Resistant to impact, less damage to workpiece　Robust type SF4B-□G□<V2>

Thick and robust housing resistant to impact

The SF4B-G series safety light curtain is enclosed in a 5 mm 0.197 in thick robust metal case, protecting the workpiece from various types of impact, such as collision or being stepped on.

Fully protected sensing surface

The sensing surface is fully protected by narrowing and deepening the exposed area of the sensing surface.

Round design minimizes damage to the workpiece

The case is designed so that shock upon impact is dissipated alleviating potential damage to the workpiece in the event of a collision.

Workpiece not contaminated with paint

The body has an alumite-treated case so that paint does not stick to the workpiece in the event of a collision.

Enables series connection with standard type possible

The mating cable is standard, allowing the robust and standard types to be connected in series.

No guard needed

The robust type can be used without an L-shape or U-shape guard, reducing installation and maintenance.

Front protection cover

The front protection cover protects the sensing surface from welding spatter and reduces damage due to collisions.
The beam axis adjuster can be attached without removing the front protection cover.

Protection structure IP67

The seamless structure protects the sensor from being exposed to water.

Mounting bracket for simple & secure installation

The safety light curtain and the mounting bracket are firmly secured with just two bolts.
The safety light curtain is situated in the center of the mounting bracket, preventing beam axis deviation.
The dimple structure makes alignment easy to adjust.

Black and yellow caution tape

Black and yellow striped attention tape is attached to the side of the safety light curtain, alerting workers to use caution. Hazardous openings are very obvious.

A large reduction in cost by using corner mirror (optional)

A single corner mirror makes it possible to eliminate one safety light curtain set and its associated peripheral safety circuits.
This enables costs to be greatly reduced, and also eliminates wiring needs.
The control category is unchanged.

Normally for L-shaped or U-shaped installation, 2 or 3 sets of safety light curtains are needed. With the use of a corner mirror reflecting the light, one set of safety light curtain is possible for L-shaped or U-shaped installation.
