Arrow right white

Normally open, normally closed or antivalent

Binary switching sensors – i.e. ones that are in either the 'switched on' or 'switched off' state – have three different output functions:

Arrow right white

Switching frequency in the sensor technology context

The switching frequency is the maximum number of switching operations of a sensor per second.

Arrow right white

Sensing ranges of position sensors

The sensing range of position sensors is the distance between the sensing face of the sensor and the approaching measurement object.

Arrow right white

PNP or NPN

PNP or NPN? The question as to the kind of output type is always fundamental when it comes to selecting sensors.

Arrow right white

Temperature-dependent resistance

A platinum measuring resistor is a resistance thermometer used to measure temperature.

Arrow right white

Flush or non-flush for sensors

Flush or non-flush are important specifications of the data sheet of inductive sensors.

Arrow right white

IP protection ratings for sensory systems

Electrical equipment is often used in industrial applications in difficult environmental conditions.

Arrow right white

Protection classes in electrical engineering

Protection classes are used in electrical engineering to prevent electric shock.

Arrow right white

Correction factors for inductive sensors (Factor 1)

What is meant by 'reduction factor' or 'correction factor' in the context of inductive sensors?

Arrow right white

Level monitoring systems

Levels can be detected using various sensor principles.

Arrow right white

The right sensor cable. PUR or PVC?

PUR or PVC? What is actually the difference and which type of cable is best suited for my application?
