■ Contactless, robust system ■ Infinite resolution ■ No hysteresis ■ Linearity 0.5 % or 0.25 % ■ Protection type IP 66 (with cable IP 68) ■ Supply and signal processing through external modules ■ Housing material: Stainless steel (1.4305) Plunger Material: nickel-iron (stainless) Design and function The linear transducers operate according to the differential throttle principle (inductive half-bridges). They consist of two coils which are impermeably cast into a Mu-metal cylinder, where they are protected from vibrations. On displacement through the hollow coil body, a Mu-metal plunger leads to a change in the induction direction in both coils. The linear transducers are designed for an oscillator frequency of 10 kHz. The supply and signal processing are carried out by external modules. Standard measuring strokes: 12, 24, 40, 60, 100, 150, 200 mm Note: Unless otherwise specified, the values apply at an ambient temperature of +20 °C and on use of the transducer with oscillator/demodulator OD15 according to data sheet OD 10220. The housings and plungers are assigned to each other and bear the same serial number. They must not be interchanged.
