•Use this device as per its specifications. Do not modify this device since its
functions and capabilities may not be maintained and it may malfunction.
•This device has been developed/produced for industrial use only.
•Do not use this device under conditions or in environments not described in
this manual. Please consult us if there is no other choice but to use this
device in such an environment.
•Do not use this device in fields such as nuclear power control, railroad,
aircraft, automobiles, combustion facilities, medical systems, aerospace
development, etc.
•When this device is to be used for enforcing protection of a person from any
danger occurring around an operating machine, the user must satisfy the
regulations established by national or regional security committees.
•In case of applying this device to particular equipment, follow the safety
regulations in regard to appropriate usage, mounting (installation), operation
and maintenance.
•Use this device by installing suitable protection equipment as a
countermeasure for failure, damage, or malfunction of this device.
•Before using this device, check whether the device performs properly and
has the functions and capabilities as stated in the design specifications.
•Dispose of this device as industrial waste.
Environment
•Do not use a mobile phone or a radio phone near this device.
•If the device is installed in a place where there are reflective surfaces, make
sure to install this device so that reflected light from the reflective surfaces
does not affect the receiver. Alternatively, take countermeasures such as
painting, masking, roughening, or changing the material of the reflective
surfaces, etc. Failure to do so may cause the sensor not to detect properly,
which may result in death or serious injury.
•Do not install this device in the following environments.
- Areas exposed to intense interference light such as direct sunlight
- Areas with high humidity where condensation is likely to occur
- Areas exposed to corrosive or explosive gases
- Areas exposed to vibration or shock at levels higher than those specified
- Areas exposed to contact with water
- Areas exposed to too much steam or dust
- Areas where the beam-receiving part of this device is directly exposed to
light from a high-frequency fluorescent lamp (inverter type) or
rapid-starter fluorescent lamp.

Installation
•Always keep the correctly calculated safety distance between this device
and the dangerous parts of the machine.
•Install an extra protection structure around the machine so that the operator
must pass through the sensing area of this device to reach the dangerous
parts of the machine.
•Install this device in a manner that some part of the operator's body always
remains in the sensing area until the operator has finished working with the
dangerous parts of the machine.
•Do not install this device at a location where it can be affected by wall
reflection.
•When installing multiple sets of this device, connect the sets and, if
necessary, install some barriers so that mutual interference does not occur.
•Do not use this device in an environment with reflective light.
•The corresponding emitter and receiver must have the same serial number
and be correctly oriented.
Equipment in which this device is installed
•When this device is used in the PSDI (see page 160) mode, an appropriate
control circuit must be configured between this device and the machinery.
For details, be sure to refer to the standards or regulations applicable in each
region or country.
•In Japan, do not use this device as safety equipment for a press machine or a
shearing machine.
•Do not install this device with a machine whose operation cannot be stopped
immediately in the middle of an operation cycle by an emergency stop.
•This device provides safety 2 seconds after the power has been switched
ON. Make sure that the control system takes the time delay into
consideration.
Wiring
•Switch off the power before wiring the device.
•All electrical wiring should conform to the regional electrical regulations and
laws. The wiring should be done by engineer(s) having the required electrical
knowledge.
•Do not run the sensor cable together with high-voltage lines or power lines
or put them together in the same raceway.
•In case you need to extend the cable of the emitter or the receiver, you can
use the dedicated extension cable. The cable can be extended up to 50m.
However, if the cable is extended in an installation with multiple sensors
connected in series or with the muting lamp (see page 91), the total
extendable length of the cable depends on the number of the sensors
connected in series (see page 52).

Part Description
Emitter Emits light to the receiver facing it. Furthermore, the status of the emitter is indicated on
its display section.
Receiver Receives light from the emitter facing it. Simultaneously the control output (OSSD 1,
OSSD 2) turns ON when the all beam channels receive light from the emitter, and the
control output (OSSD 1, OSSD 2) turns OFF when one or more beam channels are
blocked. The receiver displays its status on the display section.
Beam channel The light-emitting elements of the emitter and the light-receiving elements of the
receiver are placed at the following intervals: 10mm (SF4B-F), 20mm (SF4B-H), and
40mm (SF4B-A).
Standard mounting
bracket (optional) Use this bracket to mount the emitter/receiver. The standard mounting bracket allows
you to adjust the horizontal mounting angle.
M8 mounting bracket
(optional) This allows the light curtain to be mounted at the rear with one M8 hexagon-socket-head
bolt. The horizontal angle can be adjusted.
Pitch adapter bracket
(optional) This bracket is used when you change from a previous light curtain with a sensing
height of 200 to 750mm to this device. The bracket is installed using two M5
hexagon-socket-head bolts. The horizontal angle can be adjusted.
M8 pitch adapter
bracket (optional) This bracket is used when you change from a previous light curtain with a sensing
height of 200 to 750mm to this device. The bracket is installed using two M8
hexagon-socket-head bolts. The horizontal angle can be adjusted.
