The internal unit was redesigned and downsized extensively.
The internal unit was downsized to less than 40% (volume ratio) as compared to the conventional model while achieving higher performance.
The case structure was also optimized and offers high rigidity without any change in external dimensions.
The SF4D series provides high performance and high reliability while maintaining the installation and wiring compatibility with the previous models.
Completely new mounting brackets and structure. In addition to strengthening the rigidity of the mounting brackets, we have also improved the method of attachment to the safety light curtain unit
to significantly increase the mount strength. The dead zoneless mounting bracket and the optional mounting bracket* that does not extend from aluminum frame are also available for easier use.

The power of the emitter has been increased significantly. The high resistance to dust and dirt contributes to the reduction of maintenance frequency.
Minimization of deviations among elementsWe incorporated the element alignment technology that we cultivated for fiber sensors in the safety light curtain. This minimizes curves due to emitter and receiver mounting deviations and quality deviations due to differences in individual elements. Redesigned emitter element layout and structureThe scattering light energy from each emitter element is guided efficiently through the lens. The light energy of the emitter element is utilized fully, and the light distribution characteristics were optimized for the specific aperture angle.*
|
* The aperture angle of a Type 4 safety light curtain is specified as a maximum of 2.5° each on the right and left at a detection distance of 3 m 9.843 ft or more. |
The SF4D series complies with IP67 and IP65 (IEC) as well as NEMA Type 13 (NEMA 250)*1.
The unit structure prevents the entry of not only water but also coolant and other liquids*2 to protect the internal unit.

The light incidence margin is indicated by the “stable light incidence indicator” and “digital indicator”. This function enables appropriate beam adjustment and work quality control during installation of the device. The indicators also show whether there is dirt on the detection surface or beam misalignment due to play.
This enables the numeric display to be used for startup inspection and preventative maintenance.
* When optical synchronization is set, only the indicator on the receiver lights up.
|
Light incidence intensity indicationThe indicator shows the light incidence margin with a numeric display (1 to 3).
|
Polarity indicationThe indicator shows the set polarity when power is turned on. This makes it easy to confirm proper operation after wiring.
|
Error indicationThe new series is also equipped with the error indication function, a well-received feature of our previous models. In an environment where a PC cannot be brought in or when a problem occurs at a remote location, the displayed error number lets you identify the cause of problem. This facilitates restoration work.
|
The application indicator improves work efficiency in a variety of ways by providing support to work activities ranging from daily equipment operation to installation and maintenance. The indicator function can be switched between two options.
|
Can light and blink in three colors (green, red, and orange) according to an external input. The indicator can be used to indicate work instructions or equipment status.

【COLUMN】
The stable light incidence indicator is commonly used when installing a new safety light curtain to equipment or when checking if the existing safety light curtain is operating properly. Previously, however, even if the stable light incidence indicator was ON, there was no way of knowing whether there was an ample margin or the condition is close to unstable light incidence.
The SF4D series not only shows whether the light incidence is stable or unstable but also the amount of margin with a numeric display. Therefore, it is possible to numerically manage the stability margin of the safety light curtain. When the amount of received beam intensity decreases during equipment operation due to oil mist or other reasons, the digital display shows the stability margin of the safety light curtain. Thus, cleaning can be scheduled and conducted at the most suitable timing.
The OFF response time of the control outputs (OSSD 1, OSSD 2) of the SF4D series is 10 ms or less, the fastest class* in the industry (when not connected in series or in parallel). [18 ms or less when connected in series or in parallel] The SF4D series contributes to the reduction of equipment size.

Uses the well-received front access cable of previous models. The cable can be attached and detached after the safety light curtain is installed on the equipment. This allows easy replacement in the event that the cable is damaged.
Up to five units (1 main sensor and 4 sub-sensors) can be connected in series, and the maximum number of beams has been increased to 256. This provides extra convenience when installing additional equipment, when increasing the detection width (protection height), and when using one system for protection of multiple locations.
When choosing and installing a safety light curtain, the synchronization method and cable can be selected flexibly according to the customer's specific application and needs, such as the basic configuration or safety-enhanced configuration with improved operability.
