    Min. sensing objectdia. 30 mm dia. 1.181 in opaque object
    (Note) In this light curtain, the floating blanking function can be set by using the Handy-controller (SF-HC)(optional). When the floating blanking function is used, the size of the min. sensing object is changed. For details on the floating blanking function, refer to SF4B Ver.2 series.
    Effective aperture angleplus or minus 2.5degrees or less [for an operating range exceeding 3 m 9.843 ft (conforming to IEC 61496-2 / UL 61496-2)]
    Power voltage24 V DC plus or minus 10 % Ripple P-P 10 % or less
    Control outputs (OSSD 1, OSSD 2)Semiconductor output (PNP output equivalent) 2 outputs
    - Maximum source current: 200 mA
    - Applied voltage: Same as supply voltage (between control output and +V)
    - Residual voltage: 2.5 V or less (at 200 mA source current)
    Control outputs (OSSD 1, OSSD 2):Operation modeON when all beam channels are received, OFF when one or more beam channels are interrupted (OFF also in case of any malfunction in the light curtain or the synchronization signal)
    Response timeIn normal operation: OFF response 11 ms or less, ON response 70 ms or less
    In the blanking function set condition: OFF response 15 ms or less, ON response 70 ms or less
    Response time:Series connectionIn normal operation: OFF response 20 ms or less, ON response 70 ms or less
    In the blanking function set condition: OFF response 20 ms or less, ON response 70 ms or less
    Auxiliary output (Non-safety output)PNP open-collector transistor
    - Maximum source current: 60 mA
    - Applied voltage: Same as supply voltage (between auxiliary output and +V)
    - Residual voltage: 2.5 V or less (at 60 mA source current)
    Auxiliary output (Non-safety output):Operation modeOFF when control outputs are ON, ON when control outputs are OFF (It is possible to use the handy-controller to switch the mode to ON when control outputs are ON and OFF when control outputs are OFF.)
