Meaning of Alert Symbols
The following alert symbols are used in this manual.

Indicates mandatory actions.

WARNING The machine may start operating and may result in serious injury or death. Do not put the actuator close to the switch when the door is opened.
Also, make sure to install D40A to minimize defeat possibilities. For required measures, refer to ISO14119 and other relevant standards and regulations.

Precautions for Safe Use

(1) Disconnect G9SX-NS from the power supply when wiring D40A. Devices connected to G9SX-NS may operate unexpectedly.
(2) Do not operate the D40A with flammable or explosive gas.
(3) Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of D40A before using the system in which D40A is incorporated.
(4) Auxiliary monitoring output is NOT safety output. Do not use auxiliary monitoring output as any safety output. Such incorrect use causes loss of safety function of D40A and its relevant system.
(5) After installation of D40A, qualified personnel should confirm the installation, and should conduct test operations and maintenance. The qualified personnel should be qualified and authorized to secure the safety on each phase of design, installation, running, maintenance, and disposal of the system.
(6) A person in charge, who is familiar with the machine in which D40A is to be installed, should conduct and verify the installation.
(7) Be sure to inspect D40A daily and every 6 months. Otherwise, serious injury may possibly occur due to the system malfunction.
(8) Do not dismantle, repair, or modify D40A. Doing so may lead to the loss of its safety functions.
(9) Use only appropriate components or devices complying with relevant safety standards corresponding to the required level of safety category. Conformity to requirements of the safety category is determined as an entire system. It is recommended to consult a certification body regarding the assessment of conformity to the required safety level.

Precautions for Correct Use

(1) D40A must be used with the designated actuator (D40A-1C or -A1) and designated controller type G9SX-NS. Before using the D40A with any other OMRON Safety Controller, check applicability in the Instruction Manual for the other Controller.
(2) Handle with care Does not drop D40A to the ground or expose to excessive vibration or mechanical shocks. D40A may be damaged and may not function properly.
(3) Conditions of storage and usage Do not store or use the D40A under the following conditions. D40A may be damaged and may not function properly.

1. Indirect sunlight
2. At ambient temperatures out of the range of –10 to 55°C
3. At relative humidity out of the range of 25% to 85% or under such as temperature change that causes condensation.
4. In corrosive or combustible gases
5. With vibration or mechanical shocks out of the rated values.
6. Under splashing of oil or chemicals
7. In the atmosphere containing dust, saline, or metal powder.
8. Where steel scrap or metal powder may fall directly to D40A.
   (4) Use cables with a length less than 100m totally to connect multiple D40A switches. The supply voltage to D40A may decrease by the voltage drop depending on the cable or the wiring configuration. Check the power-supply voltage is in the rated range.

(5) Disconnect G9SX-NS from the power supply when replacing D40A. Devices connected to G9SX-NS may operate unexpectedly.
(6) Adhesion of solvents such as alcohol, thinner, trichloroethane, or gasoline on the product should be avoided. Such solvents make the marking on D40A illegible and cause deterioration of parts.
(7) Do not use D40A in the magnetic field of 1.5mT or more. D40A may not function properly.
(8) Do not use the D40A in the water or continuous water exposure environment. Water may lead into the D40A.
(9) Do not use the switch or actuator as a stopper. Protect the switch and the actuator by setting up the stopper. Separate the switch and the actuator to a distance of 1mm or more.
(10) Install the D40A actuator and switch at an appropriate distance so that it does not create a gap accessible to the hazard.

(11) Where two or more switches are mounted adjacent, they should be no closer than 25mm.

(12) Check that the machine is stopped whenever the interlocked guard door is open.

(13) Do not mount the switch and actuator on magnetic materials, otherwise, it may affect the operating distance. Refer to the chart below for the estimated influence.

(14) Tighten each screw with specified torque by using an M4 screw and washer for the installation of the switch and actuator. After installation and commissioning, the actuator and switch fixing screws should be coated with tamper-proof varnish or a similar compound. Using anaerobic locking compounds can have a detrimental effect on the plastic switch case if the compounds contact the switch case.

(15) Wiring
1. Use the following to wire to G9SX-NS
-Solid wire: 0.2 to 2.5mm2 AWG24 to AWG12
-Stranded wire: 0.2 to 2.5mm2 AW G22 to AW G12
2. When u cilia try output is not used, cut off the wiring and protect by taping so that it does not contact other terminals.
3. When you use an additional cable of 20m or longer, use a multiconductor cable to group the white, black, brown, and blue lines together.
(16) Handle cables with care:

1. For bending cables, it is recommended to bend them with a radius of bend no less than six times the cable outer diameter.
2. Do not apply a tensile strength of 50N or greater to the cables.
   (17) This is a class A product. In residential areas, it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.
   (18) If there is any machine that has a large surge current(e.g., a motor) near D40A, connect a surge absorber to D40A between the blue and the other lines (white, black, brown, and yellow), respectively.
   The suggested surge absorber’s specification is as follows: (Per IEC61000-4-5(surge immunity)) -Breakdown voltage: 27-33V

Detection Ranges (Engineering data)

Note1. The operating distance is the distance between the switch and actuator sensing surfaces.
Note2. The graph indicates shifting to X or Z direction from the following condition that the switch and actuator target marks are on the same axis and the sensing surfaces are exactly parallel condition. Dashed lines indicate reference values for maximum and minimum operating distance at ambient temperature +23°C. The solid line indicates reference values of the maximum and minimum operating distances.
