HS35M
DESCRIPTION
The Avtron Model HS35M Magnetic Hollow Shaft Incremental Encoder
is a speed and position incremental transducer (also known as a
tachometer or pulse generator). When mounted to a motor or machine,
its output is directly proportional to shaft position (pulse count) or
speed (pulse rate). The HS35M operates down to zero speed and can
be used for both control and instrumentation applications.
The HS35M employs a hollow shaft and clamping collar to lock the
encoder to the shaft. A high-performance resin housing provides
electrical isolation from motor shaft currents. An optional hollow shaft
insert permits 1" models to fit a broad range of shaft sizes from 1/2"
to 1" [12mm - 20mm]; 1 1/8", 25mm, and 30mm dedicated models
are available. An anti-rotation bracket prevents rotation of the encoder
while allowing for shaft end float and axial movement.
