WPA-S
CONTACTLESS MAGNETOSTRICTIVE LINEAR POSITION TRANSDUCER
(SYNCHRONOUS SERIAL OUTPUT)
Main characteristics
• Optimised mechanical structure
• Strokes from 50 to 4000 mm
• Fast installation by mean of steel brackets
• Sliding or floating magnetic cursor
• Synchronous Serial Interface direct to controllers
• Output data resolution available from 0.5 to 40 μm
• Data format: binary or Gray code; incremental/
decremental
• Power supply 10...32 Vdc
• Resistance to vibration (DIN IEC68T2/6 15g)
• IP67 protection
• Work temperature: -30...+90°C
• Electromagnetic compatibility EMC 2014/30/EU
• Compliant to the directive RoHS 2011/65/EU
Contactless linear position transducer with HYPERWAVE
magnetostrictive technology, with RS422-SSI digital output interface.
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.
