoder connected to a cable pull.
