SNDJ-H3*-G0* Series
Hall-Effect Zero-Speed Sensors
DESCRIPTION
The H3C and H3L series Hall-effect speed sensors are
designed for use with a ferromagnetic gear or pole wheel to
generate impulse frequencies proportional to the speed of the
target.

POTENTIAL APPLICATIONS
High speed gear tooth sensing
Over-speed detection
Monitor shaft rotation
Detect rotary position of gear or shaft
Position sensing of any ferrous target
The sensors are capable of zero speed and rotational
orientation is independent of sensor function.

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].
•
Using radial or axial mounting, the sensor should be
mounted with the center of the sensor face over the center
of the gear teeth or targets. Using radial sensor mounting,
some axial movement is permissible.
•
A solid and vibration-free mounting of the sensor is
important.
