SA1E-L Miniature Laser Photoelectric Switches (Built-in Amplifier)
Installing the air blower mounting block SA9Z-A02
When installing the SA9Z-A02 on the SA1E-L photoelectric •
switch, use the attached M3 mounting screws and tighten to a
torque of 0.4 to 0.5 N·m maximum.
Mounting bracket is not supplied with SA9Z-A02 and must be •
ordered separately. SA9Z-K01 mounting bracket can be used with
SA9Z-A02. When installing the SA9Z-K01 mounting bracket on
SA9Z-A02 air blower mounting block, use the M3 × 20 mounting
screws supplied with SA9Z-A02. Do not use the mounting screws
(M3 × 12) supplied with SA9Z-K01.
The SA9Z-A02 cannot be used with the through-beam slits •
(SA9Z-S12, SA9Z-S13, and SA9Z-S14).
The air tube fitting (M5) can be installed to either the top or side. •
The air tube is not supplied.
Close the unused port using the supplied air supply port plugging •
screw (M5 × 6) and gasket to a tightening torque of 1 to 2 N·m
maximum. The recommended air pressure is 0.1 to 0.3 MPa.
Installing the background suppression (BGS) type
This sensor can detect objects correctly when the sensor head is •
installed perpendicular to the moving object. Install the sensor
head as shown below to minimize sensing errors.
If the SA1E-L is used in a place subject to large variations in the •
ambient temperature, the characteristics may change depending
on the target object. Be sure to check the operation under the
actual operating conditions.
Polarized retroreflective: when the sensing objects have mirror •
surface, the reflected light from the mirror surface might cause
false detection. Make sure that the reflected light does not enter
the receiver.

Using a laser product
The SA1E-L photoelectric switches radiate a visible laser beam. •
Do not look directly at laser beam. Also, do not look at the laser
beam reflected by a mirror surface.
IEC 60825-1 (Safety of laser products) sets safety standards of •
laser products. The SA1E-L photoelectric switches are classified
as Class 1 product.
The SA1E-L photoelectric switches comply with 21 CFR 1040.10 •
and 21 CFR 1040.11 according to Laser Notice No. 50, dated
June 24, 2007, issued by the CDRH (Center for Devices and Ra-
diological Health) under the FDA (Food and Drug Administration).
Labels •
According to IEC 60825-1 and FDA regulations, the SA1E-L has
the warning and certification/identification labels as shown below.
When installing the SA1E-L on a system/equipment used in the
United States, ensure that the labels are attached to the SA1E-L.
