Mounting Speed Sensor
Use bolts or self-tapping screws to mount the bracket so
that the sensor is aligned directly over the magnet. (Bracket
may be attached by other means such as welding.) When
the wheel or drive shaft begins turning, a speed impulse is
sent to the MT-3405 M console every time a magnet passes
by the tip of the speed sensor. For the speed sensor to
operate properly, the spacing between the magnets and
the tip of the sensor must always remain constant. Before
permanently mounting any parts, be sure that the location
you have selected will meet the following requirements.
See Illustration 9.
CAUTION: To ensure that no console damage occurs,
disconnect all system cables before welding.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the MT-3405 FTW may be interfaced with a va ri ety of
other speed sensing equipment. Several options are listed
below.
ASTRO SERIES OR OTHER GPS SPEED SENSOR INTERFACES
The MT-9000 may also be used with most GPS speed sensors
that output a pulsed signal, such as the Micro-Trak Astro
II and 5, SkyTrak or Dickey-John GPS speed sensors. An
adapter cable may be required.
VANSCO
™
RADAR SPEED SENSOR
The Vansco radar speed sensor uses a microwave (radar)
signal to deliver a reliable, accurate speed signal for electronic
equipment. It features state-of-the-art electronic design/
manufacturing, rugged aluminum housing and complete
testing and certification.
RADAR INTERFACE
The MT-9000 may also be interfaced with most popular
radar ground speed sensors. An adapter cable is re quired for
proper interface.
SEE APPENDIX H FOR LIST OF ADAPTER CABLES FOR RADAR.
GPS SPEED SENSOR INTERFACE
The MT-9000 may also be used with most GPS speed sensors
that output a pulsed signal, such as SkyTrak or Dickey-John
GPS speed sensors. An adapter cable may be required.
