high-speed response been achieved, regardless number beam channels, calculation safety distances each individual sensor longer necessary. This high-speed response simplifies entire process safety distance calculation. Increasing safety distance response speed allows safe distance between danger areas light curtain reduced, thus allowing miniaturization equipment.

safety light curtain that used variety work environments Providing `safety every workplace world
SF4-AH series integrates reliability, economy ease installation, with excellent specifications, fully compliant with Safety category This versatile light curtain well suited wide variety safetyrelated applications, allowing utilized almost workplace.
Convenient tool facilitates easy beam alignment Reduces installation time significantly
beam-axis alignment indicators distributed sensors four sections. indicators sections whose beams aligned light red, allowing user easily verify which beam axes have become aligned. Once beams have become aligned, indicators light green. Upon beginning alignment, soon bottommost topmost beam axis (the standard beam axis) becomes aligned, then corresponding bottommost topmost alignment indicator light will begin blinking red. Therefore, beam axes easily aligned performing initial beam axis alignment either bottommost topmost beam axis, then rotating light curtain around axis this beam. beam-axis alignment indicators provided both emitter receiver, that glance which beams aligned. Beam axes correctly aligned

Upper indicators light Lower indicators light
Even though some beam channels aligned, user cannot determine which beam channels aligned (Cannot determine which beam axes aligned) Only beam axes lower blocks correctly aligned (Beam axes upper blocks correctly aligned)
Even though beam channels only partially aligned, user determine which beam channels aligned (Beam axes upper blocks aligned beam axes lower blocks aligned) beam channels correctly aligned
Only bottommost channnel beam axis correctly aligned
First, ensure that bottommost channel beam axis correctly aligned

Alignment beam axes accurately performed prior power-up
SF-LAT-2N Laster Alignment Tool utilized, then beam axes alignment quickly easily performed, using easy-to-see laster beam spot, even when light curtain units installed long distances apart. addition, SF-LAT-2N Laster Alignment Tool battery-operated; beam axes alignment performed before actual power-up light curtain itself.
Mounting bracket enables easy beam-axis alignment
beam-axis alignment easy since angle adjustment possible with enclosed rear mounting bracket (MS-SF2N-1). Furthermore, optional side mounting bracket (MS-SF2N-3) also used side mounting. Rear mounting bracket

Incorporates advanced ELCA function that prevents mutual interference reduces interference from extraneous light
Recognizes extraneous light prevents malfunctions
This function allows sensor recognize reject interferences instantaneous extraneous light emitted from peripheral equipment, thus preventing malfunctions caused variety sources, including: other sensor beams vicinity operating sensor, beam spatter, rotating light sources. reducing number malfunctions caused extraneous light, detection operations will interrupted less frequently, resulting tremendous improvements work efficiency.
Mutual interference reduced without need interference prevention lines
ELCA (Extraneous Light Check Avoid) function enhances mutual interference prevention function. ELCA decreases interference from extraneous light having similar frequency light used SF4-AH series, thereby also minimizing mutual interference among nearby SF4-AH series sensor units.
SF4-AH series equipped with emitting light amount control function, thus minimizing interference with peripheral sensors
Reducing amount light emitted from emitter facilitates minimization effects such emitted light peripheral equipment. (This function selected using Handycontroller.)
Reducing mutual interference High immunity interference from extraneous light
Reductions total costs possible using series connections
Using optional serial connection cable, maximum sets sensors connected series. Previously, separate wiring required sets sensors. now, wiring equivalent that only required, thus saving troublesome wiring costs. well, fewer power connections required, thus reducing number safety relay units needed single unit, resulting tremendous cost reductions.
