Delivering global standard safety
Safety level required global standards
`Safety' joined `Environment' keywords century. Machinery principal area where importance given safety issues been increasing throughout world, this been leading global standardization safety levels. 2001 later 12100 international safety standard will established line with this trend toward safety standardization. This standard based standards which operation Europe, area which been very progressive promoting safety. same time, other countries around world have been reviewing their safety standards.

High Level Safety Achieved
sensor carries self-diagnosis when turned monitoring section (CPU) which inside emitter constantly checks emitting circuit control circuit. Furthermore, receiver also monitoring section (CPU) which constantly checks receiving circuit, control circuit output circuit, that high level safety maintained times.
Safety design SF2-N series
sensor switches lockout mode when error occurs, that OSSD (control output) alarm output turn OFF. output transistors connected series provide duality, that sensor also locks transistors short-circuited. Self-diagnosis using test input allows detailed checking such overlapping emission (overcurrent error), light emission strength, etc.

High-performance sensors meeting needs workplaces around world
SF2-N series sensors utilize latest advances SUNX sensor technology provide variety useful functions while meeting international standards. They combine level safety required such standards with truly remarkable ease use. newly-developed light curtain, with radically features, contributes greatly improved safety workplace.
World's Smallest Design, with Exclusive Controller Required
Compact Design, 28mm Wide 19mm Thick
design compact, with width only 28mm thickness 19mm, exclusive controller required, that minimum space required installation. small amount space needed allows sensors incorporated into machinery.
Small installation space Streamlined layout
Machiner safety circuit
Incorporates Extraneous Light Checking Function
Distinguishes Extraneous Light Prevent Malfunction
(Extraneous Light Check) function prevents malfunction extraneous light, such from other nearby passing sensors, AGVs, patrol lights spatter light.
What Extraneous Light Check (ELC) function? This function distinguishes between light from sensor itself light from extraneous sources, reduces effect extraneous light received sensor.
Variety Features Provide Greater Ease Workplace
Convenient Indicators Allow Easy Beam Alignment
beam-axis alignment indicators distributed sensors four sections. indicators sections whose beams aligned light red, when beams aligned, indicators light green. beam-axis alignment indicators provided both emitter receiver, that glance which beams aligned.
Width
28mm
Slit Masks Boost Functionality
using optional slit mask (OS-SF2N-A amount beam emitted received restrained reduce effect extraneous light from other sensors, etc.

Front Protection Cover Protects Mounting Bracket Enables Sensing Surface Easy Beam-axis Alignment
optional front protection cover (FC-SF2N-A fitted sensor protect sensing surface even when using sensor poor environmental conditions.
Front protection cover
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
Thickness Operating range
19mm
Wire-saving Series Connection
Covers Even L-shaped U-shaped Areas
Using optional serial connection cable, maximum sets sensors with total beam channels (for 20mm beam pitch type) beam channels (for 40mm beam pitch type) connected series. Hence, even Lshaped U-shaped areas easily covered. Previously, separate wiring required sets sensors. now, wiring equivalent that only required, thus saving troublesome wiring costs.

Wide Variety
Different Types Different Needs
There types sensors having beam pitch 20mm (detection capability "30mm) protective height ranging from 140mm beam channels) 1,260mm beam channels). Plus, there types sensors having beam pitch 40mm (detection capability "50mm) protective height ranging from 120mm beam channels) 1,560mm beam channels). sensors selected from this wide variety suit your requirement. output types also available models.
