(3) Keep the product away from oil or solvent. Oil or solvent make
the marking on the product illegible and cause deterioration of
some parts.
(4) Do not use in an environment with corrosive gas.
(5) The product may not operate normally in the vicinity of devices
that generate strong radio waves or magnetic fields, such as
RFID systems, proximity sensors, motors, inverters, and
switch-mode power supplies. If the device is used in the
vicinity of such devices, check the effect before use.
(6) Installing the switch and the actuator on a metallic material
may affect the operating distance. If installation on a metallic
material is necessary, be sure to check the effect on the
operating distance before use.
(7) Tighten the screws with a specified torque.
(8) Use the wires specified by OMRON to wire the product.
(Refer to Connection.)
(9) Do not extend the cables in excess of the specification of this
product. Carry out electrical connection according to the wiring
examples shown in this document and verify the correct
operation of the product.
(10) During installation, make sure that the safety door switch does
not come in contact with the actuator due to rattling of the
guard door. (The performance of the product may be degraded
by a collision caused by opening or closing the guard door.)
(11) Do not pull or bend the cable excessively. A disconnection
may cause a malfunction.
(12) Risk time remains unchanged by series connection. However,
carry out electrical connection according to the wiring
examples shown in this document.
(13) Be sure to inspect the product daily and every 6 months.
Failure to do so may cause a system failure and serious injury.
(14) When determining the safety distance, take into account the
delay of the output of the product caused by the response time.
Failure to do so may cause the operator to reach the hazardous
source before the machine is stopped, resulting in serious injury.
(15) Install the product so that the LED indicators of the safety
door switch are as visible as possible. Misinterpreting the
status of the safety door switch may result in danger.
(16) Do not use the product at an altitude of 2,000 m or higher.
(17) Do not connect a product different from this product in series
with this product. Doing so may disturb waveforms of the
input and output signals, leading to loss of the safety function.
(18) Do not use the product in the water or continuous water
exposure environment. Doing so may cause water to leak into
the product. (The degree of protection does not guarantee the
protection under continuous water exposure environment.)
(19) Do not tamper the product with a replacement actuator. Store
replacement actuators in a safe place where they cannot be
easily reached.
(20) Build a safety system using the outputs of both Safety
Outputs 1 and 2. Wiring with only one safety output may lead
to loss of the safety function due to a single failure.
(21) Wiring should meet the requirements specified in Section
9.4.3 of IEC 60204-1 to prevent malfunction due to ground
faults in the safety output lines.
(22) Do not wire the product to an input of a safety controller in parallel.
(23) Do not try to disassemble, repair, or modify the product.
Doing so may cause loss of the safety function.
(24) Do not operate the product in an environment with flammable
or explosive gas.
(25) After installation of the product, qualified personnel should verify
to see that the installation, inspection, and maintenance are
properly performed. The qualified personnel should be qualified
and authorized to secure the safety on each phase of design,
installation, running, maintenance and disposal of system.
(26) 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.
(27) Disconnect the product and the controller connected to the
product from power supply when replacing the product.
Failure to do so may cause unexpected operation of devices
connected to the product.
(28) The safety function may not operate normally due to a
malfunction of the wiring, setting, or switch, and the machine may
continue to operate, which may result in personal injury. Make
sure that the safety function works before starting operation.
(29) Do not use the product as a door stopper. (The performance
of the product may be degraded due to a collision caused by
opening and closing the guard door.)
(1) Do not drop the product to the ground or expose to excessive
vibration or mechanical shocks. Doing so may damage the
product and cause failure.
(2) Do not store or use the product under the following conditions.
Doing so may damage the product and cause failure.
1) At ambient operating temperatures out of the range of -25 to 65°C
2) At ambient storage temperatures out of the range of -25 to 85°C
3) At relative humidity of 93% or more
4) In direct sunlight
5) Under drastic temperature changes
6) In high humidity that causes condensation
Operating distance
The side allows for a maximum height misalignment (X) of safety
door switch and actuator of ±8 mm (e.g. mounting tolerance or due
to guard door sagging). The axial misalignment (Y) is max. ±18 mm.
Actuating curves
The actuating curves represent the typical operating distance of
the safety door switch during the approach of the actuator subject
to the actuating direction.
The continuous signal of the yellow LED signals the actuator
detection; the flashing of the yellow LED signals that the safety door
switch is actuated in the different travel area.
Preferred actuation directions: from front or from side
In case of a lateral actuation, the operating distances are reduced
by approx. 3 mm.
Recommended Adjustment
Align the safety door switch and actuator at a distance of 0.5 x
assured operating distance (Sao).
The correct functionality of both safety channels must be checked
by means of the connected safety controller.
The mounting holes provide for a mounting by means of M4 screws
(max. tightening torque 0.8 N•m). The product can be mounted in any
position. The minimum bend radius of the -025-type cable is 25 mm.
The active areas of the safety door switch and the actuator have to
face each other. The safety door switch must only be used within the
assured operating distances ≤ Sao and ≥ Sar.
To avoid any interference inherent to this kind of system and any
reduction of the operating distances, please observe the following
guidelines:
• See the figures below for the minimum distances between two safety
door switches and other systems of the same frequency (125 kHz).
Sealing Kit (D41D-SK)
Contents: 4 flat plugs and 4 plugs with rim for high screw head
Purpose: Used to seal the mounting holes
Mounting Kit (D41D-MS)
Contents: 2 mounting plates and 4 ferrule plugs
Purpose (Mounting plate): Used to fix to a non-flat surface such as a
profile.
Purpose (Ferrule plug): Used for applications with considerable
changes in ambient temperature.
Note: 1. Lateral actuation only from the shown side of the safety door switch.
Note:1. If multiple safety door switches are involved in the same
safety function, the PFH values of the individual
components must be added.
For use in NFPA 79 Applications.
Adapters providing field wiring means are available from the
manufacturer. Refer to manufacturer's information.
For use in Pollution Degree 2 Environment.
