Various Mounting Hole Layouts Mounting hole centers are selectable from 40, 50 to 55 mm.
IDEC’s original spring-up screw terminal block saves wiring time
Object
Spring-Up Screw Terminal Block 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.
Adhesive Vertical Slit for Through Beam Type (Optional) 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.

SA1U Photoelectric Switches Instructions Notes
Wiring
• When installing photoelectric switches, take into consideration the reflecting light from the floor or walls as it may affect sensing of through-beam and background suppression models. • Make sure to prevent sunlight, fluorescent light, and fluorescent light of inverters from entering the receiver of the photoelectric switch directly. Keep the through-beam model receiver away from intense extraneous light. • When installing SA1U photoelectric switches, do not tighten the mounting screws excessively or hit the switch with a hammer, otherwise the protection degree cannot be maintained. • Make sure that the supply voltage is within the rated values. • When using a switching regulator, be sure to ground the FG (frame ground) terminal. • To suppress a transient state at start-up, a circuit to turn off the output is installed (universal voltage type: 50 ms, DC power type: 100 ms). The timer will start after resetting the off output. • To meet European Union Low Voltage Directives, install an EN approved fuse on the outside of the power terminal or output terminal of the universal voltage type SA1U photoelectric switches. • Attach the cover properly to maintain waterproof characteristics. • Interference prevention allows two SA1U photoelectric switches to be mounted in close proximity. However, the through-beam model is not equipped with interference prevention. Maintain appropriate distance between the switches referring to the lateral displacement characteristics on page 8. • Optional slits (SA9Z-S15, SA9Z-S16) for through-beam models are available for inteference prevention and to detect small objects. When using the slits, take the following into consideration: 1) Wipe the lens surface of the switch with a soft dry cloth before sticking the adhesive tape side of the slit to the lens surface. 2) When attaching the slit, align the ends of the slit with the ends of the lens correctly. 3) The slit cannot be reused once it is peeled off because the adhesive power is lost. 4) Wipe off water drops as water on the slit will change detection characteristcs. • When mounting the reflector, do not tighten the mounting screws excessively, otherwise the screw hole of the reflector may be damaged. • Use M4 mounting screws for the IAC-R5 and IAC-R8 reflectors and M3 mounting screws for the IAC-R6 reflector. Tighten the mounting screws to a tightening torque of 0.5 N·m maximum. • 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 mounting screws or nuts, the IAC-L3 and IAC-L5 are supplied with mounting screws for mounting the reflector on the bracket. • IAC-RS1 and IAC-RS2 reflectors can be installed directly on a flat surface using the adhesive tape attached to the back of the reflector. Before attaching the reflector, clean the surface to ensure secure attachment. • Polycarbonate or acrylic resins are used for optical elements. Do not use ammonia or caustic soda for cleaning, otherwise optical elements will dissolve. To remove dust and moisture build-up, use soft dry cloth. • Do not install the SA1U photoelectric switches in areas where the switches are subject to water, oil, and chemicals.

• Connect the cables to the correct terminal number. Connect the lower terminal screws first. • Attach the cover and secure with the set screw. *To maintain waterproof and dustproof characteristics, use cabtyre cables (do not use soft cables as it may fall out) with ø8 to ø10 mm diameter. Install the attached gland gasket and washer and tighten the gland securely. For the small gland gasket, use a cable with ø8 to ø10 mm diameter. For the large gland gasket, use a cable with ø9 to ø10 mm diameter. The cable sheath should be 10 mm approx. Make sure that the gland washer fits in the groove of the gasket. • When wiring, make sure that the power is turned off. • Incorrect wiring may cause damage to the internal circuit. • Avoid parallel wiring with high-voltage or power lines (especially inverters) in the same conduit, otherwise noise may cause malfunction and damage. • When wiring is long or may be affected by power lines, use a separate conduit for wiring. • Use a cable of 0.3 mm2 minimum core wires. The cable can be extended up to 100m. For DC power types, voltage drop due to resistance of the cable lead wire should be taken into consideration. • When using crimp terminals, make sure that the terminals do not come into contact with adjacent terminals. For correct installation, see the figure below. Correct

Adjustment of Sensing Range for Background Suppression
Optical Axis Alignment (Light ON)
When adjusting the sensing range, follow the instruction below.
(1) Through-Beam Model Fasten the receiver temporarily. Place the projector facing the receiver. Move the projector up, down, right and left to find the range where the operation LED turns on. Fasten the projector in the middle of the range. Next, move the receiver up, down, right, and left in the same manner and fasten in the middle of the range where the operation LED turns on. Make sure that stable LED turns on at stable incident and stable interruption. 2

Move the SA1U photoelectric switch up, down, right, and left to find the range where the operation LED turns on. Fasten the switch in the middle of the range. Polarized retroreflective model can be installed also by finding the position where the reflection of projected red light is most intense, while observing the reflection on the reflector from behind the switch. Make sure that stable LED turns on at stable incident and stable interruption.
(3) Diffuse-Reflective Model Place the SA1U photoelectric switch where the switch can detect an object. Move the switch up, down, right, and left to find the range where the operation LED tuns on. Fasten the switch in the middle of the range. Make sure that stable LED turns on at stable incident and stable interruption.
