6. Installation
Installing the Photoelectric Switch
•
Do not install the SA1E photoelectric switches in an area where the switches
are subject to the following conditions, otherwise mal function and damage
may be caused.
Inductive devices or heat source
Extreme vibration or shock
Large amount of dust
Toxic gases
Water, oil, chemicals
Outdoor
•
Make sure to prevent sunlight, fluorescent light, and especially the fluores-
cent light of inverters from entering the receiver of the pho toelectric switch
directly. Keep the through-beam type receiver away from intense extraneous
light.
•
Interference prevention allows two SA1E switches to be mounted in close
proximity. However, the through-beam type is not equipped with interference
prevention. Maintain appropriate dis tance between the switches referring to
the lateral displacement characteristics on pages 179, 180, and 181.
•
Because the SA1E photoelectric switches are IP67 waterproof, the SA1E can
be exposed to water. However, wipe water drops and smears from the lens
and slit using a soft cloth to make sure of the best detecting performance.
•
Polycarbonate or acrylic resins are used for optical elements. Do not use
ammonia or caustic soda for cleaning, otherwise optical elements will be dis-
solved. To remove dust and moisture build-up, use soft dry cloth.
•
Tighten the mounting screws (M3) to a torque of 0.5 N·m. Do not tighten the
mounting screws excessively or hit the switch with a hammer, otherwise the
protection degree cannot be maintained.
Installing the Reflector
•
Use M4 mounting screws for the IAC-R5 reflector and M5 mount ing screws
for the IAC-R6 reflector. Tighten the mounting screws to a tightening torque of
0.5 N·m maximum. Mounting screws are not supplied with the switch.
•
Use the M3 self-tapping screw, flat washer, and spring washer to tighten the
IAC-R7 reflector to a torque of 0.5 to 0.6 N·m.
•
While optional reflector mounting bracket IAC-L2 is not supplied with mount-
ing screws or nuts, the IAC-L3 and IAC-L5 are supplied with mounting screws
for mounting the reflector on the bracket.
•
Reflector IAC-RS1 and IAC-RS2 can be installed directly on a flat surface using
the adhesive tape attached to the back of the reflec tor. Before attaching the
reflector, clean the board surface to ensure secure attachment.
Installing the air blower mounting block SA9Z-A02
•
When installing the SA9Z-A02 on the SA1E photoelectric switch, use the
attached M3 × 20 mounting screws and tighten to a torque of 0.5 N·m
maximum.
•
Do not use the mounting screw (M3 × 12) supplied with the mount ing bracket
(SA9Z-K01) to mount the SA1E photoelectric switches.
•
The SA9Z-A02 cannot be used with the through-beam slits (SA9Z-S06 to 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 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.
