QL (AZ4) Micro
Limit Switches
SUBMINIATURE SIZE
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.
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

7. Long life
LED lamp
The unit has a long mechanical life of
minimum 107 times and a long electrical
life of min. 3 ꢀ 105 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
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.

FEATURES
1. Subminiature design
• A protective construction equivalent to
O.T. exceeded
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.
IEC IP64
Appropriate range
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.

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.)
• 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.

Notes) 1. Cadmium free contact types are available on a custom-made basis. Please add an “F” to the end of the part number when ordering.
2. *L socket type or socket with cord type is combination of;
L socket type = Exposed terminal type + L socket, Socket with cord type = Exposed terminal type + Socket with cord type (cord length: 1m)
3. UL recognized, CSA certified type available. When ordering, add suffix 9 to part No..
(For the socket with cord type, only UL recognized type available with suffix 9 to the part No.)
