SUBMINIATURE SIZE
LIMIT SWITCHES
QL (AZ4) Micro
Limit Switches
High precision micro limit switches with excellent environment proofing
Quickly upgraded to limit switches with lamps by mounting an LED lamp socket
An exposed terminal type model com-
bined with a socket with cord for the
built-in LED lamp (sold separately) easily
become a limit switch with lamp.
Convenient for maintenance such as
operations checks.

FEATURES
1. Subminiature design
The size of the actual unit is approxi-
mately 1/10 in the case of the plunger
model and approximately 1/6.5 in the
case of the arm model, that of the verti-
cal type limit switch.
Large-scale miniaturization has been
achieved. Ideal for miniaturized machin-
ery designs or highly accurate miniatur-
ized machines.
Approx. 1/10
3. With appropriate O.T. range display
The arm model has a convenient appro-
priate O.T. range display for attachment
adjustment work. This should be set so
that the operations display board’s indi-
cated protrusion winds inside the protru-
sion on the axle receptor, permitting use
under optimum conditions.

2. A lamp can be easily added for
operations checks
4. Terminal uses both solder and tab
(#110)
5. O.P. accuracy of ±0.2 (O.P. repeated
accuracy initially ±0.03) achieved
Attachment accuracy improved greatly
The plunger model has achieved a high
O.P. repeated accuracy of within
0.03mm through the development of a
unique switch mechanism and a stan-
dard attachment surface on the upper
surface of the unit (a surface with no
slants.)
Also, through a unique mechanism that
permits adjustment of the O.P. in each
individual product at the time of assem-
bly, an O.P. accuracy of ±0.2mm
.008inch
can be safeguarded between
lots, so that almost no operating position
adjustment is required during either
attachment or replacement.
6. A subminiature limit switch with a
great stroke margin (O.T./T.T.)
The T.T. has been enlarged by using a
switching mechanism by coil spring for
QL.
7. Long life
The unit has a long mechanical life of
minimum 10
7
times and a long electrical
life of min. 3
10
5
times (5A, 250V AC
resistance load) by means of a silver
alloy contact with excellent solvent-proof
characteristics and a guaranteed wiping
operation that possesses two hinges and
switching method by coil spring.
8. A mechanism with excellent envi-
ronment proofing
• A protective construction equivalent to
IEC IP64
The actuator has an axle seal with spe-
cial packing, and the main case and ter-
minals have both a waterproof ring and
an epoxy-sealed mechanism. Also, the
entire mechanism is water-proof due to
the optional socket.
Socket with cord type... IP64 equivalent
• A sturdy, shockproof construction
The body uses die-cast zinc, and the
actuator uses stainless steel. Moreover,
shock absorbers have been added to
lessen the shock during plunger release.
TYPICAL APPLICATIONS
Any application where compactness,
density, and robustness, such as sub-
miniaturized machines and plant machin-
ery, is required.

screws, grasp the terminal cover and pull
it away from the switch body.
2) Remove the fastening screw from the
terminal block. (Remove with the 3 termi-
nal receptacle.)
Pull away from the body.
Turn counterclockwise.
8) After the terminals have been properly
crimped in the terminal body, insert the
body into the terminal case. (When
inserting the body, be careful not to block
the hole for the fastening screw with the
wires.)
2. Socket with cord (including socket
with lamp)
1) Apply the rubber packing over the ter-
minals, then insert the socket with cord
into the switch body.

3) Loosen the hexagonal nut and
remove the rubber bushing and washer
from the inside.
Turn counterclockwise.
9) Temporarily screw in the fastening
screw through the terminal body, then
insert the washer and rubber bushing
into the cord opening of L socket.
Tighten it with a wrench or pliers.
2) Screw the socket fastening screw into
the switch body and tighten it.
4) Select cord from applicable wire table.
5) Decide which direction the cord outlet
is to face and strip the sheath according-
ly. (See page 43.)

Mounting
The QL micro limit switch is manufac-
tured with a very small variation in the
distance between the datum plane and
the operating point. When the operating
point has been accurately established
and the mounting position clearly deter-
mined, two M4 bolts should be used
securely fastening the switch.
Operating position
(O.P.)
11) Tighten the fastening screw into the
switch body.
7) After stripping the cord sheath, insert
the corresponding wires into the grooves
of the terminal body up to the wire stop,
then crimp the terminal receptacle over
the wires with a pair of pliers.
