Robust Light Curtain [Category4 PLe SIL3] SF4B-□G Ver.2

■Thick and robust housing resistant to impact
The SF4B-G series 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.

■No guard needed
The robust light curtain can be used without an L-shape or U-shape guard, reducing installation and maintenance.

■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 a alumite-treated case whereby paint does not stick to the workpiece in the event of a collision.

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

■Enables series connection with standard type possible
The mating cable is standard, allowing the robust and standard types to be connected in series. The mating cable can be removed or attached while the mounting bracket is fixed, allowing easy maintenance.

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