Photoelectric Switches
IDEC’s original spring-up screw
terminal block saves wiring time
Washdown IP67 Environment
Four Sensing Methods
Time Delay
Various Mounting Hole Layouts
Universal Voltage Power Supply
Ideal for use in a wet enviroment such as bottling and food
processing lines.
Four operation modes to choose from: one shot, ON delay,
OFF delay, and normal modes.
Time ranges can be set from 0.1 to 5 seconds.
Universal voltage types operate on 24 to 240V AC and
12 to 240V DC. DC power types operate on 12 to 24V DC.
Mounting hole centers are selectable from 40, 50 to 55 mm.
Long distance detection. Offers sensing range of up to 50m.
Sensing range up to 2m. Not affected by background.
Sensing range up to 7m. Easily detects mirrored surfaces.
Sensing range up to 1m. Detects objects that reflect light,
even transparent objects.
Background suppresion
Polarized-retroreflective
Suitable for interference prevention,
enabling close mounting of through
beam type photoelectric switches,
and for detecting small objects.
Available in slit widths of 1 mm and
3 mm. Attaching 3-mm wide slits to
both the projector and receiver
restricts the sensing range by 50%.
(sensing distance: 15m)
Can be easily attached even after
installing the SA1U.
IDEC’s unique spring-up screw
terminal block∗ is used
.
∗The screw is normally in the lifted position,
ready for wiring. No need to loosen or
remove screws, improving work
efficiency. Screws are held
captive.

Through Beam Type (Optional)
Operation status can be
easily recognized by LEDs
Recognizable from different
directions. The front side is
visible from a distance.
Sensitivity of through-beam
types can easily be
adjusted.
Close Mounting
(except through-beam)
Interference prevention enables close mounting
of two SA1U photoelectric switches in limited spaces.
Diffuse-reflective
Through-beam
Suitable for detecting
the object.

is not detected.
Ideal for use in large
facilities such as
automatic parking lots.
