The SM263/283 inductive displacement transducers (housing diameter 12 mm) from A.B. Jödden are designed for measuring distances of up to 360 mm, while the SM343 series (housing diameter 10 mm) can measure distances of up to 20 mm. An integrated microcontroller evaluates the axial displacement of the Mu metal core. The complete electronics, which provide an output signal proportional to the displacement, are built into the housing. Thanks to the low current consumption of the newly developed electronics, the inductive displacement transducers are designed in 2-wire technology with an output signal of 4 to 20 mA, which can be processed directly by many evaluation units. An operating voltage of 9 to 32 V(DC) is required. The minimum operating voltage depends on the load resistance. Mechanical attachments, such as ball joints on the plunger and housing, are available. In the push-button versions, the plunger is pressed into the rest position by an integrated spring. The electrical connection is made either via a plug or a watertight molded cable. Protection class IP68 is achieved in this version. The encapsulated design (IP68) allows the sensors to be used even under extreme environmental conditions such as oil mist, mud, rain, dust and high shock and vibration loads.
