1 SF-N SERIES Small Diagnosis Self-diagnosis Test input PNP output type available Type We changed unstable incident beam indicator orange LED) to stable incident beam indicator orange / green LED) from the production in June, 03. By this change, you can see more stable state of incident beam at a glance, and you can align beam axis accurately. [Operation of stable incident beam indicator EX-unstable incident beam indicator)] When light received is stable Amount of light received more than 1 % approx.) When light received is stable Amount of light received 115 to 1 % approx.) When light received is unstable Amount of light received 0 to 115 % approx.) When light is interrupted when OSSD is off) Stable incident beam indicator After modifications Previous products Lights up in green Bringing world-class safety standards even closer to you Type Standard type Off Lights up in orange Off Off Off Lights up in orange Off Conforming to Machine Directive & EMC Directive Approved Listing Application of IEC Type ) international standard The series conforms to European and North American safety standards. So, they can be used in workplaces throughout the world. High level of safety achieved The sensor carries out self-diagnosis when it is turned ON. The monitoring section CPU) which is inside the emitter constantly checks the emitting circuit and the control circuit. Furthermore, the receiver also has a monitoring section CPU) which constantly checks the receiving circuit, control circuit and output circuit, so that a high level of safety is maintained at all times. Conforming to Machine Directive & EMC Directive Europe Approved Listing CE marking based on Machine Directive and EMC Directive has been obtained, so that the sensors can be used in Control Category equipment. Type based on IEC /, EN and Control Category based on EN North America C-UL US listings UL /) which are required for use in the United States and Canada have been obtained. Safety design of the series The sensor switches to the lockout mode when an error occurs, so that the OSSD control output) and alarm output turn OFF. The output circuit is constantly monitored, so that the sensor also locks out if one of the transistors is short-circuited. Self-diagnosis using test input allows detailed checking such as overlapping emission overcurrent error), light emission strength, etc. Alarm output Alarm output Control circuit Check Monitoring section CPU) Emitting element failure Emitting circuit failure Emitting circuit Receiving circuit Synchronization line Control circuit Check Receiving element failure Receiving circuit failure Check Monitoring section CPU) Output circuit Check Output transistor failure CPU malfunction OSSD control output) Test input Cable breakage / short-circuit Extraneous light Cable breakage / short-circuit 446

2 Space-saving design only mm 1. in width and 19 mm in thickness With its mm 1. in width and 19 mm in thickness, it is the smallest in the world* requiring the least installation space in the industry. It can be installed in small spaces incorporated within equipment. * Data valid as of June 0 and based on research conducted by SUNX. Operating range 0.3 to 7m to.966 ft Different types for different needs Sensors are available with beam pitches of mm in and mm in. The protective height for sensors ranges from 190 mm in to 1,950 mm in, for both mm in and mm in beam pitch sensors. NPNPNP output types are also available for all models. The sensors can be selected from this wide variety to suit your requirement. LIGHT CURTAINS mm in beam pitch 8 to 96 beam channels mm in beam pitch 4 to 48 beam channels 1,950 mm in SF-N Thickness 19 mm in Width mm 1. in Unaligned beam axes can be seen at a glance 190 mm in The beam-axis alignment indicators are distributed on the sensors in four sections. As the indicators of the sections whose beams are aligned light up in red, the user can easily verify which beam axes have become aligned. Once all beams have become aligned, the indicators light up in green. Upon beginning alignment, as soon as the bottommost or the topmost beam axis the standard beam axis) becomes aligned, the corresponding bottommost or topmost alignment indicator light begins blinking red. Therefore, beam axes can be easily aligned by performing the initial beam axis alignment on either the bottommost or the topmost beam axis, then rotating the light curtain around the axis of this beam. The beam-axis alignment indicators are provided on both the emitter and the receiver, so that you can see at a glance which beams are not aligned. Beam axes are not correctly aligned Only the bottommost beam axis is correctly aligned When the upper half of all beam axes are aligned Conventional unit After all beam channels received light, the number of indicators that light up will increase in accordance with the incident light level Even though some beam channels are aligned, the user cannot determine which beam channels are aligned Cannot determine which beam axes are not aligned Only the beam axes of the two lower blocks are correctly aligned Beam axes of the two upper blocks are not correctly aligned) Upper two indicators: ON Lower two indicators: OFF Even though beam channels are only partially aligned, the user can determine which beam channels are aligned Beam axes of two upper blocks are aligned / beam axes of two lower blocks are not aligned) All beam channels are correctly aligned First, ensure that the bottommost beam axis is correctly aligned Rotate the receiver around the bottommost beam axis Blinking All indicators light off The bottommost indicator blinks red The bottom two indicators light up in red All indicators light up in green 447

3 Recognizes extraneous light and prevents malfunctions This function allows the sensor to recognize and reject interference from instantaneous extraneous light emitted from peripheral equipment, thus preventing malfunctions caused by a variety of sources, including: other sensor beams in the vicinity of the operating sensor, beam spatter, AGV and rotating light sources. By reducing the number of malfunctions caused by extraneous light, detection operations will be interrupted less frequently, resulting in substantial improvements in work efficiency. Mutual interference is reduced without the need for interference prevention lines The ELCA Extraneous Light Check & Avoid) function enhances the mutual interference prevention function. ELCA decreases interference from extraneous light having a similar frequency as the light used by the series, thereby also minimizing mutual interference among nearby series sensor units. SF-N Reducing mutual interference High immunity to interference from extraneous light Spatter protection for the sensing surface The spatter protection hood type, now available, protects the sensing surface from welding machine spatter. Moreover, a front protection cover that can be installed within the sensor casing is also available, completely preventing spatter from adhering to the sensing surface. In addition, even though sensed objects may contact the sensor, the sensing surface will be protected. The ELCA function implements all possible measures to prevent malfunctions caused by spatter. Front protection cover protects the sensing surface In the event that the series is installed in a harsh environment, the use of the front protection cover FC-SF4A-H, optional) will protect the sensing surface from damage. Front protection cover Front protection cover Mounting bracket enables easy beam-axis alignment The beam-axis alignment is easy since angle adjustment is possible with the enclosed rear mounting bracket MS-SFN-1). Alternatively, the side mounting bracket MS-SFN-3) is also available as an option. Rear mounting bracket Alignment of beam axes can be accurately performed prior to power-up By using the SF-LAT-N laser alignment tool, you can quickly and easily align beam axes. The laser beam spot is easy to see, even when light curtain units are installed far apart. In addition, as the SF-LAT-N laser alignment tool is batteryoperated, beam axes can be aligned before powering up the light curtain itself. 1Align the topmost beam axis Track level Align the bottommost beam axis 448

Test input self-diagnosis function) / Emission halt function In order to maintain safety, carry out the self-diagnosis at least once a day. If the test input wire is made open for 45 ms or more, or connected to Vs1.5 V to Vs PNP output type: 0 to1.5 V) detailed diagnosis, in addition to the internal self-diagnosis being done during normal operation, is carried out. In case no abnormality is discovered during self-diagnosis, and if the test input is continued to be kept open after that, emission halt state is achieved. In case an abnormality is discovered during selfdiagnosis, the device is put in the lockout state at that instant, and the control output OSSD) and alarm outputs are fixed at the OFF state. Emission halt state is achieved when no abnormality is detected during self-diagnosis and the test input is continued to be kept open after that. During emission halt, control output OSSD) and alarm output switch to the OFF state. By using this function, malfunction due to extraneous noise, or abnormality in control output OSSD) and alarm output, can be determined even from the equipment side.
