Short-circuit protection Incorporated
Self-diagnosis output
<NPN output type>
NPN open-collector transistor
• Maximum sink current: 50 mA
• Applied voltage: 30 V DC or less (between self-diagnosis output and 0 V)
• Residual voltage: 1.0 V or less (at 50 mA sink current)
0.4 V or less (at 16 mA sink current)
<PNP output type>
PNP open-collector transistor
• Maximum source current: 50 mA
• Applied voltage: 30 V DC or less (between self-diagnosis output and +V)
• Residual voltage: 2.0 V or less (at 50 mA source current)
1.0 V or less (at 16 mA source current)
Output operation
ON under unstable sensing condition (restored automatically after 40 ms approx.), or if the sensing output is short-circuited
(restored when short-circuit is rectied).
(For the remote sensitivity adjustment type, it turns ON for 40 ms approx. Also after the remote sensitivity input is received.)
Short-circuit protection
–
Response time 0.6 ms or less (0.8 ms or less when the interference prevention function is used)
Operation indicator Red LED (lights up when the sensing output is ON)
Stability indicator Green LED
“RUN” mode: Lights up under stable light received condition or stable dark condition
“SET” mode: At the time of sensitivity setting, blinks twice when the difference between ON and OFF levels is
greater than the hysteresis, but blinks 15 times when it is equal to or less than the hysteresis. Also
blinks twice after the interference prevention is set
“SET” mode → When “SIF” or “RUN” mode is selected: Blinks from 0 to 5 times according to the sensitivity margin
