Magnetostrictive LDT
for High Shock and Vibration Areas

Gemco brand position sensing products have been
known for survival in harsh industrial environments.
We have taken over twenty years experience in
magnetostrictive linear sensors and married it with
our understanding of rugged industrial sensors to
develop the BlueOx LDT as the industry’s first truly
rugged magnetostrictive linear transducer.

The BlueOx LDT is lab tested and field proven to
stand up to high shock and vibration. With test
results of 2,000 Gs of shock and 30 Gs of random
vibration without false signals or mechanical
damage, the BlueOx LDT is ready to perform on the
most demanding applications.

In addition to its ability to withstand shock and
vibration, the BlueOx LDT is rugged in other ways.
Sensing tube construction is welded stainless
steel, suitable for insertion in 5000 PSI hydraulic
cylinders. The electronics are enclosed behind an
aluminum housing with O-ring seals for IP67 indoor
applications (Type Nema 6 rating and stainless steel
covers and connectors are available as a special
option).

The 952 BlueOx is available with Analog, Control
Pulse, Variable Pulse or RS422 Start/Stop outputs.
The 952 is compatible with PLC interface cards
and our 1746 LDT Interface Card. The 16 bit
resolution analog output is programmable over the
entire active stroke length. The units can easily be
changed in the field from a 0 - 10 VDC to a 10 - 0
VDC or a 4 - 20mA to a 20 - 4mA. As an added
feature, the optional differential analog output allows
the distance between two magnets to be measured.

The BlueOx, with its high resolution and rugged
construction, is at home in heavy duty areas such as
lumber mills, steel mills, stamping plants, assembly
automation, material handling, robotics and any
other industry where highly accurate and reliable
continuous linear position sensing is needed.

* If option S or E (environmental connector) is
selected, mating connector and/or pigtail must be
ordered separately.

Note 1: On unsupported stroke lengths greater than
4 feet, rod support bracket(s) and a special magnet
should be used.
Note 2: Specify magnet as separate line item
(standard magnet is SD0400800).
