which, if not avoided, will result in minor or
moderate injury, or may result in serious
WARNING
injury or death.
Additionally there may be significant property
damage.
Alert Statements
WARNING
Use only appropriate components or devices complying
with relevant safety standards corresponding to the
required performance level and category. Conformity to
requirements of the performance level category must be
determined as an entire system. It is recommended to
consult a certification body regarding assessment of
conformity to the required safety level.
Serious injury may occur in an accident. Make sure to use
the dedicated actuator D40A-A2, and install the switch
and actuator at an appropriate distance so that they do
not create a gap that provides access to the hazard.
Available Not available
Serious injury may occur in an accident. When complying
with safety standards, install the product in accordance
with ISO/EN ISO 14119 with due consideration of the risk
of the operator deactivating it.
Auxiliary output is NOT a safety output. Do not use the
Auxiliary output individually for any safety function. Such
incorrect use causes loss of the safety function of the
product and its relevant systems.
Serious injury may possibly occur in an accident.
Do not put the actuator or magnet close to the switch
when the door is opened.
Be sure to inspect the product daily and every 6 months.
Otherwise, serious injury may possibly occur due to the
system malfunction.
Precautions for Safe Use
(1) Dispose of the product in accordance with the laws set by each
country.
(2) Wire the input and output terminals correctly and verify the
correct operation of the product before using the system in
which the product is incorporated. Incorrect wiring may lead to
loss of the safety function.
(3) After the installation of the product, responsible personnel must
ensure that the installation, inspection, and maintenance are
carried out correctly. These personnel must be qualified and
authorized to ensure safety throughout each phase of design,
installation, running, maintenance, and disposal of the system.
(4) Tighten each screw with specified torque by using M4 screws
with a screw head diameter of up to 7mm or less for the
installation of the switch and actuator. After installation and
commissioning, the fixing screws for the switch and actuator
should be coated with tamper-proof varnish or a similar
compound to prevent loosening. Using anaerobic locking
compounds can damage the plastic case of each switch and
actuator if the compounds come into contact with the case.
(5) Serious injury may occur in an accident. Do not apply DC
voltages exceeding the rated voltages, nor any AC voltages to
the product.
Precautions for Correct Use
(1) The contents of Precautions for Safe Use: Paragraph 16 Series
Connection, Section 5. Connection Example, and Troubleshoot-
ing in this instruction manual are based on the assumption that
the product will be used in combination with the G9SX-NS
series. Refer to the D40A-2 data sheet (Cat. No. F133) for use
in combination with other OMRON safety controllers.
(2) Do not drop the product to the ground or expose to vibration or
mechanical shocks out of the rated values. Doing so may
damage the product and cause failure.
(3) Do not store or installation the product in the following places.
Doing so may result in product failure, or incorrect operation.
1) Places subject to direct sunlight
2) Operation in the range exceeding -25°C to 70°C
Storage at temperatures exceeding -25°C to 75°C
3) Operation in the range of relative humidity exceeding 25% to
85%
Storage at relative humidity exceeding 25% to 95%
Places subject to condensation due to sudden temperature
changes
4) Places subject to corrosive or flammable gases
5) Places subject to vibration or mechanical shocks exceeding
the rated values to the product
6) Operation in locations subject to exposure to oil, or chemicals
Storage in locations subject to exposure to water, oil, or
chemicals
7) Places subject to dust, salt, or iron particles
8) Places subject to iron cuttings or particles, etc. are directly

(5) Wiring
1. Use the following wire sizes for wiring.
-Stranded wire: 0.2 to 2.5 mm AWG24 to AWG12
2
-Solid wire: 0.2 to 2.5 mm 2 AWG24 to AWG12
2. When not using the auxiliary output, cut and insulate the
unused wires to prevent contact with other terminals.
3. If laying an additional cable of 20 m or longer, bundle the
white, black, brown and blue lines together.
(6) Do not use the product as a stopper. Keep the distance
between switch and actuator at least 1 mm.
(7) Handling the Cables:
1) When bending cables for wiring, the bending radius shall be
6 times or more than the cable outer diameter.
2) Do not apply a tensile strength of 50 N or greater to the cables.
(8) When two or more Switches are mounted side-by-side, they
must be no closer than the following distance.
25 mm*
25 mm*
* When mounting side-by-side with a D40Z Switch: 50 mm min.
(9) Do not use the product at an altitude of 2,000 m or higher.
(10) The degree of protection does not guarantee performance in
environments with continuous water exposure. Do not use the
product in water. Doing so may lead to water entered into the
product.
Conditions for the degree of protection
- Temperature range: 15 to 35°C, Humidity: 25 to 75%,
Atmospheric pressure: 86 to 106 kpa
(11) Never disassemble, repair, or modify the product. Doing so may

Inspection & Maintenance
 Daily inspection
Check every guard door to see that machine stops when guard
door is opened.
 Periodic inspection
In addition to daily inspection, be sure to conduct inspections
every 6 months.
1. Isolate all power.
2. Check the switch and actuator for proper alignment.
3. Check terminals for proper connections.
4. Check wiring for signs of damage.
5. Before resuming normal machine operation, check every guard
door to see that machine stops when the guard door is opened.
Based on ISO 14119, if the system requires a hands-on functional
test, also consider the following inspection frequencies:
· SIL3/ PL e at least once a month
· SIL2/ PL d at least once a year
