Power voltage24 V DC+20-30 % Ripple P-P 10 % or less (excluding voltage drop due to cable)
(Note): In consideration of the voltage drop caused by the cable, use Control output (OSSD 1, OSSD 2) source / sink current and cable length as a guideline.
Control outputs (OSSD 1, OSSD 2)PNP open-collector transistor / NPN open collector transistor (selectable)

<PNP output selected>
・Maximum source current : 350 mA
・Applied voltage : Same as supply voltage
(between control output and +V)
・Residual voltage : 2 V or less (source current 350 mA)
(excluding voltage drop due to cable)
・Leakage current : 0.2 mA or less (including power OFF state)
・Maximum load capacity : 2.2 μF
・Load wiring resistance : 3 Ω or less

<NPN output selected>
・Maximum sink current : 350 mA
・Applied voltage : Same as supply voltage
(between control output and 0 V)
・Residual voltage : 2 V or less (sink current 350 mA)
(excluding voltage drop due to cable)
・Leakage current : 0.2 mA or less (including power OFF state)
・Maximum load capacity : 2.2 μF
・Load wiring resistance : 3 Ω or less
Control outputs (OSSD 1, OSSD 2):Operation modeON when all beams are received, OFF when one or more beams are blocked
(Also OFF when internal sensor error or synchronization signal error occurs)
(Note): Note that the setting cannot be changed when SF4D-□-01 is used.
Control outputs(OSSD1, OSSD2):Protection circuitIncorporated
Control output(OSSD 1, OSSD 2):Response timeOFF response : 10 ms or less (Not connected in series / parallel), 18 ms or less (Connected in series / parallel)(Note 1)
ON response : 50 ms or less (Note 2)(Note 3)
(Note 1): For response times by number of beams, refer to the Control output (OSSD 1, OSSD 2) OFF response times.
(Note 2): Because the control output (OSSD 1, OSSD 2) must be OFF for at least 80 ms, the ON response will be delayed more than 50 ms when the light blocked time is less than 30 ms.
(Note 3): When optical synchronization is selected, if the beam axes of both the top end and bottom end are blocked, the ON response speed decreases by as much as 1 sec.
