Special sensor features For special applications or application areas ifm electronic offers Inductive sensors with special features.
K=1 / units without correction factor No matter whether steel, aluminium, copper or other non-ferrous metals: The new “K=1” Sensors from ifm electronic have the same sensing range on all metals as opposed to conventional sensors. K=0 / Ferrous-only The “ferrous-only” sensors feature a selective detection. They only react to ferritic metals. The units do not switch on non-ferrous metal or stainless steel. This feature is particularly useful for machining aluminium. Swarf on the sensing face which leads to spurious switching of conventional sensors is ignored by these units. Units for mobile use with e1 type approval The e1 type approval by the Kraftfahrt-Bundesamt (German Federal Office for Motor Traffic) certifies compliance with the EMC regulations for road vehicles. Units with this type approval are allowed to be mounted on vehicles without invalidating their operating permit. To obtain the e1 type approval the units must comply with special EMC conditions for noise emission and immunity. The EMC compatibility of 100 V/m is well above the requirement of the regulations. Photoelectric sensors The M12 sensor with a focussed, invisible light beam, plus a fixed range of 20 mm on almost all materials closes the gap between inductive sensors and photoelectric Diffuse reflection sensors. The M12 sensor is just as robust and reasonably priced as a standard sensor. A sensing range of 20 mm is achieved when referred to the shade RAL 9005 (deep black, semi-gloss). Referred to the shade “Kodak white” it is 50 mm. Increased temperature range No matter whether it is icy cold or very hot: ifm offers sensors with an increased temperature range of 0 °C...100 °C and -40 °C...85 °C. Setting display for increased sensing range The two-colour LED setting display helps to optimise the setting of the increased sensing range during mounting. The uncertain zone of the sensing range is indicated by a red LED. The assured sensing range, i.e. 81% of the nominal sensing range of a sensor, can be used in an optimised manner. Direct connection to a PLC These two-wire units meet the requirements of the PLC standard for all three categories (1, 1+ and 2) and therefore can be directly connected to the inputs of a PLC. AS-interface Sensors with integrated AS-i slave for direct connection to the field bus. You can find further AS-i components in the separate catalogue “Networking AS-interface”. Analogue sensors Wherever tiny changes in distance require control with a precision of up to a tenth of a millimetre, analogue sensors can be used. Applications are fine positioning or monitoring of the thickness of steel sheets on Presses and stamping Machines. These new sensors safely detect the tiniest distance changes and provide a linear analogue signal.
