Safety Categories
Different types of machines will have different levels of associated risk. As an index
for determining the function to secure safety (safety function) based on the risk
evaluation, the ISO 13849-1 which stipulates safety-related parts of control
systems, categorizes the capability to maintain safety functions in the event of
control system failures as category B to 4.
Performance Level (PL)
An index of the safety control system performance level shared by a person who
implements risk assessment and a person who designs a machine is called
Performance Level (hereinafter abbreviated as "PL") and has 5 levels of evaluation
from "a" to "e".
For details on safety category and PL, refer to page 5.

D40Z Features
High level of safety for a wide range of applications
ISO 13849-1 (PLe/Safety Category 4) achieved with Non-contact Door Switches
• Self-diagnostic Function
OMRON’s unique electromagnetic induction system for safety was achieved by implementing a detection function for external wiring
errors in the Switch.
• Redundant internal circuits
The thorough pursuit of safety is evident in mutual checking by double CPUs.
Series connections
• Up 30 Switches can be connected to one Controller while maintaining PLe/safety category 4.
The D40Z can be connected to G9SP or G9SX-NS
Safety Controllers. Select the best model for your application.

short-circuits in D40Z I/O wiring.
Faults may not be detected,
e.g., for short-circuits in
switch I/O wiring.
Electromagnetic induction method
• Enables stable detection
• No adhesion of iron particles
With these electronic switches, stable detection is possible
even when the door closes slowly.
Permanent magnets are not used, so iron is not attracted,
making maintenance easier.
Visible safety
Checking at the production site
Centralized monitoring
The switch's LED indication
patterns make identification of
abnormal condition possible at
the production sites.
Note: For more information,
refer to page 10.
Bipolar NPN/PNP allows for easy connection with any PLC.
The error location can be easily identified. Using a branch
relay for a different pole is not required.

For an easier and safer work
environment in all industries.
The application of the D40Z will
continue to increase in all environments.
Automotive manufacturing
(multi-axis robot)
Problem
Detecting the position of a multi-axis
robot is difficult using a limit switch.
Additionally, it is easy to disable the
function.
Solution
The non-contact door switch enables
ease in detecting the robot position
which prevents the operator from easily
disabling the function.
The maintenance work is safer than
ever as the switch conforms to ISO
13849-1 (PLe/safety category 4).

narrow space (Switch: 48x48x25 mm,
Actuator: 48x48x17 mm). The D40Z can
be used at an ambient operating
temperature of up to 65°C.
Key
factor

Problem
Although safety is ensured with a
contact door switch, particles are
generated which affect product quality.
Solution
With the non-contact door switch D40Z,
no particles will be generated through
friction.

to loss of safety functions.
9. Do not apply DC voltages exceeding the rated voltages, nor any
AC voltages to D40Z.
10.Use a DC supply satisfying the requirements given below to
prevent electric shock.
- A DC power supply with double or reinforced insulation, for
example, according to IEC/EN 60950 or EN 50178, or a
transformer according to IEC/EN 61558.
- A DC supply satisfying the requirements for class 2 circuits or
limited voltage/current circuits stated in UL 508.
11.Connect the D40Z to 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 must be determined for the entire system. It is
recommended to consult an authorized certification body
regarding assessment of conformity to the required safety level.

4. Do not use D40Z at altitudes over 1,000 meters.
5. Do not use to connect other switches or sensors to the wire
conductors of D40Z.
6. Disconnect D40Z and the controller connected to D40Z from
power supply when replacing D40Z. Failure to do so may cause
unexpected operation of devices connected to D40Z.
7. Keep D40Z from solvent such as alcohol, thinner, trichloroethane
or gasoline. Such solvents make the marking on D40Z illegible and
cause deterioration of parts.
8. Do not use D40Z in the magnetic field of 1.5 mT or more, otherwise
D40Z may not function properly.
9. Do not use D40Z in the water or continuous water exposure
environment, otherwise water may leak into D40Z. (An enclosure
of IP67 rating, which D40Z is rated, protects against temporary
immersion in water.)
10.Do not use D40Z switch or actuator as a stopper. Use a stopper to
protect the switch and the actuator. Keep a distance of at least 1
mm between the switch and the actuator.
11.Be sure to install D40Z switch and actuator in such as appropriate
distance that does not create a gap accessible to the hazard.
15
D40Z
12.When installing two or more adjacent switches, keep a distance of
at least 50 mm from one another.
50 mm min.
17.Use cables of a total length of 100 m max. to connect multiple
D40Z switches. However, the total length of 200 m max. is
possible depending on the number of D40Z switches connected.
The supply voltage to D40Z may decrease by the voltage drop
depending on the cable or the wiring configuration. Check the
power-supply voltage is in the rated range.
30 or less D40Z connected
15 or less D40Z connected
13.Be sure that the machine is stopped whenever the guard door is
open.
(Note 1)
Total wiring length 200 m max.
Total wiring length 100 m max.
14.Mounting the switch and actuator on metal may affect the
operating distance. If there nearby devices that generate strong
radio waves or magnetic fields, they may also affect the operating
distance through the metal. Do not mount the switch and actuator
directly on metal.
When installing them on a metallic material, be sure to verify such
an effect before using. Refer to the following table for the
estimated effects of mounting on metal on the operating distance.
Type of metal
Operating distance
Iron
Approx. 75% of normal distance
Aluminum
Approx. 85% of normal distance
Stainless steel
Approx. 85% of normal distance
We recommend that you separate the switch and actuator at least
10 mm from all nearby metal.
15.Use M4 screws with a maximum diameter of 7mm and washers to
install the switch and actuator. Tighten the screws with a specified
torque. After installing and commissioning, coat the switchactuator fixing screws with tamper-proof varnish or similar
compound for locking. Using anaerobic locking compounds can
have a detrimental effect on the plastic switch case if the
compounds contact with the switch case.

you use D40Z near such equipment, be sure to verify effects of
such equipment on D40Z before using.
20.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.
21.To determine safety distance to hazards, take into account the
delay of non-contact door switch output caused the response time.
22.If there is any machine that has a large surge current (e.g., a
motor) near D40Z, connected a surge absorber to D40Z between
the blue and the other cables (white, black and brown)
respectively, or between the yellow cable and gray cable.
Suggested surge absorber's specification is as follows:
- Peak pulse power: 600 W (10/1000 μs) or more
(Per IEC 61000-4-5 (surge immunity))
- Breakdown voltage: 27-33 V
