VL (AZ8) Mini
Limit Switches
COMPACT SIZE
LIMIT SWITCHES
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.
The cable can either be screwed in
directly, or can use U-shaped and circu-
lar pressure terminals.
6. Lamp connection can be either
spring type or lead wire type
• Spring type (wiring unnecessary)
(With neon or LED lamp type)
Inner construction
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.)

FEATURES
1. Compact design approximately 1/3
of the AZ5 limit switches
M4 attachment bolt
• 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.

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 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.)

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.
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.
