Long sensing range of up to 15 m 49.213 ft [Sensor head]

Secures safety of large facilities where installation of guardian fence is difficult.

Series connection of sensors and interference prevention [Sensor head]

The numbers of sensor heads and controllers can be freely adjusted to meet the heights and the required numbers of the protection area.

Beam axis alignment and operation confirmation [Sensor head]

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.

Supports beam axis alignment at startup and quick restoration in case of trouble [High-functional type ST4-C12EX]

Light received condition of the sensor heads in series connection can be confirmed by the high-functional controller ST4-C12EX.
In addition, any abnormal sensors during lockout can be identified.

Compact sensor head saves space

The Type 4 long sensing range type has a compact size that is equivalent to those of general-purpose photoelectric sensors.

Industry standard mounting pitch [Sensor head]

Having the same mounting pitch as those of general-purpose photoelectric sensors makes model switchovers easy.

Protection structure IP67 [Sensor head]

Conforming to protection structure IP67, the sensor heads can be used safely even at lines where water splashes.

Control of interferences to surrounding sensors [Sensor head]

The emission amount adjuster can be used to reduce the emission to control any interference to the surrounding sensors.

Supports both PNP and NPN polarities [Controller]

A single unit can be used for PNP / NPN output switching, reducing the number of parts that need to be registered.

Easy connector connection [Controller]

Connecting to the sensor head is done using connector connections, which shortens setup and replacement time.

Semiconductor output reduces running costs! [Controller]

Semiconductor output is used for control output. This means there is no need to periodically replace safety relays.

Error details can be understood at a glance! [High-functional type ST4-C12EX]

If a problem should occur, the control output is switched OFF, and the details of the error appear on the digital display.

Three patterns of muting control function for greater safety with no loss in productivity [High-functional type ST4-C12EX]

Sensor heads, muting sensors, and muting lamps connect directly to the controller, so that muting control circuits can be built easily.

Muting pattern No.1

Compliant to international safety standard ISO 12643 for printing industry

Muting area can be changed to suit the printing process. This is the optimal muting control for printing machines.

Muting pattern No.2

Set apart only the top-most sensor heads and perform muting control.

Muting pattern No.3

Divide the muting area into two.

Line restarts smoothly after being stopped while muting control was active <Override function> [High-functional type ST4-C12EX]

In case the sensor head has been interrupted by an object or in case there is an emergency stop before the muting conditions have been established, all the sensor heads will be temporarily deactivated following by a smooth restart.
