The numbers of sensor heads and controllers can be
freely adjusted to meet the heights and the required
numbers of the protection area.
The beam interruption indicator is incorporated in both
the emitter and receiver. This indicator can be used not
only for operation confirmation but also for beam axis
alignment. Moreover, the stability indicator indicates
if the incident light intensity exceeds 150 % in stable
operation.

PRECAUTION FOR PROPER USE
If there exists a reflective surface in the place
where this device is to be installed, make sure
to install this device so that reflected light from
the reflective surface does not enter into the
receiver, or take countermeasures such as
painting, masking, roughening, or changing the
material of the reflective surface, etc. Failure
to do so may cause the device not to detect,
resulting in death or serious injury.
• Install this device at a distance of at least A (m) (given
below) away from reflective surfaces such as metal walls,
floors, ceilings, objects, covers, panels or glass surfaces.

L / 2 × tan 2θ = L × 0.053 (m) 0.174 (ft) (θ = 3°)
Note: The effective aperture angle for this device is ±2.5° (when L > 3 m
9.843 ft) as required by IEC 61496-2 / UL 61496-2. However, install
this device away from reflective surfaces considering an effective
aperture angle of ±3° to take care of beam misalignment, etc. during
installation.

Refer to the applicable regulations for the region
where this device is to be used when setting up the
device. In addition, make sure that all necessary
measures are taken to prevent possible dangerous
operating errors resulting from earth faults.

Influence of reflective surfaces
ST4 SERIES
• Make sure to carry out the wiring in the power supply off condition.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching
regulator, ensure that the frame ground (F.G.) terminal of
the power supply is connected to an actual ground.
• In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this sensor and controller, connect
the frame ground (F.G.) terminal of the equipment to an actual ground.
• Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
• It is recommended that the following single wires or twisted wires
(lead wires) be used to connect to the terminal block of the controller.
• Terminal block connector: 0.2 to 1.5 mm2 (AWG24 to AWG16)
• Power supply connector (A1, A2) (ST4-C12EX only):
0.2 to 2.5 mm2 (AWG24 to AWG12)
Others
• This device has been developed / produced for industrial
use only.
• Do not use during the initial transient time (2 sec.) after
the power supply is switched on.
• Avoid dust, dirt and steam.
• Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
• Take care that the sensor is not directly exposed to
fluorescent lamp from a rapid-starter lamp or a high frequency
lighting device, as it may affect the sensing performance.
• The DC power supply unit must satisfy the conditions given below.
1) Power supply unit authorized in the region where this
devices is to be used.
2) Power supply unit conforming to EMC Directive and Lowvoltage Directive (In case CE conformity is required).
3) Power supply unit conforming to the Low-voltage
Directive and with an output of 100 VA or less.
4) The frame ground (F.G.) terminal must be connected to ground
when using a commercially available switching regulator.
5) Power supply unit with an output holding time of 20 ms or more.
6) If surges are likely to occur, take countermeasures such
as connecting a surge absorber to the origin of the surge.
7) Power supply unit corresponding to Class 2 (In case UL /
cUL conformity is required).
