Datasheet

MICRO SWITCH™ LSX Series

Hazardous Area Limit Switches

MICRO SWITCH™ LSX hazardous area switches are designed for use in adverse environments. They are approved for use in

hazardous locations and NEMA classiﬁed atmospheres because their rugged housings have integral ﬂame paths. These ﬂame

paths force internal expanding gases to cool below external atmosphere ignition temperatures before they leave the housing. The

LSX also features tracking interchangeability with MICRO SWITCH™ BX Series Hazardous Area switches. An optional mounting

plate provides the same tracking and mounting as the standard HDLS Series (heavy-duty limit switch).

The majority of HDLS operating heads and circuitry options are available for the LSX Series. The rotary actuated LSX series

products are designed for use with levers that have non-sparking actuators due to the potentially hazardous environment. The

other styles of LSX Series switches which are the plunger actuated and wobble actuated products incorporate an integral non-

sparking actuator.

What makes our switches better?

DESIGN FLEXIBILITY

Features

and Beneﬁts

MICRO SWITCH™ LSX limit switches’ field adjustability (CW-CCW operation,

rotatable operating head) assists in matching the switch to the application.

Available with momentary, maintained, sequential, or center neutral action.

All-metal drive train for consistent operation

UNIQUE DESIGN FEATURES

The head design is keyed for more secure head-to-body retention with the

head indexable in any one of four positions 90° apart. Captive mounting screws in

the heads help prevent the loss of screws during replacement or repositioning of

the head. Self-lifting pressure plate terminals save wiring time.

Industry-leading breadth of products

WITHSTANDS MANY CAUSTIC ENVIRONMENTS

A die-cast zinc head and aluminum body make the LSX suitable for indoor and

outdoor applications. A diaphragm seal between the head and body is designed

to provide an extra measure of protection. Switches remain functional when

exposed to many severe environments and caustic chemicals.

OPTIONAL SEALS

Standard seals are suitable for most applications, but optional fluorocarbon

or fluorosilicone seals are available for many harsh chemical, high or low

temperature environments.

DESIGNED TO CONTROL LOW-VOLTAGE DC APPLICATIONS

Hazardous area switches are available with a choice of silver or gold-plated

contacts to handle a variety of electrical load requirements from low energy to

power-duty control.

MICRO SWITCH™ Hazardous Area Limit Switches

MICRO SWITCH™ LSX SERIES OPERATING

SPECIAL OPTIONS

HEADS

HIGH TEMPERATURE/CHEMICAL RESISTANT

SWITCHES

SIDE ROTARY: Heads may be positioned in any one of four posi-

tions, 90° increments. All are momentary action except maintained

head (LSXN Series).

Completely ﬂuorocarbon (FC)-sealed switches have a full FC body

gasket covering the switch cavity. Rotary types have an extra

FC seal on the operating shaft, while plunger versions have FC

boot seals. They are designed for use in applications where the

environment includes ﬁre-resistant synthetic ﬂuids. In addition,

the FC-sealed switches may be used with such industrial ﬂuids

as Cellulube, Fyrquell, Houghto-Safe, Pydraul, and other special

cutting and hydraulic ﬂuids. The additional FC seals also promote

extended operating life for rotary-actuated LSX switches in applica-

tions where the temperatures are normally -12 °C to 121 °C [10 °F

to 250 °F].

LSXA - Standard: 60° minimum over-

travel, 15° maximum pretravel,

5° (single pole) and 7° (double pole) maxi-

mum differential travel.

LSXR - Low operating torque: 60° minimum overtravel, 15°

maximum pretravel, 0.19 Nm [1.7 in-lb] maximum operating

torque.

LSXN - Maintained contact: Maintained on counterclockwise

rotation and reset on clockwise rotation, and vice versa.

To order, insert the additional letters Y and C in the appropriate

places in the standard catalog listing, as shown below:

LSXP - Low differential: 68° minimum overtravel, 9° maximum

pretravel, 3° (single pole) and 4° (double pole) maximum differen-

tial travel.

LSXA3K

standard, side-rotary plug-in switch

LSXYAC3K

completely FC-sealed version of LSXA3K

LSXH - Low torque, low differential travel: 68° minimum

overtravel. Features low operating torque and narrow differential

travel.

LOW TEMPERATURE SWITCHES

All forms of LSX limit switches are also available in low-temperature

construction. Design features include ﬂuorosilicone diaphragm,

shaft seals, and external boot seal (where applicable).

LSXL - Sequence action: 48° minimum overtravel. Delayed

action between operation of two poles.

LSXM - Center neutral: 57° minimum overtravel. One pole

operates on the clockwise rotation, and the other pole on the

counterclockwise rotation.

To order, insert the additional letters Y and B in the appropriate

places in the standard catalog listing, as shown below:

LSXU - Low pretravel: 5° max. pretravel, 70° min. overtravel.

LSXA3K

standard, side-rotary plug-in switch

low-temperature version of LSXA3K

LSXYAB3K

TOP ROTARY: Available levers provide greater versatility. Heads

may be positioned in any one of four positions, 90° increments. All

are momentary action.

LSXB: With 100° minimum overtravel.

Various levers that ﬁt side rotary shafts may

be used on the top rotary shaft. Switch is

suitable for use when increased overtravel

is required.

LSX Series

MICRO SWITCH™ LSX SERIES OPERATING HEADS

TOP PLUNGERS: Available with 4,83 mm [0.19 in] minimum

overtravel. Top pin plungers are offered in pin plunger, an

adjustable plunger, and a roller plunger.

SIDE PLUNGERS: Made of non-sparking copper alloy. Available

with 4,83 mm [0.19 in] minimum overtravel. Side plungers are of-

fered in plain plunger, an adjustable pin plunger, and a

roller plunger.

LSXC - Top pin plunger: A copper alloy

plunger for in-line actuating motion. Oil-

tight seals on plunger and between the

operating head and housing are designed

to keep out coolant, dust, and chips.

Momentary action.

LSXE - Side pin plunger: A copper alloy

plunger for actuating motion inline with the

plunger travel. Actuating head may be ro-

tated in any of four positions, 90° apart. A

boot seal on the plunger and a gasket seal

between the head and housing is designed

to keep out coolant, dust, and chips. Mo-

mentary action.

LSXD - Top roller plunger: A copper

alloy roller plunger is adjustable to 90°

angles to accept cam or slide operation

from any of two directions. Boot seal on

the plunger. Momentary action.

LSXF - Side roller plunger: A copper

alloy roller plunger ﬁts close quarters under

cams and slides. The head may be rotated

in any of four positions, 90° apart. The

roller can be turned vertical or horizontal to

the switch. Boot seal on plunger. Momen-

tary action.

LSXV - Adjustable top pin plunger: A

copper alloy adjustable plunger is designed

to simplify the application and decreases

installation time. The operating points of

the switch can be adjusted from 65,66

mm to 72,0 mm [2.585 in to 2.535 in].

Seals are the same as the pin plunger.

Momentary action.

LSXW - Adjustable side pin plunger:

Has the same features of the side plain

plunger plus the means to adjust the oper-

ating points of the switch from 41 mm to

47,4 mm [1.615 in to 1.865 in]. Momentary

action.

WOBBLE LEVER ACTUATING HEADS: Heads come with

either a Delrin^®plastic rod or a copper alloy cat whisker. Any

movement of the lever (except pull) will actuate the switch.

LSXJ - Plastic rod:

Recommended where
