*1 20% or more reflectance is necessary for the minimum detectable object in the warning zone.
*2 If there is a high reflective background within 1.5 m 4.921' from the boundary of the protection zone, 200 mm 7.87" must be added as supplementary necessary distance to the protection zone in case of calculation of the minimum safety distance.
*3 The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice.
*4 For the load current calculation of the OSSD output and the AUX output, make sure it is 1.5 A or less when using converter power supply (or 1.0 A or less when the cable length is 25 m 82.02' or more),
and 1.0 A or less when using a battery (or 0.5 A or less when the cable length is 5 m 16.40' or more)
*5 This also takes into account the situations when power is either off or disconnected.
*6 The wiring resistance between the OSSD output and the connected equipment (excluding the resistance of the cable) must be 2.5 Ω or less to ensure operation. However, it must be 1.0 Ω or less if the load current is 300 mA or more.
*7 It must be 10 m 32.81' or less if the power is supplied by battery.
*8 When the setting cover is open, or the connector cable is not connected, the IP65 certification cannot be met. In addition, the SZ-16D doesn't fulfill the requirements of IP65 degree of protection with the connector cable for the RS-422A communication unattached..
*9 The SZ should not be installed so as to have light interference within ±5° to the detection plane.
