Sensors Basic information Sensors are physical-electrical converters, whose task is to acquire measured variables such as distance, pressure and temperature, speed and acceleration and to convert these into an electrical variable. In combination with conrols, these serve for detection of the actual value. Proximity sensors are position sensors that work non-contacting and contactless. They are to a large extent insensitive against environmental influences and do not contain any parts which are subject to wear. We distinguish between switches and analogue sensors. Sensors in machines and plants...

Sensors Connecting variables Power supplies and frequencies Sensors are preferably operated at DC-voltage 24 V. They are, however, designed in such a way that they can be operated within a large connecting voltage range, ranging from 10 V DC to 30 V DC, e.g. at 12, 18 or at 24 V DC. Thus the remaining ripple σ , which is the content of a possibly superimposed alternating voltage, is measured peak to peak and may not exceed 15% of the measured effective value Uv of the supply voltage (according to DIN 41 755). The design of the power supply unit for the voltage supply of the sensors must be stable...

Inductive Proximity Switches Tasks, mode of operation, requirement profiles Mode of operation of Inductive Proximity Switches An inductive proximity switch consists of an oscillator with a resonant circuit, rectifier and an output amplifier. The coil of the oscillating circuit determines the size and shape of the "sensing face” of the proximity switch. The oscillator generates a high frequency oscillation, whose alternating field emanates on the open side of the coil and/or the ferrite core. If a metal piece is inserted into this field, energy is absorbed from the oscillating circuit by eddy...

Inductive Proximity Switches Switching performance Actuating element Standard reference plate Operating voltage Voltage drop Hysteresis Switch actuated M 0V Switch not actuated Residual voltage Sensing face The switching distance s is the distance at which an actuating element (object) approaching the sensing face causes a signal change. The switching distance depends on the size of the sensing face as well as on the size, the shape, and the material of the actuating element. The VDE standard 660 part 208 defines in addition to the application switching distance s the rated operating distance...
