CONTACTLESS MAGNETOSTRICTIVE LINEAR POSITION TRANSDUCER
(ANALOG OUTPUT)
Main characteristics
• Strokes from 50 to 1500mm
• Sliding or floating magnetic cursor
• Direct and reverse analog output for displacement
• Standard valve or M12 connector
• Work temperature: -20...+75°C
• IP67 protection
• Power supply 24Vdc ±20%
• Electromagnetic compatibility EMC 2014/30/EU
• Compliant to the directive RoHS 2011/65/EU
Contactless linear position transducer with magnetostrictive
technology for longer lifetime.
The absence of electrical contact on the cursor eliminates all
wearing and guarantees almost unlimited life.
Direct and reverse signal for a wide flexibility of use.
The high performance in terms of EMC immunity make the
WPG series suitable for use in industrial environments with
presence of electromagnetic interferences.

ANALOG OUTPUT
The WPG-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.
