And if you still can’t find the right sensor, SICK offers quick and uncomplicated customized sensor solutions, even with specific customer requirements. With the latest ASIC technology, SICK's sensors offer the ultimate in precision and reliability. Capacitive and inductive proxes are both typically fed by DC power. "productFamily": "Product families", NOTE: This table is intended to understand catalog number designations. To determine which type of sensor you’re looking at, you will typically need to find the sensor’s part number and look it up online. This technology is used in applications where the metal object to be detected is within an inch or two of the sensor face.

The safety switches are not only small and versatile but also provide non-contact operation which keeps wear to a minimum. "productName":"Products", Non-ferrous metal are metals that don’t contain very much iron. We’ll look at how inductive proximity sensors work, how capacitive proximity sensors work, and compare these two types of proximity sensors.

Thanks to intelligent sensors, complex tasks which used to be solved in the control can now be done easily and directly in the sensor.

This can include plastic, glass, liquids, biological matter, and more, Detection of a certain quantity or thickness of material, Liquid detection from the outside of the container, Inductive sensors use a coil to generate an electromagnetic field, With no target present, the field is at its strongest amplitude, When a target is present, the electromagnetic field weakens. ), monitoring the flow of metal parts, counting, etc. Let me know, and maybe I’ll write a post about it! Dank ihrer extrem robusten Bauweise stecken sie hohe mechanische Beanspruchungen durch Schock oder Vibration weg und sind auch sicher vor elektromagnetischen Störungen. The sensor will measure a higher capacitance when a target is present.

SICK is moving into the future every day.

For example, a sensor may provide an output ranging from 2 to 10 volts, DC. Some inductive prox switches have a harder time detecting non-ferrous metals.

Not so for the IMI full metal sensor from SICK. Or maybe you’re getting ready to buy some sensors. We design the sensors to withstand the toughest environmental conditions they are ever likely to experience in operation. When a target passes in front of the sensor, eddy currents form in the electromagnetic field, lowering the amplitude of the field as measured at the sensor. Lastly, plug in your email in the box below. They detect metal objects without contact, and are characterized by a long service life and extreme ruggedness.

(Images from Turck website): Among these, the “barrel” form factor is extremely common.

Proximity Sensors PROXIMITY Tubular Inductive Sensors / Interpretation of Catalog Numbers. Adjustable capacitive proxes can differentiate between material thickness in certain cases. This makes predictive maintenance easier and reduces machine downtime. Among the sensors I see in use, the three most common form factors are shown below. Other sensors on the market have analog outputs. Select from a wide range of different sizes and materials such as stainless steel, VISTAL®, metal, plastic or PTFE coating.

Their range of applications is very extensive and includes : the monitoring of machine parts (cams, mechanical stops, etc.
