SPECIAL CONDITIONS FOR SAFE USE
Honeywell explosion-proof switches are designed specifically
for use in hazardous location applications. The BX enclosure is
sealed for protection against corrosion, water, dust and oil as
defined in NEMA 1, 3, 4, 4X, 6, 13, and IP67 (per IEC60529).
The temperature rating for these products depends upon the
seal material used. Products using a fluorosilicone seal have
a rating of -40 °C [-40 °F] to 70 °C [158 °F]. Products using a
fluorocarbon seal have a rating of -12 °C [10 °F] to 70 °C [158
°F]. MICRO SWITCH™ BX switches are rated according to the
electrical ratings detailed in Table 1.

The maximum construction gap (ic) is less than that required
by Table 2 of EN/IEC60079-1, clause 5.2.2 as detailed below in
Table 3.
The equipment has a non-conducting coating and may gener-
ate an ignition-capable level of electrostatic charges under
certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be sub-
jected to external conditions (such as high pressure steam)
that might cause a build up of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
should be done with a damp cloth.

During installation, BX Series limit switches should not be
subjected to a corrosive atmosphere that could corrupt the
enclosure, thereby avoiding immediate or future corrosion of
the switchs enclosure.
WARNING
Do not replace any switch components with those from
another switch or replacement part without consulting
Honeywell technical support.
WARNING
During the switchs installation, use, and maintenance,
observe the following standards: GB15577; GB/T3836.13;
GB/T3836.15; GB/T3836.16; and GB50257.
WARNING
The equipment has a non-conducting coating and may
generate an ignition-capable level of electrostatic charges
under certain extreme conditions. The user should ensure
that the equipment is not installed in a location where it may
be subjected to external conditions (such as high pressure
steam) which might cause a build up of electrostatic
charges on non-conducting surfaces. Additionally, cleaning
of the equipment should be done with a damp cloth.
WARNING
Any cable glands used with this product shall be provided
with protection d for hazardous location category IIC with
certificate, according to TP TC 012/2011.

MICRO SWITCH EXPLOSION-PROOF LIMIT SWITCH
BX SERIES
Issue 11
50083427
The BX is ideal for outdoor use or in adverse environments
where a combination of explosion-proof plus sealing require-
ments are needed. To comply with explosion proof require-
ments the BX has flame paths within the housing, which cool
exploding gases below the ignition temperature before they
reach explosive gases surrounding the housing. Flame paths
on the BX are (1) an extended plunger between the switch cav-
ity and head and (2) the cover-housing threads on the front of
the switch.
MOUNT, ADJUST, WIRE MOUNTING
Note mounting dimension drawings for hole locations (Fig.
9, page 3). The BX is directly interchangeable with the LSX
explosion-proof limit switches: Adapter plate is not required.
ADJUSTING INSTRUCTIONS
To give flexibility in application, the user can perform the ad-
justments described below in any order before wiring the unit.
ACTUATOR HEAD
The actuator head may be positioned in any of four directions.
1. Loosen the four captive head screws.
2. Place head in the desired position.
3. Securely tighten the four screws to 1,4 Nm to 1,8 Nm [12
in-lb to 16 in-lb] (Figure 1).
REVERSING THE ROLLER LEVER
Except for the offset roller levers, the roller arm may be reversed
to face the roller to the inside or outside of the arm.
Figure 1. Figure 2.
4 × 90° 360°
Figure 3.
POSITIONING LEVER
The lever on rotary actuated units is adjustable to any position
through 360° around the shaft.
1. Loosen the cap screw with 9/64-inch hexagon key wrench.
2. Move lever to desired position.
3. Securely tighten screw until teller tab can no longer be
moved by hand.
4. Tighten screw another 1/8 to 1/4 turn to assure lever is
tight on the shaft (Fig. 2).
A 9/64-inch hex key wrench is provided in the adjusting tool set
LSZ4005.
ADJUSTABLE LENGTH LEVERS
To adjust the length of the adjustable length levers, a 9/64-
inch hexagon key wrench is required. A 9/64-inch key wrench is
provided in the adjusting tool set LSZ4005.
TOP ROLLER PLUNGER
Position the top roller plunger in the desired roller plane, by
adjusting the head as explained under actuator head.
SIDE ROLLER PLUNGER
Grasp the plunger with a pair of pliers and rotate to the desired
horizontal or vertical position (Fig. 3).
CHANGING DIRECTION OF ACTUATION
SIDE ROTARY
Catalog listings with the first three letters BXA, BXH, BXL, BXP,
and BXR may be adjusted to operate clockwise, counter-clock-
wise or both. Catalog listings BXM (center neutral) and BXN
(maintained) operate in both directions but cannot be changed.
To change the actuation direction for the BXA, BXH, BXL, BXP,
and BXR, follow these steps:
1. Loosen the head screws and remove the head from the
switch housing.
2. On the bottom of the head, insert a screwdriver in the slot
provided (Fig. 4) and lift open the hinged cover.
3. Referring to Fig. 5, slide the cam all the way back, so cam is
free to rotate on the shaft.
4. Using a screwdriver or similar tool, rotate the cam to the
desired actuating position (Fig. 6).
5. Slide the cam all the way forward to its original position,
and close the hinged cover.
6. Replace the operating head on the switch housing and
securely tighten the head screws to 1,4 Nm to 1,8 Nm [12
in-lb to 16 in-lb].

TOP ROTARY
Follow these steps to change the operating direction of the BXB
type switch:
1. Loosen the head screws and remove head from the switch
housing.
2. From the bottom of the head, grasp the end of the pin
plunger (Figure 7) and remove the pin. It may be necessary
to rotate the actuating shaft to expose the end of the pin
plunger.
3. Referring to Figure 8, select the correct pin plunger posi-
tion for the desired direction of actuation.
4. Insert the pin plunger in the position providing the desired
direction of actuation.
5. Replace the operating head on the switch housing and
securely tighten the head screws to 1,4 Nm to 1,8 Nm [12
in-lb to 16 in-lb].

qualities.
WIRING INSTRUCTIONS
1. Unscrew cover to expose the switching element for wiring
or replacement. To aid in cover removal, a screwdriver or
bar may be used on the wrenching lugs. Use up to size
#12 AWG solid or stranded wire to connect to the pres-
sure type connector terminals. Stripped wire ends or any
spade and ring connector that will fit the terminals may be
used. Spades may be up to 7,9 mm [0.312 in] wide, rings
up to 7,9 mm [0.312 in] diameter. With spade or ring type
connections preinsulated connectors or heat-shrinkable
tubing should be used to provide insulation between ter-
minals. Conduit size, electrical ratings and circuit diagram
are shown on the nameplate. Wire the double pole units by
connecting lead wires to the terminals nearest the conduit
opening first. An internal grounding screw is located on the
right side; an external grounding screw is located on the
upper left side. Torque all terminal screws and grounding
screws to 1 Nm to 1,8 Nm [9 in-lb to 16 in-lb]. Reassemble
cover and torque to 10 Nm [90 in-lb].
2. Put cover locking clamp on circular cover and tighten the
flat head cross recessed screw to 1,5 Nm to 1,8 Nm
[13.27 in-lb to 16 in-lb]. (See Figures 9 and 10)
3. The internal grounding terminal must be used for the
equipment grounding connection, and the external termi-
nal is for supplementary bonding connection where local
codes or authorities permit or require such connections.
