A compact and accurate vertical limit switch. Type with a lamp which makes main-

tenance convenient; either a neon AC powered lamp or an LED DC powered lamp.

FEATURES

1. Compact design approximately 1/3

of the AZ5 limit switches

2. Au-clad contacts that can even use

low level circuit and little chattering

and bouncing

The built-in switch has Au-clad contacts

with excellent contact reliability and uses

a crossbar contact method, and more-

over, has a dual cutoff circuit (1 Form A

1 Form B contact) with little chattering

and bouncing due to computer-operated

analysis.

3. Easy wiring with full-open terminals

When the cover is removed, the termi-

nals are open as far as the flank, so the

necessity to insert your fingers into a

case to complete the wiring has been

removed. Moreover, the wiring space is

large despite the compact size, and the

terminals are spread in a tiered array, so

that wiring work can be completed very

easily.

The cable can either be screwed in

directly, or can use U-shaped and circu-

lar pressure terminals.

4. Mounting are possible to both front

and back

5. Type with a lamp that can be used

with a wide range of voltages

• With neon lamp

Compatible with: 100 and 200V AC ;

Even at 100V AC, sufficient luminosity is

achieved through the diamond-cut lens.

Also with a long lifespan of more than 20

thousand hours.

• With LED lamp

Covers 6 to 48V DC and comes in three

types, 6V DC , 12V DC , 24 to 48V DC

Uses two highly luminescent LEDs and

in addition, sufficient luminosity is

achieved through the diamond-cut lens.

6. Lamp connection can be either

spring type or lead wire type

• Spring type (wiring unnecessary)

(With neon or LED lamp type)

Wiring is unnecessary because the lamp

is directly connected to the terminals. By

simply changing the direction of the lamp

holder attachment, it is possible to dis-

play both lights during inoperability and

during operation (however, if both N.O.

and N.C. loads are connected, only the

inoperability lamp can be displayed.)

Construction permits lamp attach-

ment method to be changed.

• Lead wiring type <Current leakage: 0>

(LED lamp type only)

Because the wiring can be made parallel

to the load, current leakage from the

lamp can be reduced to 0. Even with a

slight leak, the electronic circuit incurring

the leak can be used safely.

7. Dust-proof, waterproof, oil resistant

construction

The main unit and the cover are sealed

with rubber packing, and the cord runner

is doubly sealed by the cord vent. The

actuator is sealed by both a rubber cap

and an O ring in all models. Also, the

lens and cover are formed simultaneous-

ly with the lamp type, and moreover, a

nameplate is affixed to the upper sur-

face, thereby improving the already

excellent waterproof capabilities.

(Note: Applications directly involving the

cord entrance and the locations which

are always wet and oily, or submersion

in water or oil, cannot be used.)

TYPICAL APPLICATIONS

Ideal for general plant facilities such as

engineering machinery, conveyer

machinery, and assembly lines

LED lamp type is also compatible with

low-voltage DC control circuits such as in

PCs and computers.
