Sunfab Hydraulics has
announced a new speed sensor
for its SCM Series compact
piston motors. The two-channel Hall
effect sensor, PNP, allows customers
to accurately check and control the
rotational speed and even the
direction of the hydraulic motor.

“We started by conducting a
comprehensive competitive analysis
and then looked at the demands of
our customers and made an in-depth
assessment of where best to place the
sensor on the motor,” says Anders
Norberg, project manager. “We’ve
also spent a lot of time and effort
doing field tests, to ensure both
functionality and quality.”
The sensor has two frequency
outputs, which both give square
waveform signals, phase shifted ~90°.

It can be used at high temperatures.

The speed is detected by the cylinder
block’s teeth and, since the sensor
operates with two channels, the
direction of rotation can also be
determined. Motors prepared for
speed sensors can easily be retrofitted
with sensors.
