MAGNETIC ANALOG ABSOLUTE SINGLE TURN ENCODERS, AHM3 RANGE MAGNETIC ANALOG ABSOLUTE SINGLE TURN ENCODERS, AHM3 RANGE
 With its 30mm size and a 6mm solid shaft, AHM3 encoder characterizes itself by its strong
robustness of the mechanical and electro-magnetic parts, it’s the most compact really
industrial encoder with a solid shaft.
 Application fields : agriculture, construction, forestry vehicles, medical applications, solar
panels…
 Magnetic technology, contactless.
 Available resolution up to 12 bits per revolution.
 Power supply from 10 to 30Vdc.
 Available output interfaces : 0..10V, 0.5..4.5V, 4..20mA.
Also available : PWM, SSI and CANopen outputs.
 Available in option : Extended temperature range (up to -40..+125°C), IP67, angular ranges
and output levels, redundancy…
