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" 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.
