PRODUCT TYPE

1. Switch body

High precision micro limit switches with excellent environment proofing

Quickly upgraded to limit switches with lamps by mounting an LED lamp socket

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.

2. A lamp can be easily added for

operations checks

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.

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.

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 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

• 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.

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.)
