950MD
NPT conduit port for wiring to the LDT or optionally
an MS connector can be installed for the external
wiring. Use of the MS connector will require that
the LDT also have a connector on it in lieu of a
potted cable. This will allow for a quick connect at
the LDT head internally and on the 950MD head
externally. The 950MD head is sealed with O-rings
and also contains two threaded air purge openings
that are plugged but available for use to air cool
the LDT head with filtered and regulated air. By
removing the plugs and installing the proper size
air fittings, you can cool the head electronics for
high temperature applications. An optional Vortex
air cooler may also be specified for the head and/or
barrel or an optional water jacket for the LDT can be
supplied. See the 950MD dimension drawings for
further details .

Due to the fact that the standard Mill-Duty Housing
has a mechanical stroke identical to the LDT
active stroke, no physical over-stroke exists. If
it is possible that the machine being coupled to
can extend/retract beyond the stroke supplied,
damage to the Mill-Duty Housing and possibly to the
machine might occur. To compensate for this we
call out fully retracted/fully extended over-stroke
dimensions for the Mill-Duty Housing. These values
are essentially the additional stroke length added to
the Mill-Duty Housing. The reason they are called
out separately is to alert the user that when entering
these areas, they are out of the LDT active stroke
area. If an extended over-stroke is specified, the
LDT must be ordered with a Dead Band of 5” + X
(extended stroke value). If a retracted over-stroke
is specified, the LDT must be specified with a Null
value of 2” + Y (retract over-stroke value).
The Mill-Duty Housing offers either a conduit
entrance for hard wiring directly to the LDT within
the head or an external connector and mate. The
connector attaches to the LDT inside of the housing
via a small pigtail connector within the head.
Detailed Product Description
and Materials of Construction
The 950MD consists of a 304 Stainless Steel body,
barrel, piston, head and trunnion mount bracket.
The standard 1/2” diameter rod end with mounting
bolt, the 3/4” diameter trunnion mounting bolt, and
some of the optional MS connectors on the head
are the only items that are not Stainless Steel on the
standard assembly. This is also true of the optional
3/4” diameter front and rear rod ends with their
mounting bolts. These rod ends and all mounting
bolts can be ordered in Stainless Steel as an option.
The 12mm Euro connector options C3 and C4 come
standard in Stainless Steel. Consult the factory for
further details.
The 950MD head assembly is removable to allow
installation of a rod style LDT that will screw into
the standard 3/4” - 16 x 1.00 mounting thread. An
optional Metric thread of M18 X 1.5 can also be
supplied upon request. The head contains a 1/2”
