%. Ripple P-P 10% or less
Control output
(OSSD 1, OSSD 2)
PNP open-collector transistor/NPN open-collector transistor (switching type)
• For PNP output: Max. source current 200mA
• For NPN output: Max. sink current 200mA
Applied voltage: same as supply voltage (for PNP output: between the control output
(OSSD 1/2) and +V, for NPN output between the control output (OSSD 1/2) and 0V).
• Residual voltage: 2.5V or less (For PNP output: source current 200mA, for NPN
output: sink current 200mA) (when using 10m length cable)
• Leakage current: 200µA or less, when power supply is OFF
• Maximum load capacity: 1µF (no load to maximum output current)
• Load wiring resistance: 3Ω or less
• Operation mode: ON when all beams are received, OFF when one or more beams
are interrupted (Note 1, 2), OFF when fault occurs in the sensor or the
synchronization signal error, too.
• Protection circuit: Incorporated
Response time In normal operation: OFF: 7ms or less, ON: 90ms or less
Auxiliary output
(Non-safety output)
PNP open-collector transistor/NPN open-collector transistor (switching type)
• For PNP output: Max. source current 100mA
• For NPN output: Max. sink current 100mA
• Applied voltage: same as supply voltage (for PNP output: between the auxiliary
output and +V, for NPN output between the auxiliary output and 0V)
• Residual voltage: 2.5V or less (In case of selecting PNP output: source current
100mA, in case of selecting NPN output: sink current 100mA) (when using 10m
length cable)
• Operation mode: When OSSDs are ON: OFF, When OSSDs are OFF: ON (factory
setting). This setting can be changed with the optional handy controller SFC-HC.
• Protection circuit: Incorporated
