IK4A (with ONDA technology)
CONTACTLESS MAGNETOSTRICTIVE LINEAR POSITION
TRANSDUCER (ANALOG OUTPUT)
Main characteristics
• ONDA technology
• Optimized mechanical structure
• Strokes from 50 to 4000 mm
• Wide range of connectors for the electrical connection
•
Rod, nipple, exagonal flange AISI 316
• Work temperature: -30°…+75°C
• Resistance to vibrations (DIN IEC68T2/6 12g)
• Power supply 24Vdc ± 20%
• Protection IP67
Contactless linear position transducer with ONDA magnetostrictive
technology.
The analog interface, available with various output ranges in voltage
or in current, guarantees simpler installation and easier adaptation to
existing systems.
The absence of electrical contact on the cursor eliminates all wear
and guarantees almost unlimited life.
The IK4 mechanical structure introduces some innovations for using
in-cylinder, including free rotation of the connector head.

(machine ground)
The magnetostrictive transducers of the IK4A series supply
a direct analogue output in voltage (0...10Vdc) and current
(4...20mA and 0...20mA).
All the outputs can have reverse action (10...0Vdc; 20...4ma;
20...0mA).
The outputs are direct, no signal conditioning is required if they
are interfaced with a controller or measuring instrument.
