Gefran ONP1-A Data Sheet
ONP1-A
CONTACTLESS MAGNETOSTRICTIVE LINEAR POSITION TRANSDUCER
WITH GEFRAN ONDA TECHNOLOGY (ANALOG OUTPUT)
Main characteristics
• Strokes from 50 to 1500mm
• Sliding or floating magnetic cursor
• Direct analog output for displacement
• Standard valve or M12 connector
• Work temperature: -20...+75°C
• IP65 protection
• Power supply 24Vdc ±20%
Contactless linear position transducer with innovative GEFRAN
ONDA magnetostrictive technology for longer lifetime.
The absence of electrical contact on the cursor eliminates all
wearing and guarantees almost unlimited life.
The new ONDA technology solution (patented by Gefran)
allows to obtain an essential modular structure with compact
size for simple installation.

ONP1-A-M
The ONP1-A magnetostrictive transducers provide a direct 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.
