Compact Non-Contact Door Switch
INSTRUCTION MANUAL
Thank you for purchasing D40A Compact Non-contact
Door Switch. Please read and understand this manual
before using the products. Keep this manual ready to
use whenever needed. Only qualified person trained
in professional electrical technique should handle
D40A. Please consult your OMRON representative if
you have any questions or comments. Make sure that
information written in this document are delivered to
the final user of the product.
The D40A non-contact door switch provides a
safety-related interruption at a specified proximity
position of its actuator through a safety controller.
Type D40A
English
2139497-6E
Machine may start operating and may result 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.
Safety Precautions
Meanings of Signal Words
The following signal words are used in this manual.
Alert Statements
WARNING
WARNING
Indicates a potentially hazardous
situation which, if not avoided, will
result in minor or moderate injury, or
may result in serious injury or death.
Additionally there may be significant
property damage.
(1)
Disconnect G9SX-NS from 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 phases of design,
installation, running, maintenance and disposal of system.
(6)
A person in charge, who is familiar to 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
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 safety category is determined
as an entire system. It is recommended to consult a certification body
regarding assessment of conformity to the required safety level.
Precautions for Safe Use
(1)
D40A must be used with 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
Do 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) In direct 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 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 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 vloltage is in the rated range.
(8) Do not use D40A in the water or continuous water exposure
environment, otherwise water may leak into D40A. (An
enclosure of IP67 rating, which D40A is rated, protects against
temporary immersion in water.)
(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 D40A actuator and switch in an appropriate distance so
that it does not create a gap accessible to the hazard.

Total wiring length 100m max.
(5) Disconnect G9SX-NS
from power supply when replacing D40A.
Devices connected to G9SX-NS
may operate unexpectedly.
(6)
Adhesion of solvent 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.

Do not apply a t ensile strengt h of 50N or great er t o the cables.
(17)
In a residential environment, this product may cause radio
interference, in which case the user may be required to
take adequate measures.
(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.
Suggested surge absorber's specification is as follows:
-Peak pulse power: 600W (10/1000μs) o r more
(Per IEC61000-4-5(surge immunity))
-Breakdown voltage: 27-33V
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 following
condition that the switch and actuator target marks are on the same
axis and the sensing surfaces are exactly parallel condition.
