Main characteristics
• Optimised mechanical structure
• Strokes from 50 to 2500 mm
• Sliding or floating magnetic cursor
• Availability of several analogue outputs (voltage or current)
for direct position and speed measurement or reverse
measurement (only position)
• Single or double cursors models availability
• Power supply 24Vdc ±20%
• Resistance to vibration (DIN IEC68T2/6 12g)
• IP67 protection
• Work temperature: -30...+75°C
• Electromagnetic compatibility EMC 2014/30/EU
• Compliant to the directive RoHS 2011/65/EU
Contactless linear position transducer with HYPERWAVE
magnetostrictive technology.
The absence of electrical contact on the cursor eliminates all
wear and guarantees almost unlimited life. High performance in
terms of environmental IP protection and EMC immunity.
High accuracy of the mesurement with reference to the non
linearity, repeatability and hysteresis. High resistance to
vibrations, mechanical shocks for use in a harsh industrial
environment.

ANALOG OUTPUT
The WPP-A
magnetostrictive
transducers provide a
direct and reverse voltage
or current analogue
output proportional to the
magnetic cursor’s position.
Since the output is direct,
no signal electronic
processing is required if
interfaced with controllers
or measurement
instruments.
