SNDJ-D3*-G01 Series
Differential Hall-Effect
Speed Sensors
DESCRIPTION
The Hall-effect speed sensors are designed for use with a
ferromagnetic gear or pole wheel to generate speed
proportional impulse frequencies.
They exhibit dynamic function, whereby pulse generation down
to 5 Hz is specified. The sensor must be oriented against the
pole wheel as described in the orientation/mounting dimension
drawings on page 3.

NOTICE
INSTALLATION INFORMATION
•
The sensor wires must be laid as far as possible from
large electrical machines. They must not run parallel with
power cables. The maximum permissible cable length is
20 m [65 ft].
•
The sensor should be mounted with the middle of the face
side over the middle of the pole wheel. Where the pole
wheel has teeth or slots with radial sensor location, the
sensor would normally be mounted over the center.
Dependent upon the wheel width, a degree of axial
movement is permissible.
•
A solid and vibration-free mounting of the sensor is
important.
