■For your safety
In using the light curtain, please establish a control system to satisfy the below items in order to ensure safety with a total system.
>>Precautions for use
Application of IEC 61496 (Type 2) international standard
The SF2-N series has the same level of safety built into the sensor body as conventional fail-proof type area sensors, and conforms to European and North American safety standards. It can be used in any workplace throughout the world.
Compact design, 28mm wide and 19mm thick
The design is compact, with a width of only 28mm and a thickness of 19mm, and no exclusive controller is required, so that minimum space is required for installation. The small amount of space needed allows the sensors to be incorporated into machinery.
Distinguishes extraneous light to prevent malfunction
The ELC (Extraneous Light Check) function prevents malfunction due to extraneous light, such as from other nearby passing sensors, AGVs, patrol lights or spatter lights.
What is Extraneous Light Check (ELC) function?
This function distinguishes between light from the sensor itself and light from extraneous sources, and reduces the effect of the extraneous light if it is received by the sensor
Convenient indicators allow easy beam alignment
The beam-axis alignment indicators are distributed along the sensors in four sections. The indicators of the sections whose beams are aligned light up in red, and when all beams are aligned, the indicators light up in green.
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.
Wire-saving by series connection
Using the optional series connection cable, a maximum of 3 sets of sensors with a total of 128 beam channels (for 20mm beam pitch type) or 64 beam channels (for 40mm beam pitch type) can be connected in series. Hence, even L-shaped and U-shaped areas can be easily covered. Previously, separate wiring was required for 3 sets of sensors. But now, wiring equivalent to that for only one set is required, thus saving troublesome wiring and costs.
