Note mounting dimension drawing (Figure 1)

for hole locations.

The LSX has the same mounting and tracking as

the original MICRO SWITCH explosion proof

limit switch (the ML-El). The ML-El has been a

standard in the industry for many years and the

LSX is interchangeable. The LSX may be mount-

ed with two 1/4 inch screws from the front, or

from the back with two 5/16 inch screws. See

figure #1.

HDLS MOUNTING

If it is desired to mount on existing HDLS mount-

Listing LSXZ4022) must be used. The adapter

plate is attached in the HDLS location. Position

recesses provided. Now simply attach the LSX

temperature before they reach explosive gases

of the standard HDLS head.

The LSX enclosure is sealed for protection

against corrosion, water, dust and oil as defined

enclosures also met NEMA standards for

and D and type 9 Class II Groups E, F and G.

explosion proof plus sealing requirements are

To comply with explosion proof requirements

the LSX has flame paths within the housing

which cool exploding gases below the kindling

surrounding the housing. Flame paths on the

LSX are (1) an extended plunger between the

switch cavity and head and (2) the cover-housing

threads on the front of the switch. Liquid sealing

is accomplished by an O-ring seal located out-

side the threads and the same field proven seals

in NEMA 1, 3, 3R, 4, 4X, 6, 12 and 13. These

MICRO SWITCH explosion proof switches are

designed specifically for use in hazardous loca-

tion applications. For a general description and

classification of hazardous atmospheres refer to

MICRO SWITCH Catalog 40. In addition to

meeting explosion proof requirements the LSX

meets additional liquid sealing classifications.

This makes the LSX ideal for outdoor use or in

needed.
