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 combined 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 approximately 1/10 in the case of the plunger
model and approximately 1/6.5 in the
case of the arm model, that of the vertical type limit switch.
Large-scale miniaturization has been
achieved. Ideal for miniaturized machinery designs or highly accurate miniaturized machines.

2. A lamp can be easily added for
operations checks

3. With appropriate O.T. range display
The arm model has a convenient appropriate O.T. range display for attachment
adjustment work. This should be set so
that the operations display board’s indicated protrusion winds inside the protrusion on the axle receptor, permitting use
under optimum conditions.

4. Terminal uses both solder and tab

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 standard 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 107 times and a long electrical
life of min. 3 ‫ 501 ן‬times (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 environment proofing
• A protective construction equivalent to
IEC IP64
The actuator has an axle seal with special packing, and the main case and terminals 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 subminiaturized machines and plant machinery, is required.
