Inductive proximity switches with linear analogue signal
 
 

 
Accurate positioning


New analogue inductive proximity switches from sensor market leader ifm electronic have longer sensing ranges and superb linearity, and thus address drawbacks of earlier generations. Displacement of a metal component by as little as a tenth of a millimetre can be key to fine positioning, or controlling the steel sheets on presses and stamping and welding machines.

These new proximity switches safely detect the tiniest changes in distance and provide a linear analogue signal - depending on the version - with a voltage output (0...10V) or current output (4...20 mA). A special feature is the extremely high repeatability of less than 2% and the linear output characteristics better than 3 % of the final value of the measuring range over the whole operating range.

The sensors are supplied in robust cylindrical M12, M18 and M30 design. The enhanced operating range depending on housing size and mounting type can be 0.2 to 2 mm for flush-mountable M12 up to 1 to 26 mm from the non-flush rectangular version.

The short response time of less than 10 ms (type depandant) allows use of the sensors even in processes requiring fast control.

The wide temperature range of -25...80° C enables the sensors to withstand otherwise critical applications.
